1.  Introduction
=20
   Deterministic Networking (DetNet) is a service that can be offered by
   a network to DetNet flows.  DetNet provides these flows extremely low
   packet loss rates and assured maximum end-to-end delivery latency.
   General background and concepts of DetNet can be found in
   [I-D.ietf-detnet-architecture].
=20
   This document specifies the DetNet data plane.  It defines how DetNet
   traffic is encapsulated at the network layer, and how DetNet-aware
   nodes can identity DetNet flows.  Two data plane definitions are
   given.
=20
   o  PW-based: One solution is based on PseudoWires (PW) [RFC3985] and
      makes use of multi-segment pseudowires (MS-PW) [RFC6073] to map
      DetNet Relay and Edge Nodes [I-D.ietf-detnet-architecture]
      [I-D.ietf-detnet-dp-alt] to PW architecture.  The PW-based data
      plane can be run over an MPLS [RFC4448] [RFC6658] Packet Switched
      Network (PSN).
=20
SB> This is really an MPLS one. The world of IP PWs is a bit scruffy =
with
SB> some work in PWE3 and some in L2TPext which really went their own =
ways.
SB> There is for example no MS-PW IP design.
SB>
SB> The MS-PW approach needs to be examined more closely by the WG and =
thus
SB> at this stage be marked as provisional.
=20
  o  Native-IP: The other solution is based on IP header fields, namely
      on the IPv6 Flow Label and a new DetNet Control Word extension
      header option.  It is targeted for native IPv6 networks.
=20
SB> The IP solution has not been properly examined by the WG and needs
SB> to be marked as provisional.
=20
   It is worth noting that while PWs are designed to work over IP PSNs
   this document describes a native-IP solution that operates without
   PWs.  The primary reason for this is the benefit gained by enabling
   the use of a normal application stack, where transport protocols such
   as TCP or UDP are directly encapsulated in IP.
=20
SB> We clearly need to look at the implications of running this with=20
SB> a new IP header extension. Firstly we need input from 6man, but
SB> we also need to understand what happens in middle boxes, other=20
SB> components of the host stack etc.
=20
   This document specifies the encapsulation for DetNet flows, including
   a DetNet Control Word (CW).  Furthermore, it describes how DetNet
   flows are identified, how DetNet Relay and Edge nodes work, and how
   the Packet Replication and Elimination function (PREF) is implemented
=20

   with these two data plane solutions.  This document does not define
   the associated control plane functions, or Operations,
   Administration, and Maintenance (OAM).  It also does not specify
   traffic handling capabilities required to deliver congestion
   protection and latency control to DetNet flows as this is defined to
   be provided by the underlying MPLS or IP network.
=20
SB> OK, although I think that this may be a mistake. There may well be =
some
SB> coupling needed between the Detnet DP and the =
substrate/transport/underlay
SB> needed to make this work. If this is a genuine technical layering we =

SB> should talk about it. If this is an artificial constraint imposed
SB> by the IESG we need to talk to them.
=20
=20
 2.  Terminology
=20
2.1.  Terms used in this document
=20
   This document uses the terminology established in the DetNet
   architecture [I-D.ietf-detnet-architecture] and the DetNet Data Plane
   Solution Alternatives [I-D.ietf-detnet-dp-alt].
=20
   The following terms are also used in this document:
=20
   DA-T-PE       MPLS based DetNet edge node: a DetNet-aware PseudoWire
                 Terminating Provider Edge (T-PE).
=20
   DA-S-PE       MPLS based DetNet relay node: a DetNet-aware PseudoWire
                 Switching Provider Edge (S-PE).
=20
SB> We need to look at whether the S-PE concept is the best fit, or =
whether
SB> we should use introduce a Detnet relay to do this. An S-PE just=20
SB> swaps the PW label, but Detnet needs it to do more and a better =
model
SB> might be a new construct. However we could also discard the relay
SB> concept and run 1+n end to end, in which case the S-PEs would retain
SB> their original function.
=20
=20
   T-Label       A label used to identify the LSP used to transport a
                 DetNet flow across an MPLS PSN, e.g., a hop-by-hop
                 label used between label switching routers (LSR).
=20
   S-Label       A DetNet node to DetNet node "service" label that is
                 used between DA-*-PE devices.
=20
   PW Label      A PseudoWire label that is used to identify DetNet flow
                 related PW Instances within a PE node.
=20
   Flow Label    IPv6 header field that is used to identify a DetNet
                 flow (together with the source IP address field).
=20
SB> If this is the IPv6 Flow label I think caution is needed as I don't =
think
SB> the handling of this is well defined or consistently implemented in
SB> networking equipment.
=20
=20
   local-ID      An edge and relay node internal construct that uniquely
                 identifies a DetNet flow.  It may be used to select
                 proper forwarding and/or DetNet specific service
                 function.
=20
SB> Is this really an internal construct, or is it an on the wire =
construct?
SB> If it is needed end to end, I don't think it is correct to describe =
it
SB> as an internal construct. When you say "select" presumably you mean
SB> by potentially any DN aware node on the path?
=20
=20
   PREF          A Packet Replication and Elimination Function (PREF)
                 does the replication and elimination processing of
                 DetNet flow packets in edge or relay nodes.  The
                 replication function is essentially the existing 1+1
                 protection mechanism.  The elimination function reuses
                 and extends the existing duplicate detection mechanism

   This document describes how to use IP and/or MPLS to support a data
   plane method of flow identification and packet formwarding over
   layer-3.  Two different cases are covered: (i) the inter-connect
   scenario, in which IEEE802.1 TSN is routed over a layer-3 network
   (i.e., to enlarge the layer-2 domain), and (ii) native connectivity
   between DetNet-aware end systems.  Figure 1 illustrates an exemplary
   scenario.

   Figure 2 illustrates how DetNet can provide services for IEEE
   802.1TSN end systems over a DetNet enabled network.  The edge nodes
   insert and remove required DetNet data plane encapsulation.  The 'X'
   in the edge and relay nodes represents a potential DetNet flow packet
   replication and elimination point.  This conceptually parallels L2VPN
   services, and could leverage existing related solutions as discussed

4.1.  DetNet data plane encapsulation requirements
=20
   Two major groups of scenarios can be distinguished which require flow
   identification during transport:
=20
   1.  DetNet function related scenarios:
=20
       *  Congestion protection and latency control: usage of allocated
          resources (queuing, policing, shaping).
=20
       *  Explicit routes: select/apply the flow specific path.
=20
       *  Service protection: recognize DetNet compound and member flows
          for replication an elimination.
=20
SB> I am not sure whether the correct architectural construct is flow
SB> or flow group. Flow suggests that sharing/aggregation is not allowed
SB> but whether this is allowed or not is an application specific issue.
=20
SB> I think that there needs to be some clarification as to whether FG =
is
SB> is understood by the DN system exclusively or whether there is an=20
SB> expectation that it is understood by the underlay.
=20
=20
 2.  OAM function related scenarios:
=20
       *  troubleshooting (e.g., identify misbehaving flows, etc.)
=20
       *  recognize flow(s) for analytics (e.g., increase counters,
          etc.)
=20
       *  correlate events with flows (e.g., volume above threshold,
          etc.)
=20
       *  etc.
=20
   Each node (edge, relay and transit) use a local-ID of the DetNet-
   (compound)-flow in order to accomplish its role during transport.
=20
=20

=20
Internet-Draft       DetNet Data Plane Encapsulation           June 2017
=20
=20
   Recognizing the DetNet flow is more relaxed for edge and relay nodes,
   as they are fully aware of both the DetNet service and transport
   layers.  The primary DetNet role of intermediate transport nodes is
   limited to ensuring congestion protection and latency control for the
   above listed DetNet functions.
=20
   The DetNet data plane allows for the aggregation of DetNet flows,
   e.g., via MPLS hierarchical LSPs, to improved scaling.  When DetNet
   flows are aggregated, transit nodes may have limited ability to
   provide service on per-flow DetNet identifiers.  Therefore,
   identifying each individual DetNet flow on a transit node may not be
   achieved in some network scenarios, but DetNet service can still be
   assured in these scenarios through resource allocation and control.
=20
SB> You could introduce the concept of a flow group identified into the
SB> packet. You may also include a flow id at a lower layer.
=20
=20
   On each node dealing with DetNet flows, a local-ID is assumed to
   determine what local operation a packet goes through.  Therefore,
   local-IDs MUST be unique on each edge and relay nodes.  Local-ID MUST
   be unambiguously bound to the DetNet flow.
=20
SB> I am confused as to what you mean by local ID. Is this an internal
SB> construct which packet parameters map to, in which case why is it
SB> being called up? IETF practise is to specify on the wire behaviour
SB> but not internal behaviour of equipments.
=20
=20
 5.  DetNet data plane solution
=20
5.1.  DetNet specific packet fields
=20
   The DetNet data plane encapsulation should include two DetNet
   specific information element in each packet of a DetNet flow: (1)
   flow identification and (2) sequence number.
=20
SB> should, SHOULD, must or MUST?
=20
=20
   The DetNet data plane encapsulation may consists further elements
   used for overlay tunneling, to distinguish between DetNet member
   flows of the same DetNet compound flow or to support OAM functions.
=20
5.2.  DetNet encapsulation
=20
   This document specifies two encapsulations for the DetNet data plane:
   (1) PseudoWire (PW) for MPLS PSN and (2) native IPv6 based
   encapsulation for IP PSN.
=20
5.2.1.  PseudoWire-based data plane encapsulation
=20
   Figure 5 illustrates a DetNet PW encapsulation over an MPLS PSN.  The
   PW-based encapsulation of the DetNet flows fits perfectly for the
   Layer-2 interconnect deployment cases (see Figure 2).  Furthermore,
   end to end DetNet service i.e., native DetNet deployment (see
   Figure 3) is also possible if DetNet-aware end systems are capable of
   initiating and termination MPLS encapsulated PWs.  It is also
   possible use the same encapsulation format with a Packet PW over MPLS
   [RFC6658].  Transport of IP encapsulated DetNet flows, see
   Section 5.2.2, over DetNet PWs is also possible.  Interworking

=20
=20
   between PW- and IPv6-based encapsulations is discussed further in
   Section 7.6.
=20
   The PW-based DetNet data plane encapsulation consists of:
=20
   o  DetNet control word (d-CW) containing sequencing information for
      packet replication and duplicate elimination purposes.  There is a
      separate sequence number space for each DetNet flow.
=20
   o  PseudoWire Label (PW Label) that is a standard PW label
      identifying a DetNet flow and a PW Instance within a (DA-)T-PE or
      (DA-)S-PE device.
=20
   o  An optional S-Label that represents DetNet Service LSP used
      between (DA-)T-PE or (DA-)S-PE nodes.  One possible use of an
      S-Label is to identify the different DetNet member flows used to
      provide protection to a DetNet composite flow, perhaps even when
      both LSPs appear on the same link for some reason.
=20
SB> This needs some discussion by the WG.
=20
   o  MPLS transport LSP label(s) (T-label) which may be a hop-by-hop
      label used between LSRs.
=20
SB> Ordinarily this will of course be PHPed before arrival at an x-PE.

=20
SB> This part of the design needs to be marked as provisional until it =
has

=20
   Figure 7 illustrates a DetNet native IPv6 encapsulation.  The native
   IPv6 encapsulation is meant for end to end Detnet service use cases,
   where the end stations are DetNet-aware (see Figure 4).  Technically
   it is possible to use the IPv6 encapsulation to tunnel any traffic
   over a DetNet enabled network, which would make native IPv6
   encapsulation also a valid data plane choice for an interconnect use
   case (see Figure 2).
=20
   The native IPv6-based DetNet data plane encapsulation consists of:
=20
   o  IPv6 header as the transport protocol.
=20
   o  IPv6 header Flow Label that is used to help to identify a DetNet
      flow (i.e., roughly an equivalent to the PW Label).  A Flow Label
      together with the IPv6 source address uniquely identifies a DetNet
      flow.
=20
SB> Have we validated that it is unconditionally safe to make this=20
SB> assumption about the use of the FL?
=20
=20
 o  DetNet Control Word IPv6 Destination Option containing sequencing
      information for packet replication and duplicate elimination
      function (PREF) purposes.  The DetNet Destination Option is
      equivalent to the DetNet Control Word.
=20
   A DetNet-aware end station (a host) or an intermediate node
   initiating an IPv6 packet is responsible for setting the Flow Label,
   adding the required DetNet Destination Option, and possibly adding a
   routing header such as the segment routing option (for pre-defined
   paths [I-D.ietf-6man-segment-routing-header]). =20
=20
SB> We will probably need to agree an option ordering, and need to
SB> note that the 6man IPv6 solution already operates on the edge of the =

SB> ability of h/w to see that far into the packet.
=20
   The payload of the
   native IPv6 encapsulation is any payload protocol that can be
   identified using the Next Header field either in the IPv6 packet
   header or in the last IPv6 extension header.
=20
SB> I am not sure the above is needed since it is by definition correct.

5.3.1.  PseudoWire encapsulation
=20
   RFC3985 Section 5.2.1. describes PW sequencing provides a duplicate
   detection service among other things.  This specification clarifies
   this definition as follows:
=20
      DetNet flows that need to undergo PREF processing MUST have the
      same PW Label when they arrive at the DA-*-PE node.
=20
   From the label stack processing point of view receiving the same
   label from multiple sources is analogous to Fast Reroute backup
   tunnel behavior [RFC4090].  The PW Label for a DetNet flow can be
   different on each PW segment.
=20
SB> I am not sure of the utility of this reference. In FRR you should =
not
SB> receive packets concurrently on two paths. It seems fine to state =
the
SB> the requirement that a single label is used for both paths.
=20
=20
 5.3.2.  Native IPv6 encapsulation
=20
   The DetNet flow identification is based on the IPv6 Flow Label and
   the source address combination.  The two fields uniquelly identify
   the end to end native IPv6 encapsulated DetNet flow.  Obviously, the
   identification fails if any intermediate node modifies either the
   source address or the Flow Label.
=20
SB> See earlier. If there are enough IPv6 addresses to address video
SB> fragments, why not DN flows? Then this problem goes away.
=20
=20
 6.  PREF specific considerations
=20
   This section applies equally to DetNet flows transported via IPv6 and
   MPLS.  While flow identification and some header related processing
   will differ between the two, the considerations covered in this
   section are common to both.
=20
6.1.  PseudoWire-based data plane
=20
6.1.1.  Forwarder clarifications
=20
   The DetNet specific new functionality in an edge or relay node
   processing is the packet replication and duplication elimination
   function (PREF).  This function is a part of the DetNet-aware
   "extended" forwarder.  The PREF processing is triggered by the
   received packet of a DetNet flow.=20
=20
SB> I am not sure what you mean by triggered here. Hopefully we
SB> are not thinking of dataplane triggered configuration?
=20
    Basically the forwarding entry has
   to be extended with a "PREF enabled" boolean configuration switch
   that is associated with the normal forwarding actions (e.g., in case
   of MPLS a swap, push, pop, ..).  The output of the PREF elimination
   function is always a single packet.  The output of the PREF
   replication function is always one or more packets (i.e., 1:M
   replication).  The replicated packets MUST share the same DetNet
   control word sequence number.
=20
   The complex part of the DetNet PREF processing is tracking the
   history of received packets for multiple DetNet member flows.  These
=20

=20
Internet-Draft       DetNet Data Plane Encapsulation           June 2017
=20
=20
   ingress DetNet member flows (to a node) MUST have the same local-ID
   if they belong to the same DetNet-(compound)-flow and share the same
   sequence number counter and the history information.
=20
   The edge and relay node internal procedures of the PREF are
   implementation specific.  The order of a packet elimination or
   replication is out of scope in this specification.  However, care
   should be taken that the replication function does not actually
   loopback packets as "replicas".  Looped back packets include
   artificial delay when the node that originally initiated the packet
   receives it again.  Also, looped back packets may make the network
   condition to look healthier than it actually is (in some cases link
   failures are not reflected properly because looped back packets make
   the situation appear better than it actually is).
=20
SB> There needs to be some text about preventing a node ever receiving =
its
SB> own replicated packets. Indeed that would suggest that the flow
SB> id should be changed and replication should only take place on=20
SB> configured flow IDs.
=20
SB> I have a feeling that this would all be a lot safer if replication
SB> only happened at ingress and we managed the diversity of the paths.
=20
=20
 6.1.2.  Edge node processing clarifications
=20
   The DetNet data plane solution overloads the edge node with DetNet
   Edge Node functions.  Edge nodes are also aware of DetNet flows and
   may need to operate upon those.  Figure 9 illustrates the overall
   edge device functions.  The figure shows both physical attachment
   circuit (AC) (e.g., Ethernet [RFC4448]) connecting to the edge node,
   and a packet service connecting to the edge node via an embedded
   router function (similarly as described e.g., in [RFC6658]).  Whether
   traffic flow from a client AC and PSN tunnel receives DetNet specific
   treatment is up to a local configuration and policy.

                   Figure 9: DetNet Edge Node processing
=20
   An edge node participates to the packet replication and duplication
   elimination.  Required processing is done within an extended
   forwarder function.  In the case the native service processing (NSP)
   is IEEE 802.1CB [IEEE8021CB] capable, the packet replication and
   duplicate elimination MAY entirely be done in the NSP and bypassing
   the DetNet flow encapsulation and logic entirely, and thus is able to
   operate over unmodified implementation and deployment.  The NSP
   approach works only between edge nodes and cannot make use of relay
   nodes (see Section 6.1.3).
=20
SB> This would be a fine way to operate the PW system - edge to edge.
=20
=20
   The DetNet-aware extended forwarder selects the egress DetNet member
   flow based on the DetNet forwarding rules.  In both "normal AC" and
   "Packet AC" cases there may be no DetNet encapsulation header
   available yet as it is the case with relay nodes (see Section 6.1.3).
   It is the responsibility of the extended forwarder within the edge
   node to push the DetNet specific encapsulation (if not already
   present) to the packet before forwarding it to the appropriate egress
   DetNet member flow instance(s). =20
=20
SB> I am not convinced of the wisdom of having a mid-point node convert
SB> a flow into a DN flow, which is what you are implying here. This =
seems
SB> like an ingress function.
=20
   The extended forwarder MAY copy the
   sequencing information from the native DetNet packet into the DetNet
   sequence number field and vice versa.  If there is no existing
   sequencing information available in the native packet or the

=20
   forwarder chose not to copy it from the native packet, then the
   extended forwarder MUST maintain a sequence number counter for each
   DetNet flow (indexed by the DetNet flow identification).
=20
6.1.3.  Relay node processing clarifications
=20
   The DetNet data plane solution overloads a relay node with DetNet
   Relay node functions. =20
=20
SB> I don't think that a relay node in not a normal construct so=20
SB> I am not sure "overload" is the right term here.
=20
   Relay node is aware of DetNet flows and may
   operate upon those.  Figure 10 illustrates the overall DetNet relay
   device functions.
=20
   A DetNet Relay node participates to the packet replication and
   duplication elimination.  This processing is done within an extended
   forwarder function.  Whether an ingress DetNet member flow receives
   DetNet specific processing depends on how the forwarding is
   programmed.  For some DetNet member flows the relay node can act as a
   normal relay node and for some apply the DetNet specific processing
   (i.e., PREF). =20
=20
SB> Again relay node is not a normal term, so am not sure what it does
SB> in the absence of a PREF function.
=20
   It is also possible to treat the relay node as a
   transit node, see Section 7.3.  Again, this is entirely up to how the
   forwarding has been programmed.
=20
   The DetNet-aware forwarder selects the egress DetNet member flow
   segment based on the flow identification.  The mapping of ingress
   DetNet member flow segment to egress DetNet member flow segment may
   be statically or dynamically configured.  Additionally the DetNet-
   aware forwarder does duplicate frame elimination based on the flow
   identification and the sequence number combination.  The packet
   replication is also done within the DetNet-aware forwarder.  During
   elimination and the replication process the sequence number of the
   DetNet member flow MUST be preserved and copied to the egress DetNet
   member flow.

7.  Other DetNet data plane considerations
=20
7.1.  Class of Service
=20
   Class and quality of service, i.e., CoS and QoS, are terms that are
   often used interchangeably and confused.  In the context of DetNet,
   CoS is used to refer to mechanisms that provide traffic forwarding
   treatment based on aggregate group basis and QoS is used to refer to
   mechanisms that provide traffic forwarding treatment based on a
   specific DetNet flow basis.  Examples of existing network level CoS
   mechanisms include DiffServ which is enabled by IP header
   differentiated services code point (DSCP) field [RFC2474] and MPLS
   label traffic class field [RFC5462], and at Layer-2, by IEEE 802.1p
   priority code point (PCP).
=20
   CoS for DetNet flows carried in PWs and MPLS is provided using the
   existing MPLS Differentiated Services (DiffServ) architecture

=20
=20
   [RFC3270].  Both E-LSP and L-LSP MPLS DiffServ modes MAY be used to
   support DetNet flows.  The Traffic Class field (formerly the EXP
   field) of an MPLS label follows the definition of [RFC5462] and
   [RFC3270].  The Uniform, Pipe, and Short Pipe DiffServ tunneling and
   TTL processing models are described in [RFC3270] and [RFC3443] and
   MAY be used for MPLS LSPs supporting DetNet flows.  MPLS ECN MAY also
   be used as defined in ECN [RFC5129] and updated by [RFC5462].
=20
   CoS for DetNet flows carried in IPv6 is provided using the standard
   differentiated services code point (DSCP) field [RFC2474] and related
   mechanisms.  The 2-bit explicit congestion notification (ECN)
   [RFC3168] field MAY also be used.
=20
   One additional consideration for DetNet nodes which support CoS
   services is that they MUST ensure that the CoS service classes do not
   impact the congestion protection and latency control mechanisms used
   to provide DetNet QoS.  This requirement is similar to requirement
   for MPLS LSRs to that CoS LSPs do not impact the resources allocated
   to TE LSPs via [RFC3473].
=20
7.2.  Quality of Service
=20
   Quality of Service (QoS) mechanisms for flow specific traffic
   treatment typically includes a guarantee/agreement for the service,
   and allocation of resources to support the service.  Example QoS
   mechanisms include discrete resource allocation, admission control,
   flow identification and isolation, and sometimes path control,
   traffic protection, shaping, policing and remarking.  Example
   protocols that support QoS control include Resource ReSerVation
   Protocol (RSVP) [RFC2205] (RSVP) and RSVP-TE [RFC3209] and [RFC3473].
   The existing MPLS mechanisms defined to support CoS [RFC3270] can
   also be used to reserve resources for specific traffic classes.
=20
   In addition to path pinning and packet replication and elimination,
   described in Section 5 above, DetNet provides zero congestion loss
   and bounded latency and jitter.=20
=20
SB> I just searched from the beginning of the document and this was the=20
SB> the first reference I found to pinning.
=20
    As described in
   [I-D.ietf-detnet-architecture], there are different mechanisms that
   maybe used separately or in combination to deliver a zero congestion
   loss service.  These mechanisms are provided by the either the MPLS
   or IP layers, and may be combined with the mechanisms defined by the
   underlying network layer such as 802.1TSN.
=20
   A baseline set of QoS capabilities for DetNet flows carried in PWs
   and MPLS can provided by MPLS with Traffic Engineering (MPLS-TE)
   [RFC3209] and [RFC3473].  TE LSPs can also support explicit routes
   (path pinning).  Current service definitions for packet TE LSPs can
   be found in "Specification of the Controlled Load Quality of
   Service", [RFC2211], "Specification of Guaranteed Quality of

   Service", [RFC2212], and "Ethernet Traffic Parameters", [RFC6003].
   Additional service definitions are expected in future documents to
   support the full range of DetNet services.  In all cases, the
   existing label-based marking mechanisms defined for TE-LSPs and even
   E-LSPs are use to support the identification of flows requiring
   DetNet QoS.
=20
   QoS for DetNet flows carried in IPv6 MUST be provided locally by the
   DetNet-aware hosts and routers supporting DetNet flows.  Such support
   will leverage the underlying network layer such as 802.1TSN.  The
   traffic control mechanisms used to deliver QoS for IP encapsulated
   DetNet flows are expected to be defined in a future document.  From
   an encapsulation perspective, and as defined in Section 5.2.2, the
   combination of the Flow Label together with the IP source address
   uniquely identifies a DetNet flow.
=20
   Packets that are marked with a DetNet Class of Service value, but
   that have not been the subject of a completed reservation, can
   disrupt the QoS offered to properly reserved DetNet flows by using
   resources allocated to the reserved flows.  Therefore, the network
   nodes of a DetNet network SHOULD:
SB> Why not MUST?
=20
 o  Defend the DetNet QoS by discarding or remarking (to a non-DetNet
      CoS) packets received that are not the subject of a completed
      reservation.
=20
   o  Not use a DetNet reserved resource, e.g. a queue or shaper
      reserved for DetNet flows, for any packet that does not carry a
      DetNet Class of Service marker.
=20
7.3.  Cross-DetNet flow resource aggregation
=20
   The ability to aggregate individual flows, and their associated
   resource control, into a larger aggregate is an important technique
   for improving scaling of control in the data, management and control
   planes.  This document identifies the traffic identification related
   aspects of aggregation of DetNet flows.  The resource control and
   management aspects of aggregation (including the queuing/shaping/
   policing implications) will be covered in other documents.  The data
   plane implications of aggregation are independent for PW/MPLS and IP
   encapsulated DetNet flows.
=20
   DetNet flows transported via MPLS can leverage MPLS-TE's existing
   support for hierarchical LSPs (H-LSPs), see [RFC4206].  H-LSPs are
   typically used to aggregate control and resources, they may also be
   used to provide OAM or protection for the aggregated LSPs.  Arbitrary
   levels of aggregation naturally falls out of the definition for
   hierarchy and the MPLS label stack [RFC3032].  DetNet nodes which

=20
=20
   support aggregation (LSP hierarchy) map one or more LSPs (labels)
   into and from an H-LSP.  Both carried LSPs and H-LSPs may or may not
   use the TC field, i.e., L-LSPs or E-LSPs.  Such nodes will need to
   ensure that traffic from aggregated LSPs are placed (shaped/policed/
   enqueued) onto the H-LSPs in a fashion that ensures the required
   DetNet service is preserved.
=20
   DetNet flows transported via IP have more limited aggregation
   options, due to the available traffic flow identification fields of
   the IP solution.  One available approach is to manage the resources
   associated with a DSCP identified traffic class and to map (remark)
   individually controlled DetNet flows onto that traffic class.  This
   approach also requires that nodes support aggregation ensure that
   traffic from aggregated LSPs are placed (shaped/policed/enqueued) in
   a fashion that ensures the required DetNet service is preserved.
=20
SB> I am sure we can do better than this with SR, or the use of
SB> routing techniques that map certain addresses to certain paths.
=20
   In both the MPLS and IP cases, additional details of the traffic
   control capabilities needed at a DetNet-aware node may be covered in
   the new service descriptions mentioned above or in separate future
   documents.  Management and control plane mechanisms will also need to
   ensure that the service required on the aggregate flow (H-LSP or
   DSCP) are provided, which may include the discarding or remarking
   mentioned in the previous sections.
=20
7.4.  Bidirectional traffic
=20
   Some DetNet applications generate bidirectional traffic.  Using MPLS
   definitions [RFC5654] there are associated bidirectional flows, and
   co-routed bidirectional flows.  MPLS defines a point-to-point
   associated bidirectional LSP as consisting of two unidirectional
   point-to-point LSPs, one from A to B and the other from B to A, which
   are regarded as providing a single logical bidirectional transport
   path.  This would be analogous of standard IP routing, or PWs running
   over two reciprocal unidirection LSPs.  MPLS defines a point-to-point
   co-routed bidirectional LSP as an associated bidirectional LSP which
   satisfies the additional constraint that its two unidirectional
   component LSPs follow the same path (in terms of both nodes and
   links) in both directions.  An important property of co-routed
   bidirectional LSPs is that their unidirectional component LSPs share
   fate.  In both types of bidirectional LSPs, resource allocations may
   differ in each direction.  The concepts of associated bidirectional
   flows and co-routed bidirectional flows can be applied to DetNet
   flows as well whether IPv6 or MPLS is used.
=20
   While the IPv6 and MPLS data planes must support bidirectional DetNet
   flows, there are no special bidirectional features with respect to
   the data plane other than need for the two directions take the same
   paths.  Fate sharing and associated vs co-routed bidirectional flows

=20
=20
   can be managed at the control level.  Note, that there is no stated
   requirement for bidirectional DetNet flows to be supported using the
   same IPv6 Flow Labels or MPLS Labels in each direction.  Control
   mechanisms will need to support such bidirectional flows for both
   IPv6 and MPLS, but such mechanisms are out of scope of this document.
   An example control plane solution for MPLS can be found in [RFC7551].
=20
7.5.  Layer 2 addressing and QoS Considerations
=20
   The Time-Sensitive Networking (TSN) Task Group of the IEEE 802.1
   Working Group have defined (and are defining) a number of amendments
   to IEEE 802.1Q [IEEE8021Q] that provide zero congestion loss and
   bounded latency in bridged networks.  IEEE 802.1CB [IEEE8021CB]
   defines packet replication and elimination functions that should
   prove both compatible with and useful to, DetNet networks.
=20
   As is the case for DetNet, a Layer 2 network node such as a bridge
   may need to identify the specific DetNet flow to which a packet
   belongs in order to provide the TSN/DetNet QoS for that packet.  It
   also will likely need a CoS marking, such as the priority field of an
   IEEE Std 802.1Q VLAN tag, to give the packet proper service.
=20
   Although the flow identification methods described in IEEE 802.1CB
   [IEEE8021CB] are flexible, and in fact, include IP 5-tuple
   identification methods, the baseline TSN standards assume that every
   Ethernet frame belonging to a TSN stream (i.e.  DetNet flow) carries
   a multicast destination MAC address that is unique to that flow
   within the bridged network over which it is carried.  Furthermore,
   IEEE 802.1CB [IEEE8021CB] describes three methods by which a packet
   sequence number can be encoded in an Ethernet frame.
=20
   Ensuring that the proper Ethernet VLAN tag priority and destination
   MAC address are used on a DetNet/TSN packet may require further
   clarification of the customary L2/L3 transformations carried out by
   routers and edge label switches.  Edge nodes may also have to move
   sequence number fields among Layer 2, PW, and IPv6 encapsulations.

=20
=20
   and rough synchronization performance numbers.  Finally, scope time-
   synchronization solution outside data plane.]
=20
   When DetNet is used, there is an underlying assumption that the
   applicaton(s) require clock synchronization such as the Precision
   Time Protocol (PTP) [IEEE1588].  The relay nodes may or may not
   utilize clock synchronization in order to provide zero congestion
   loss and controlled latency delivery.  In either case, there are a
   few possible approaches of how synchronization protocol packets are
   forwarded and handled by the network:
=20
   o  PTP packets can be sent either as DetNet flows or as high-priority
      best effort packets.  Using DetNet for PTP packets requires
      careful consideration to prevent unwanted interactions between
      clock-synchronized network nodes and the packets that synchronize
      the clocks.
=20
   o  PTP packets are sent as a normal DetNet flow through network nodes
      that are not time-synchronized: in this approach PTP traffic is
      forwarded as a DetNet flow, and as such it is forwarded in a way
      that allows a low delay variation.  However, since intermediate
      nodes do not take part in the synchronization protocol, this
      approach provides a relatively low degree of accuracy.
=20
   o  PTP with on-path support: in this approach PTP packets are sent as
      ordinary or as DetNet flows, and intermediate nodes take part in
      the protocol as Transparent Clocks or Boundary Clocks [IEEE1588].
      The on-path PTP support by intermediate nodes provides a higher
      degree of accuracy than the previous approach.  The actual
      accuracy depends on whether all intermediate nodes are PTP-
      capable, or only a subset of them.
=20
   o  Time-as-a-service: in this approach accurate time is provided as-
      a-service to the DetNet source and destination, as well as the
      intermediate nodes.  Since traffic between the source and
      destination is sent over a provider network, if the provider
      supports time-as-a-service, then accurate time can be provided to
      both the source and the destination of DetNet traffic.  This
      approach can potentially provide the highest degree of accuracy.
=20
   It is expected that the latter approach will be the most common one,
   as it provides the highest degree of accuracy, and creates a layer
   separation between the DetNet data and the synchronization service.
=20
   It should be noted that in all four approaches it is not recommended
   to use replication and elimination for synchronization packets; the
   replication/elimination approach may in some cases reduce the

 9.  Management and control considerations
=20
   While management plane and control planes are traditionally
   considered separately, from the Data Plane perspective there is no
   practical difference based on the origin of flow provisioning
   information.  This document therefore does not distinguish between
   information provided by a control plane protocol, e.g., RSVP-TE
   [RFC3209] and [RFC3473], or by a network management mechanisms, e.g.,
   RestConf [RFC8040] and YANG [RFC7950].
=20
   [Editor's note: This section is a work in progress.  discuss here
   what kind of enhancements are needed for DetNet and specifically for
   PREF and DetNet zero congest loss and latency control.  Need to cover
   both traffic control (queuing) and connection control (control
   plane).]
=20
9.1.  PW Label and IPv6 Flow Label assignment and distribution
=20
   The PW label distribution follows the same mechanisms specified for
   MS-PW [RFC6073].  The details of the control plane protocol solution
   required for the label distribution and the management of the label
   number space are out of scope of this document.
=20
   The IPv6 Flow Label distribution and the label number space are out
   of scope of this document.  However, it should be noted that the
   combination of the IPv6 source address and the IPv6 Flow Label is
   assumed to be unique within the DetNet-enabled network.  Therefore,
   as long as each node is able to assign unique Flow Labels for the
   source address(es) it is using the DetNet-enabled network wide flow
   identification uniqueness is guaranteed.

   processing is outside the scope of this document.

Abstract:
   Deterministic Networking (DetNet) provides a capability to carry
   specified unicast or multicast data flows for real-time applications
   with extremely low data loss rates and bounded latency.  Techniques
   used include: 1) reserving data plane resources for individual (or
   aggregated) DetNet flows in some or all of the intermediate nodes
   (e.g. bridges or routers) along the path of the flow; 2) providing
   explicit routes for DetNet flows that do not rapidly change with the
   network topology; and 3) distributing data from DetNet flow packets
   over time and/or space to ensure delivery of each packet's data' in
   spite of the loss of a path.  The capabilities can be managed by
   configuration, or by manual or automatic network management.

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1)      Diego Duovne: Mining Industry use case.
2)      Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proces=
s Bus Communications" and "for IEC 61850 installations only part 9-3 applie=
s:"
3)      Hassan Halabian: 5G Packet Fronthaul
4)      Daniel Huang: Blockchain use case
5)      Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

There was a lot of mention of DetNet in the network slicing BOF.  Should we=
 have that use case?

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn=92t have to be =
in XML.

In several of the cases we have had some email exchanges regarding text wor=
ding =96 it is possible that I already have the latest text, but I would li=
ke for you to send me what you understand to be the latest, to make sure we=
 are in sync.


  1.  Diego Duovne: Mining Industry use case.
  2.  Maik Seewald: =93Comments on section: 3.1.1.2 Intra-Substation Proces=
s Bus Communications=94 and =93for IEC 61850 installations only part 9-3 ap=
plies:=94
  3.  Hassan Halabian: 5G Packet Fronthaul
  4.  Daniel Huang: Blockchain use case
  5.  Xavier Vilajosana: Wind Farm use case


If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn=92t list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

<div>Hi Folks,</div>
<div>The DetNet Use Cases draft 12 will expire in October, i.e. before IETF=
 100, so I plan to have an update before then. According to my notes, there=
 are five items to address, which I enumerate below. If you are one of the =
people mentioned below, please reply
 to indicate your current suggestion for new text for the draft. </div>
<div>&nbsp;</div>
<div>I expect such text to be in a form consistent with the existing use ca=
ses, however it could be plain text or a Word doc, i.e. it doesn=92t have t=
o be in XML.
</div>
<div>&nbsp;</div>
<div>In several of the cases we have had some email exchanges regarding tex=
t wording =96 it is possible that I already have the latest text, but I wou=
ld like for you to send me what you understand to be the latest, to make su=
re we are in sync.
</div>
<div>&nbsp;</div>
<ol style=3D"margin:0; padding-left:36pt">

<div>&nbsp;</div>
<div>If anyone else has any suggestions or comments, or if I somehow lost t=
rack of your request and didn=92t list it below, please reply.</div>
<div>&nbsp;</div>
<div>Please send your replies for each of these potential additions by Sept=
ember 10, 2017 so that I have time to review and integrate.
</div>

Good question. Is anyone interested in contributing text for a network slic=
ing use case?
Ethan.

There was a lot of mention of DetNet in the network slicing BOF.  Should we=
 have that use case?

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1.       Diego Duovne: Mining Industry use case.
2.       Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proce=
ss Bus Communications" and "for IEC 61850 installations only part 9-3 appli=
es:"
3.       Hassan Halabian: 5G Packet Fronthaul
4.       Daniel Huang: Blockchain use case
5.       Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

There was a lot of mention of DetNet in the network slicing BOF.  Should we=

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1.       Diego Duovne: Mining Industry use case.
2.       Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proce=
ss Bus Communications" and "for IEC 61850 installations only part 9-3 appli=
es:"
3.       Hassan Halabian: 5G Packet Fronthaul
4.       Daniel Huang: Blockchain use case
5.       Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

Hi Xuesong,

OK let's give it a try. However since this is new material, it would be goo=
d if we could have some text soon so that we can review it on the list. Whe=
n do you think you can have some text ready for technical review? It doesn'=
t have to be grammatically correct (I can fix that kind of thing later) but=
 it should be technically complete and in the general format of the existin=
g use cases (for example see Daniel's Blockchain text).

Thanks,

Ethan.

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1.       Diego Duovne: Mining Industry use case.
2.       Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proce=
ss Bus Communications" and "for IEC 61850 installations only part 9-3 appli=
es:"
3.       Hassan Halabian: 5G Packet Fronthaul
4.       Daniel Huang: Blockchain use case
5.       Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

Hi Ethan,

We do have some technical materials, but further work should be done to mak=
e it ready for review as a DetNet use case.
I need about 2 weeks to prepare for the text. Is it OK for you?

Hi Xuesong,

OK let's give it a try. However since this is new material, it would be goo=
d if we could have some text soon so that we can review it on the list. Whe=
n do you think you can have some text ready for technical review? It doesn'=
t have to be grammatically correct (I can fix that kind of thing later) but=
 it should be technically complete and in the general format of the existin=
g use cases (for example see Daniel's Blockchain text).

Thanks,

Ethan.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1.       Diego Duovne: Mining Industry use case.
2.       Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proce=
ss Bus Communications" and "for IEC 61850 installations only part 9-3 appli=
es:"
3.       Hassan Halabian: 5G Packet Fronthaul
4.       Daniel Huang: Blockchain use case
5.       Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

Hi Ethan,

We do have some technical materials, but further work should be done to mak=
e it ready for review as a DetNet use case.
I need about 2 weeks to prepare for the text. Is it OK for you?

Hi Xuesong,

OK let's give it a try. However since this is new material, it would be goo=
d if we could have some text soon so that we can review it on the list. Whe=
n do you think you can have some text ready for technical review? It doesn'=
t have to be grammatically correct (I can fix that kind of thing later) but=
 it should be technically complete and in the general format of the existin=
g use cases (for example see Daniel's Blockchain text).

Thanks,

Ethan.

There was a lot of mention of DetNet in the network slicing BOF.  Should we=
 have that use case?

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1.       Diego Duovne: Mining Industry use case.
2.       Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proce=
ss Bus Communications" and "for IEC 61850 installations only part 9-3 appli=
es:"
3.       Hassan Halabian: 5G Packet Fronthaul
4.       Daniel Huang: Blockchain use case
5.       Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

Hi Ethan,

We also provided text (discussed on the mailing list and agreed)
regarding crosshaul for the cellular radio use case. I sent you an e-
mail on April, 3rd. If you want I can resend it to you.

Thanks!

Carlos

Hi Ethan,

Here is a simple introduction about Network Slicing use case for review.
If there is any question or comments, please let me know.

Best Regards,
Xuesong
___________________________________________________________________________=
_______________________

Network Slicing Use Case


1.      Network Slicing Description
Network slicing divides one physical network infrastructure into multiple l=
ogical networks. Each slice, corresponding to a logical network, uses resou=
rces and network functions independently from each other. Network slicing p=
rovides flexibility of resource allocation and service quality customizatio=
n.

Future services will demand the network performance with a wide variety of =
characteristics, such as data rate, latency, loss rate, security and many o=
ther parameters. Ideally, every service can set up its own network satisfyi=
ng its particular performance requirements, which is obviously impossible c=
onsidering the cost. Network slicing can provide a customized slice for a s=
ingle service, and multiple slices can share the same physical network. Thi=
s method can optimize the performance for the service with less cost, and t=
he flexibility of setting up and release the slices also allows the user to=
 allocate the network resources dynamically.

Different from other DetNet use cases, Network slicing is not a specific ap=
plication with QoS requirements. It is proposed as a new requirement for th=
e future network, which is still in discussion, and DetNet is a candidate s=
olution for it.


2.      Network Slicing Use Cases
Network Slicing is a core feature of 5G defined in 3GPP, which is currently=
 under development. A Network Slice in mobile network is a complete logical=
 network including Radio Access Network (RAN) and Core Network (CN). It pro=
vides telecommunication services and network capabilities, which may vary (=
or not) from slice to slice.

5G bearer network is a typical use case of network slicing, including 3 ser=
vice scenarios: enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low La=
tency Communications (URLLC), and massive Machine Type Communications (mMTC=
).


2.1      Enhanced Mobile Broadband (eMBB)
eMBB focuses on services characterized by high data rates, such as high def=
inition (HD) videos, virtual reality (VR), augmented reality (AR), and fixe=
d mobile convergence (FMC).


2.2      Ultra-Reliable and Low Latency Communications (URLLC)
URLLC focuses on latency-sensitive services, such as self-driving, remote s=
urgery, or drone control.


2.3      massive Machine Type Communications (mMTC)
mMTC focuses on services that have high requirements for connection density=
, such as those typical for smart city and smart agriculture use cases.


3.      Using DetNet in Network Slicing
One of the requirements discussed for network slicing is the "hard" separat=
ion of various users' QoS features.  That is, it should be impossible for a=
ctivity, lack of activity, or changes in activity of one or more users to h=
ave any appreciable effect on the QoS parameters of any other users.  Typic=
al techniques used, today, that share a physical network among users, do no=
t offer this kind of insulation.  DetNet can supply point-to-point or point=
-to-multipoint paths that offer bandwidth and latency guarantees to a user =
that cannot be affected by other users' data traffic.

So DetNet is a powerful tool when latency and reliability are required in N=
etwork Slicing, but DetNet can't cover all Network Slicing use cases and th=
ere are some other problems to be solved: Firstly, DetNet is a point-to-poi=
nt or point-to-multipoint technology while Network Slicing needs multi-poin=
t to multi-point guarantee; secondly, the number of flows that can be carri=
ed by DetNet is limited by DetNet scalability. Flow aggregation and queuing=
 management modification may help to fix the problem. More work and discuss=
ions are needed in these topics.


4.      Network Slicing Today and Future
Network slicing can satisfy the requirements of a lot of future deployment =
scenario, but it is still a collection of ideas and analysis, without a spe=
cific technical solution. A lot of technologies, such as Flex-E, Segment Ro=
uting, including DetNet are potential to be used in Network Slicing. (see I=
ETF99 Network Slicing BOF session agenda and materials)


5.      Network Slicing Asks

-          Slice Specification

-          Slice Isolation

-          Service Quality Customization and Guarantee

-          Dynamic control and management

-          OAM

-          Security

Hi Ethan,

We do have some technical materials, but further work should be done to mak=
e it ready for review as a DetNet use case.
I need about 2 weeks to prepare for the text. Is it OK for you?

Hi Xuesong,

OK let's give it a try. However since this is new material, it would be goo=
d if we could have some text soon so that we can review it on the list. Whe=
n do you think you can have some text ready for technical review? It doesn'=
t have to be grammatically correct (I can fix that kind of thing later) but=
 it should be technically complete and in the general format of the existin=
g use cases (for example see Daniel's Blockchain text).

Thanks,

Ethan.

Hi Folks,
The DetNet Use Cases draft 12 will expire in October, i.e. before IETF 100,=
 so I plan to have an update before then. According to my notes, there are =
five items to address, which I enumerate below. If you are one of the peopl=
e mentioned below, please reply to indicate your current suggestion for new=
 text for the draft.

I expect such text to be in a form consistent with the existing use cases, =
however it could be plain text or a Word doc, i.e. it doesn't have to be in=
 XML.

In several of the cases we have had some email exchanges regarding text wor=
ding - it is possible that I already have the latest text, but I would like=
 for you to send me what you understand to be the latest, to make sure we a=
re in sync.

1.       Diego Duovne: Mining Industry use case.
2.       Maik Seewald: "Comments on section: 3.1.1.2 Intra-Substation Proce=
ss Bus Communications" and "for IEC 61850 installations only part 9-3 appli=
es:"
3.       Hassan Halabian: 5G Packet Fronthaul
4.       Daniel Huang: Blockchain use case
5.       Xavier Vilajosana: Wind Farm use case

If anyone else has any suggestions or comments, or if I somehow lost track =
of your request and didn't list it below, please reply.

Please send your replies for each of these potential additions by September=
 10, 2017 so that I have time to review and integrate.

Thanks,
Ethan.

<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=
bri&quot;,&quot;sans-serif&quot;">Network slicing divides one physical netw=
ork infrastructure into multiple logical networks. Each slice, correspondin=
g to a logical network, uses resources and network functions
 independently from each other. Network slicing provides flexibility of res=
ource allocation and service quality customization.
<o:p></o:p></span></p>
<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=

<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=
bri&quot;,&quot;sans-serif&quot;">Future services will demand the network p=
erformance with a wide variety of characteristics, such as data rate, laten=
cy, loss rate, security and many other parameters. Ideally,
 every service can set up its own network satisfying its particular perform=
ance requirements, which is obviously impossible considering the cost. Netw=
ork slicing can provide a customized slice for a single service, and multip=
le slices can share the same physical
 network. This method can optimize the performance for the service with les=
s cost, and the flexibility of setting up and release the slices also allow=
s the user to allocate the network resources dynamically.<o:p></o:p></span>=

<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=

oposed as a new requirement for the future network, which
 is still in discussion, and DetNet is a candidate solution for it. <o:p></=

&quot;">Using DetNet in Network Slicing<o:p></o:p></span></b></p>
<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=
bri&quot;,&quot;sans-serif&quot;">One of the requirements discussed for net=
work slicing is the &quot;hard&quot; separation of various users' QoS featu=
res.&nbsp; That is, it should be impossible for activity, lack of activity,
 or changes in activity of one or more users to have any appreciable effect=
 on the QoS parameters of any other users. &nbsp;Typical techniques used, t=
oday, that share a physical network among users, do not offer this kind of =
insulation.&nbsp; DetNet can supply point-to-point
 or point-to-multipoint paths that offer bandwidth and latency guarantees t=
o a user that cannot be affected by other users' data traffic.<o:p></o:p></=

<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=
bri&quot;,&quot;sans-serif&quot;"><o:p>&nbsp;</o:p></span></p>
<p class=3D"MsoNormal"><span lang=3D"EN-US" style=3D"font-family:&quot;Cali=
bri&quot;,&quot;sans-serif&quot;">So DetNet is a powerful tool when latency=
 and reliability are required in Network Slicing, but DetNet can&#8217;t co=
ver all Network Slicing use cases and there are some other problems
 to be solved: Firstly, DetNet is a point-to-point or point-to-multipoint t=
echnology while Network Slicing needs multi-point to multi-point guarantee;=
 secondly, the number of flows that can be carried by DetNet is limited by =
DetNet scalability. Flow aggregation
 and queuing management modification may help to fix the problem. More work=
 and discussions are needed in these topics.

<div>Hi Folks,</div>
<div>The DetNet Use Cases draft 12 will expire in October, i.e. before IETF=
 100, so I plan to have an update before then. According to my notes, there=
 are five items to address, which I enumerate below. If you are one of the =
people mentioned below, please reply
to indicate your current suggestion for new text for the draft. </div>
<div>=C2=A0</div>
<div>I expect such text to be in a form consistent with the existing use ca=
ses, however it could be plain text or a Word doc, i.e. it doesn=E2=80=99t =
have to be in XML. </div>
<div>=C2=A0</div>
<div>In several of the cases we have had some email exchanges regarding tex=
t wording =E2=80=93 it is possible that I already have the latest text, but=
 I would like for you to send me what you understand to be the latest, to m=
ake sure we are in sync. </div>
<div>=C2=A0</div>
<ol style=3D"margin:0;padding-left:36pt">

<div>If anyone else has any suggestions or comments, or if I somehow lost t=
rack of your request and didn=E2=80=99t list it below, please reply.</div>
<div>=C2=A0</div>
<div>Please send your replies for each of these potential additions by Sept=
ember 10, 2017 so that I have time to review and integrate. </div>
