I don't see where the statements conflict. There are two kinds of 
coexistence: (i) two sets of nodes operating in isolation but in the 
same physical vicinity and (ii) a single set of nodes operating together 
using multiple protocols above the link. A crypto-based solution only 
addresses the former efficiently.

Why? Do we really expect networks to operate with a single protocol? 
LLC/SNAP encapsulation allows multiple protocols to operate along side 
IP. ARP, RARP, MPLS, bridging, just to name a few. Some link-specific 
protocols have nothing to do with IP (e.g. link management), but operate 
in networks that support IP.

I agree with Geoff, IANA should not be concerned with NALP and how it is 
structured. NALP allows protocols that may have nothing to do with IP. 
Typically, the IEEE Registration Authority is responsible for 
maintaining their own namespace with ethertypes. Back in 2005, it seems 
that the WG did consider using LLC/SNAP encapsulation, but that adds 
another 8 octets and was thought to be too heavy weight.

Why? Do we really expect networks to operate with a single protocol? 
LLC/SNAP encapsulation allows multiple protocols to operate along side 
IP. ARP, RARP, MPLS, bridging, just to name a few. Some link-specific 
protocols have nothing to do with IP (e.g. link management), but operate 
in networks that support IP.

I agree with Geoff, IANA should not be concerned with NALP and how it is 
structured. NALP allows protocols that may have nothing to do with IP. 
Typically, the IEEE Registration Authority is responsible for 
maintaining their own namespace with ethertypes. Back in 2005, it seems 
that the WG did consider using LLC/SNAP encapsulation, but that adds 
another 8 octets and was thought to be too heavy weight.

You're right Phil.  IANA is probably responsible for those 6 bits also,
but my thought was, since there are only 64 values, that it is really
probably too small a name space for all of the companies doing
proprietary stuff and if they just set their first two bits to 00 then
at least they can be determined not to be a 6lowpan packet.

Yes it would be a free for all, but after the 64 values are used up,
there is no choice for other companies to but to either not use 00 or to
overlap with an already used value.  I'd prefer to say that those bit
are not defined and application specific rather than try to put some
other structure and naming.

I thought also by allowing them to be application defined, these NALP
protocols would overlap their proprietary protocol and therefore not
need to burn an entire byte for the NALP dispatch and we might get more
companies to accept using just 2 bits to help deal with packet
differentiation.

Hi Geoff:

It is a common thing to reserve one value for experimentations (see RFC
4064 for MIP4).
Maybe we should write a small IETF spec that does this here too.

RFC 4064 intro:
"

   Mobile IPv4 message types range from 0 to 255.  This document
   reserves a message type for experimental purposes, to evaluate
   enhancements to Mobile IPv4 messages before a formal standards
   proposal is issued.

   Without experimental message capability, one would have to select a
   type value from the range defined for IANA assignment, which may
   result in collisions.

   Within a message, Mobile IP defines a general extension mechanism
   allowing optional information to be carried by Mobile IP control
   messages.  Extensions are not skippable if defined in the range [0-
   127] and are skippable if defined in the range [128-255].  This
   document reserves extension types in both the skippable and non-
   skippable ranges for experimental use.

   Mobile IPv4 defines error codes for use by the FA [64-127] and HA
   [128-192].  This document reserves an error code in both of these
   ranges for experimental use.

   The definition of experimental numbers in this document is made
   according to the recommendation of Section 2.2 of BCP 82, RFC 3692.
"

Also, RFCs like 3115 enable vendor extensions, which is also a pretty
good idea that we should keep in mind.

What do you think?

Pascal

Folks,
  Even though we do not have an approved recharter text we have a WG
meeting slot at the next IETF and we need to set the agenda.

>From the last IETF meeting I think that we reached consensus on the work
items for the group:

1. Bootstrapping / Neighbor Discovery
2. Stateful Header Compression
3. Architecture
4. Applications
5. Security Analysis

We decided that we would hold off on Mesh Under (Layer 2 routing) at
this time until the path becomes more clear with respect to the RL2N
proposal.

This group has generated a number of I-Ds, though many are now expired.
Some of the active and expired I-Ds seem closely related to the work
items above.

I have included in this message a list of both the Active and Expired
I-Ds that have been submitted and their abstracts so that you don't have
to search for the I-D information.

Taking into account the above work items, if any of the authors are
interested in presenting their drafts at this next IETF, please let
Carsten or I know soon.

I do hope that we will dust off the ND and security analysis drafts.

If anyone else is planning on submitting a draft, please let us know
soon and also get it submitted - the deadline is the 12th.

	geoff


============== Active Drafts ===============
--- draft-daniel-6lowpan-commissioning-00
The commisioning process defines the startup procedure taken by the
6LoWPAN device. This document defines the startup procedure that all
kinds of devices must take to become part of the network.

--- draft-daniel-6lowpan-hilow-hierarchical-routing-01
The EUI-64 identifier of a 6LoWPAN device can be used as the interface
identifier of the IPv6 address, which can be used for for on-demand
multi-hop routing in 6LoWPAN. One of the distinctive feature of 6LoWPAN
is the capability of the dynamic assignment of 16- bit short addresses.
By utilizing this dynamically assigned short address, a hierarchical
routing which is very scalable can be employed. This This document
defines a dynamic address assignment scheme and hierarchical routing
HiLow) based on the assignment.

--- draft-daniel-6lowpan-load-adhoc-routing-03
6LoWPAN Ad Hoc On-Demand Distance Vector Routing (LOAD) is intended for
use by IEEE 802.15.4 devices in a 6LoWPAN. It is a simplified on-demand
routing protocol based on AODV.

--- draft-daniel-6lowpan-sslp-01
The Simple Service Location Protocol (SSLP) provides a framework for the
discovery and selection of the services working on 6LoWPAN. The protocol
has a simple structure that is easy to be implemented on 6LoWPAN devices
that are characterized by short range, low bit rate and low power. The
protocol also offers a mechanism for interoperability with the IP
networks under SLP. It enables communication between 6LoWPAN and other
IP networks.

--- draft-dokaspar-6lowpan-routreq-02
This document provides the problem statement for mesh routing below the
IP layer (in 6LoWPAN's adaptation layer). It also defines major design
goals and requirements for 6LoWPAN mesh routing considering the
low-power characteristics of the network and its devices.

--- draft-ekim-6lowpan-scenarios-00
This document investigates potential application scenarios and use cases
for low-power wireless personal area networks (LoWPANs).

--- draft-hui-6lowpan-hc1g-00
This document specifies a stateless IP header compression scheme for
IPv6 packet delivery in 6LoWPAN subnetworks. The compression scheme
focuses on LoWPAN nodes that may have global unicast addresses assigned
to their interfaces.

--- draft-hui-6lowpan-interop-00
This memo defines a first step in testing and demonstrating the
interoperability of independent 6LoWPAN implementations.

--- draft-montenegro-6lowpan-dymo-low-routing-03
This document specifies how to use the Dynamic MANET On-demand Routing
Protocol over IEEE802.15.4 networks.

--- draft-oh-6lowpan-packetbb-dymoapp-01
This document describes the applicability of the generalized MANET
packet/message format (packetbb) and the dynamic MANET on-demand (DYMO)
routing protocol over 6LoWPAN. In order to achieve low memory usage and
low processing overhead, this document suggests what is to be modified
from the MANET base specifications.

--- draft-shin-6lowpan-mobility-00
This draft lists mobility scenarios and suggests solutions of how to
provide mobility support in IPv6 low-power personal area networks
(6LoWPANs).

--- draft-thubert-lowpan-backbone-router-00
ISA100.11a is a Working Group at the ISA SP100 standard committee that
covers Wireless Systems for Industrial Automation and Process Control.
The WG is mandated to design a scalable, industrial grade LowPAN for
devices such as sensors, valves, and actuators. The upcoming standard
uses the 6LoWPAN format for the network header. It also introduces the
concept of a Backbone Router to merge small LoWPANs via a high speed
transit and scale the ISA100.11a network. This paper proposes an IPv6
version of the Backbone Router concept.

=============== Expired Drafts ===============
--- draft-chakrabarti-6lowpan-ipv6-nd-03
IETF 6LowPan working group defines IPv6 over low-power personal area
network (IEEE 802.15.4). IEEE 802.15.4 link layer does not have
multicast support, although it supports broadcast. Due to the nature of
LowPan network or sensor networks, broadcast messages should be
minimized. This document suggests some optimizations to IPv6 Neighbor
Discovery related multicast messages in order to reduce signaling in the
low-cost low-powered network.

--- draft-chakrabarti-mobopts-lowpan-req-01
IETF LowPan working group defines IPv6 over low-power personal area
network (IEEE 802.15.4). Lowpan architecture allows routing to take
place at the link layer in order to save payload overhead over the IEEE
802.15.4 link and thus more efficient routing for low power, low
data-rate networks such as sensor networks. This document discusses a
few scenarios of mobility in LowPan network and states mobility
requirements and goals for LowPan networks.

--- draft-daniel-6lowpan-interoperability-01
This document specifies the gateway architecture for the
interoperability between 6LoWPAN and external IPv6 networks. The gateway
does the compression and decompression of IPv6 packets and performs the
mapping between 16 bit short addresses and the IPv6 addresses for both
the external IPv6 networks and 6LowPAN, respectively.

--- draft-daniel-6lowpan-security-analysis-01
This document discusses possible threats and security options for
IPv6-over-IEEE802.15.4 networks. It is an informational document to
raise awareness of security issues in IPv6 lowPan networks.

--- draft-guha-lowpan-mobility-protocol-req-00
In this draft, we propose some protocol requirements for mobility in
LowPAN networks within the context of the IETF LowPAN working group
(IPv6 over IEEE 802.15.4). To achieve mobility in LowPAN networks, there
may be inter-domain movement of network elements across different LowPAN
domains or across domains that do not comprise LowPAN autonomous
systems. To address routing issues in inter-domain LowPAN networks that
conform to fitting within a single IEEE 802.15.4 frame, there are needs
for collaborative and distributed methodologies for route computation,
information storage and retrieval, and security issues in protocols
targeted to LowPAN mobility. This draft proposes some requirements of
mobility in LowPAN protocols from the perspective of
protocol-independent metrics, algorithm complexities, scalability and
security criteria.

--- draft-montenegro-lowpan-aodv-00
This document describes how to use the Ad Hoc On-Demand Vector Protocol
(AODV) in IEEE 802.15.4 networks.

--- draft-sarikaya-6lowpan-forwarding-00
This document describes a simple approach to interconnect IEEE 802.15.4
sensor nodes to IPv6 Internet. The technique requires a gateway node
that is connected to both the sensor network and the IPv6 Internet. The
gateway node runs the serial forwarder over IPv6. Sensor nodes run the
open-source TinyOS operating system and generate TinyOS packets. The
sensor network can be accessed from IPv6 Internet using a Web interface
and the serial forwarder that runs in the applets enables
reception/transmission of TinyOS packets over IPv6.

Dear Geoff,

We submitted application-scenario-01 already.
And, as I remember we agreed to handle 'routing requirements' for
6lowpan mesh routing, although we don't handle the solutions.
Dominik and I will submit routreq-03 for discussion.
We updated the draft based on the meeting discussion.

Thanks,
-eunah (eunsook)

Hi Geoff,

Please see in-line.

> Taking into account the above work items, if any of the authors are
> interested in presenting their drafts at this next IETF, please let
> Carsten or I know soon.

Regarding the 6lowpan-nd draft, we had a presentation at the Chicago IETF
and received comments. We requested for working group approval at that
time, but I was asked to wait for the architecture document.

I had updated the 6lowpan wiki based on architectural assumptions that
6lowpan-nd
draft makes. If anyone has any comments on the topology assumptions,
that would be helpful. For example, should we stick to the
hierarchical topology as
depicted in the IEEE802.15.4 doc? Or should 6lowpan-nd goal  be to also
support a small mesh-network (not only hierarchical mesh as it discusses now)?
I had a request from Jim Bound to think about that option as well.

So far, there is no plan for presentation of this draft in this IETF.
But  comments through Wiki or mailing list would be really helpful.

>
> I do hope that we will dust off the ND and security analysis drafts.


draft-chakrabarti-6lowpan-ipv6-nd version 04 has just been submitted.
The changes are very minimal from 03 currently; it addresses some editorial
comments from Dave Thaler.

We are working on discussing off-line addressing Dave's techical
comments. There will be another revision of the draft before the
Philadelphia IETF.

Besides, if bootstrapping is added as part of that draft, then this
draft will need more update.

Thanks so much,
-Samita

Hi JP:

Thanks a bunch for this charter. I'll try not to rephrase what was =
already discussed with Christian, Anders, Philip and Misha.=20

There's an additional item I'd wish to see either in ROLL or 6LoWPAN and =
I do not know exactly where it belongs, maybe both. The question is =
whether we need to and can document how RFC 4294 applies for sensors, =
and M2M devices in general, whether they act as hosts or as routers.=20

I've seen IPv6 presented as a Pandora box that drags just too much stuff =
to be incorporated in a sensory device. For instance, at the moment, =
SP100.11a endorses 6LoWPAN formats but it's not so clear at all that =
IPv6 itself is mandated. A clear spec with well-documented =
implementation could be a formidable tool to despond to Fear, =
Uncertainty and Defiance.

So maybe we do not need DHCP (a MAY in RFC 4294) and maybe can do =
without multicast at all if ND is supported some other way (such as =
suggested in: =
http://www.ietf.org/internet-drafts/draft-thubert-lowpan-backbone-router-=
00.txt). Maybe NULL encryption and authentication is enough etc, etc...
=20
Being able to define one minimum set and maybe a few other profiles for =
the use cases that we selected could help tremendously.=20

Otherwise I find the charter real well written and easy to digest. From =
the MANEMO experience, I expect that some arguments about the relative =
applicability of existing MANET protocols will be difficult to prove =
without some good simulation work running agreed-upon scenarios.

Finally, I'm a bit confused that it seems that both IPv4 and IPv6 seem =
supported. Ipv4 comes with a lot of overhead like DHCP. I suggest that =
when trouble comes and things can not be done in a common fashion for =
both IP protocols, hen we prioritize IPv6.

Unfortunately, I can not make it to Vancouver, but I do feel that the =
work is really needed so please count my vote in for the adoption of the =
WG.

Cheers,

Pascal

I cannot agree more but this certainly belongs more to 6lowpan if they want
to work on this item. If a RL2N WG gets formed, we should contribute to thi=

This is indeed a key work item. The work has started in the protocol
overview draft (still more work is undoubtedly required).

It is indeed important to have a RL2N solution for both v4 *and* v6, I do
not think that we should try to "prioritize" between the two.

Too bad ... But should a WG be formed, I hope that we'll have you contribut=
e
to this work.

but I do feel that the work is

Will do.

Thanks.

Is there an email thread somewhere that discusses the impact on 6LoWPAN=20
of the security requirements of 4294 and 4303?
My first quick readthrough makes me very uncomfortable that some of the=20
mandates are going to be ugly from a header standpoint.

Subject: [RSN] Here is the new RL2N Proposed Working Charter

Dear all,

As promised, here is the new proposed Working Group, which reflects the
number of comments/suggestions that we received, the pre-WG consensus, ...

Thanks to Dave Ward (RTD AD) for his input.

Proposed RL2N WG Charter

Description of Working Group

L2Ns (Low power and Lossy networks) are typically composed of many embedd=
ed
devices with limited power, memory, and processing resources interconnect=
ed
by a variety of wireless links, such as IEEE 802.15.4, Bluetooth, Low Pow=
er
WiFi.

L2Ns are transitioning to an end-to-end IP-based solution to avoid the
problems of non-interoperable networks interconnected by protocol
translation gateways and proxies. In addition, L2Ns have specific routing
requirements that are not currently met by existing routing protocols, su=
ch
as OSPF, IS-IS, AODV, and OLSR. L2N path selection must be designed to ta=
ke
into consideration the specific power, capabilities, attributes and
functional characteristics of the links and nodes in the network.


There is a wide scope of application areas for L2Ns, including industrial
monitoring, building automation (HVAC, lighting/access control), connecte=
d
home, healthcare, environmental monitoring, agricultural, smart cities,
logistics, assets tracking, and refrigeration. The L2N WG will focus on
routing solutions for a subset of these deployment scenarios, namely
industrial, connected home/building and urban applications. The Working
Group will determine the routing requirements for these scenarios.


The Working Group will provide a routing framework for these application
scenarios that provides high reliability in the presence of time varying
loss characteristics and connectivity while permitting low-power operatio=
n
with very modest memory and CPU pressure.


The Working Group will pay a particular attention to routing security and
manageability (e.g self managing/configuration) issues, which are
particularly critical for L2Ns.

Work Items:

- Produce use cases documents for Industrial, Connected Home, Building an=
d
urban application networks. Each document will describe the use case and =
the
associated routing protocol requirements. The documents will progress in
collaboration with the 6lowpan Working Group (INT area).


- Survey the applicability of existing protocols to L2Ns. The aim of this
document will be to analyze the scaling and characteristics of existing
protocols and identify whether or not they meet the routing requirements =
of
the L2Ns applications identified above. Existing IGPs, MANET, NEMO, DTN
routing protocols will be part of evaluation.

- Specification of routing metrics used in path calculation. This include=
s
static and dynamic link/nodes attributes required for routing in L2Ns.

- Provide an architectural framework for routing and path selection at La=
yer
3 (Routing for L2N Architecture)
* Decide whether the L2Ns routing protocol require a distributed,
centralized path computation models or both.
* Decide whether the L2N routing protocol requires a hierarchical routing
approach.

- Produce a security framework for routing in L2Ns.

Goals And Milestones:


April 2008 Submit Use case/Routing requirements for Industrial, Connected
Home, Building and Urban networks applications to the IESG to be consider=
ed
as an Informational RFC.

August 2008: Submit Routing metrics for L2Ns document to the IESG to be
considered as an Informational RFC.

September 2008: Submit first draft of the Routing for L2Ns Architecture
document  (summary of requirements, path computation model,
flat/hierarchy,=A9).

November 2008: Submit Protocol Survey to the IESG to be considered as an
Informational RFC.

January 2009 Submit Security Framework for L2Ns to the IESG to be conside=
red
as an Informational RFC

February 2009: Submit the Routing for L2Ns Architecture document  (summar=
y
of requirements, metrics and attributes, path selection model) to the IES=
G
as an Informational RFC.

March 2009: Recharter.


Please comment/suggest/...

See you in Vancouver.

JP and David.

Hi Kris:

For your question on ESP, AFAIK, RFC 4294 only mandates NULL encryption =
and authentication for interoperability reasons.=20

On the general question of RFC 4294 itself: I'm not sure the work was =
ever done. I hope someone from the list can help?

If the answer is unclear, and considering that we are re-chartering the =
group, maybe we could have a work item to specify the instantiation of =
RFC 4294 for LoWPAN nodes?

Pascal

Is there an email thread somewhere that discusses the impact on 6LoWPAN =

My first quick readthrough makes me very uncomfortable that some of the =
mandates are going to be ugly from a header standpoint.

Hi JP:

Thanks a bunch for this charter. I'll try not to rephrase what was =
already discussed with Christian, Anders, Philip and Misha.=20

There's an additional item I'd wish to see either in ROLL or 6LoWPAN and =
I do not know exactly where it belongs, maybe both. The question is =
whether we need to and can document how RFC 4294 applies for sensors, =
and M2M devices in general, whether they act as hosts or as routers.=20

I've seen IPv6 presented as a Pandora box that drags just too much stuff =
to be incorporated in a sensory device. For instance, at the moment, =
SP100.11a endorses 6LoWPAN formats but it's not so clear at all that =
IPv6 itself is mandated. A clear spec with well-documented =
implementation could be a formidable tool to despond to Fear, =
Uncertainty and Defiance.

So maybe we do not need DHCP (a MAY in RFC 4294) and maybe can do =
without multicast at all if ND is supported some other way (such as =
suggested in: =
http://www.ietf.org/internet-drafts/draft-thubert-lowpan-backbone-router-=
00.txt). Maybe NULL encryption and authentication is enough etc, etc...
=20
Being able to define one minimum set and maybe a few other profiles for =
the use cases that we selected could help tremendously.=20

Otherwise I find the charter real well written and easy to digest. From =
the MANEMO experience, I expect that some arguments about the relative =
applicability of existing MANET protocols will be difficult to prove =
without some good simulation work running agreed-upon scenarios.

Finally, I'm a bit confused that it seems that both IPv4 and IPv6 seem =
supported. Ipv4 comes with a lot of overhead like DHCP. I suggest that =
when trouble comes and things can not be done in a common fashion for =
both IP protocols, hen we prioritize IPv6.

Unfortunately, I can not make it to Vancouver, but I do feel that the =
work is really needed so please count my vote in for the adoption of the =
WG.

Cheers,

Pascal

Subject: [RSN] Here is the new RL2N Proposed Working Charter

Dear all,

As promised, here is the new proposed Working Group, which reflects the
number of comments/suggestions that we received, the pre-WG consensus, =
...

Thanks to Dave Ward (RTD AD) for his input.

Proposed RL2N WG Charter

Description of Working Group

L2Ns (Low power and Lossy networks) are typically composed of many =
embedded
devices with limited power, memory, and processing resources =
interconnected
by a variety of wireless links, such as IEEE 802.15.4, Bluetooth, Low =
Power
WiFi.

L2Ns are transitioning to an end-to-end IP-based solution to avoid the
problems of non-interoperable networks interconnected by protocol
translation gateways and proxies. In addition, L2Ns have specific =
routing
requirements that are not currently met by existing routing protocols, =
such
as OSPF, IS-IS, AODV, and OLSR. L2N path selection must be designed to =
take
into consideration the specific power, capabilities, attributes and
functional characteristics of the links and nodes in the network.


There is a wide scope of application areas for L2Ns, including =
industrial
monitoring, building automation (HVAC, lighting/access control), =
connected
home, healthcare, environmental monitoring, agricultural, smart cities,
logistics, assets tracking, and refrigeration. The L2N WG will focus on
routing solutions for a subset of these deployment scenarios, namely
industrial, connected home/building and urban applications. The Working
Group will determine the routing requirements for these scenarios.


The Working Group will provide a routing framework for these application
scenarios that provides high reliability in the presence of time varying
loss characteristics and connectivity while permitting low-power =
operation
with very modest memory and CPU pressure.


The Working Group will pay a particular attention to routing security =
and
manageability (e.g self managing/configuration) issues, which are
particularly critical for L2Ns.

Work Items:

- Produce use cases documents for Industrial, Connected Home, Building =
and
urban application networks. Each document will describe the use case and =
the
associated routing protocol requirements. The documents will progress in
collaboration with the 6lowpan Working Group (INT area).


- Survey the applicability of existing protocols to L2Ns. The aim of =
this
document will be to analyze the scaling and characteristics of existing
protocols and identify whether or not they meet the routing requirements =
of
the L2Ns applications identified above. Existing IGPs, MANET, NEMO, DTN
routing protocols will be part of evaluation.

- Specification of routing metrics used in path calculation. This =
includes
static and dynamic link/nodes attributes required for routing in L2Ns.

- Provide an architectural framework for routing and path selection at =
Layer
3 (Routing for L2N Architecture)
* Decide whether the L2Ns routing protocol require a distributed,
centralized path computation models or both.
* Decide whether the L2N routing protocol requires a hierarchical =
routing
approach.

- Produce a security framework for routing in L2Ns.

Goals And Milestones:


April 2008 Submit Use case/Routing requirements for Industrial, =
Connected
Home, Building and Urban networks applications to the IESG to be =
considered
as an Informational RFC.

August 2008: Submit Routing metrics for L2Ns document to the IESG to be
considered as an Informational RFC.

September 2008: Submit first draft of the Routing for L2Ns Architecture
document  (summary of requirements, path computation model,
flat/hierarchy,=A9).

November 2008: Submit Protocol Survey to the IESG to be considered as an
Informational RFC.

January 2009 Submit Security Framework for L2Ns to the IESG to be =
considered
as an Informational RFC

February 2009: Submit the Routing for L2Ns Architecture document  =
(summary
of requirements, metrics and attributes, path selection model) to the =
IESG
as an Informational RFC.

March 2009: Recharter.


Please comment/suggest/...

See you in Vancouver.

JP and David.

This does not surprise me that much.
Why would you want to expend the overhead of an ESP encapsulation to  
provide no security whatsoever?

Dear Pascal and JP,

I'm very happy to see the same thought of me on RFC 4294.
I agree on JP that this work is more on 6LoWPAN in general
and RL2N (or ROLL - I like this idea ^^) can check it in routing
perspective, if any.

I once discussed with Carsten about the necessity of this issue.
I've discussed this matter with some other Korean developers from
sensor node companies. We quite agreed on the necessity, and I and my
colleagues already proposed this work as korean domestic standard
first. The proposal has been accepted, and korean experts will start
to discuss it more to develop domestic standard. It must be great if
we can discuss it with IETF experts as well.

Pascal, I think it would be good if we can check each other's
profiling and collaborate to make one profile based on them. :)

I had missed that; Seems that we have to make an exception :) If you =
consider ISA100.11a, they already have security at L2 and L5, it makes =
little sense to MUST IPSec on top of that.

>> Proposed RL2N WG Charter
>>
>> Description of Working Group
>>
>> L2Ns (Low power and Lossy networks) are typically composed of many =
embedded
>> devices with limited power, memory, and processing resources =
interconnected
>> by a variety of wireless links, such as IEEE 802.15.4, Bluetooth, Low =
Power
>> WiFi.
>>
>> L2Ns are transitioning to an end-to-end IP-based solution to avoid =
the
>> problems of non-interoperable networks interconnected by protocol
>> translation gateways and proxies. In addition, L2Ns have specific =
routing
>> requirements that are not currently met by existing routing =
protocols, such
>> as OSPF, IS-IS, AODV, and OLSR. L2N path selection must be designed =
to take
>> into consideration the specific power, capabilities, attributes and
>> functional characteristics of the links and nodes in the network.
>>
>>
>> There is a wide scope of application areas for L2Ns, including =
industrial
>> monitoring, building automation (HVAC, lighting/access control), =
connected
>> home, healthcare, environmental monitoring, agricultural, smart =
cities,
>> logistics, assets tracking, and refrigeration. The L2N WG will focus =
on
>> routing solutions for a subset of these deployment scenarios, namely
>> industrial, connected home/building and urban applications. The =
Working
>> Group will determine the routing requirements for these scenarios.
>>
>>
>> The Working Group will provide a routing framework for these =
application
>> scenarios that provides high reliability in the presence of time =
varying
>> loss characteristics and connectivity while permitting low-power =
operation
>> with very modest memory and CPU pressure.
>>
>>
>> The Working Group will pay a particular attention to routing security =
and
>> manageability (e.g self managing/configuration) issues, which are
>> particularly critical for L2Ns.
>>
>> Work Items:
>>
>> - Produce use cases documents for Industrial, Connected Home, =
Building and
>> urban application networks. Each document will describe the use case =
and the
>> associated routing protocol requirements. The documents will progress =
in
>> collaboration with the 6lowpan Working Group (INT area).
>>
>>
>> - Survey the applicability of existing protocols to L2Ns. The aim of =
this
>> document will be to analyze the scaling and characteristics of =
existing
>> protocols and identify whether or not they meet the routing =
requirements of
>> the L2Ns applications identified above. Existing IGPs, MANET, NEMO, =
DTN
>> routing protocols will be part of evaluation.
>>
>> - Specification of routing metrics used in path calculation. This =
includes
>> static and dynamic link/nodes attributes required for routing in =
L2Ns.
>>
>> - Provide an architectural framework for routing and path selection =
at Layer
>> 3 (Routing for L2N Architecture)
>> * Decide whether the L2Ns routing protocol require a distributed,
>> centralized path computation models or both.
>> * Decide whether the L2N routing protocol requires a hierarchical =
routing
>> approach.
>>
>> - Produce a security framework for routing in L2Ns.
>>
>> Goals And Milestones:
>>
>>
>> April 2008 Submit Use case/Routing requirements for Industrial, =
Connected
>> Home, Building and Urban networks applications to the IESG to be =
considered
>> as an Informational RFC.
>>
>> August 2008: Submit Routing metrics for L2Ns document to the IESG to =
be
>> considered as an Informational RFC.
>>
>> September 2008: Submit first draft of the Routing for L2Ns =
Architecture
>> document  (summary of requirements, path computation model,
>> flat/hierarchy,=A9).
>>
>> November 2008: Submit Protocol Survey to the IESG to be considered as =
an
>> Informational RFC.
>>
>> January 2009 Submit Security Framework for L2Ns to the IESG to be =
considered
>> as an Informational RFC
>>
>> February 2009: Submit the Routing for L2Ns Architecture document  =
(summary
>> of requirements, metrics and attributes, path selection model) to the =
IESG
>> as an Informational RFC.
>>
>> March 2009: Recharter.

Pascal,
      There will be a presentation in 6MAN on a possible update to 4294 
to address other changes in the standards.  I would encourage people 
interested in including sensor-like devices in such an update to bring 
the topic up either in the 6MAN meeting in Vancouver, on the 6MAN 
mailing list, or to the author of 4294 (John Loughney).

Regards,
Brian

I will search back, but m recollection was that we (you) did argue with
the IESG that devices such as these (small 8bit micro sensors) would not
be capable of IPsec and after a few emails back a forth we were told
that 6lowpan devices did not need to support IPsec.

Again I will look back and see if I can find the email exchange and I'll
ask Russ.

Hi Geoff:

It's not just about IPSec though:

There are a number of companies out there designing and integrating =
silicon for LoWPANs. IPv6 is not necessarily a target for them when it =
does not mean immediate sales. Also, they do not necessarily know what =
supporting IPv6 means for their devices and what the associated cost =
will be. They could use some help and we can provide it in the form of =
an RFC that summarizes a LoWPAN profile for IPv6.=20

That profile should not include IPSec; that profile should include =
6LoWPAN - RFC 4944 is not listed in RFC 4294 for obvious reasons-, and =
the ND solution we will come up with. That profile should be designed to =
enable very low end embedded systems (an 8-bit processor in my Mc D's =
toy) to run IPv6.

Once we have that published with IETF stamp of approval, it becomes =
possible for people out there to:

- guarantee interoperability
- develop and distribute an opensource stack
- publish actual numbers for footprint and performance on various =
implementations
- go to standard bodies such as ISA SP100 and present those numbers to =
support IPv6 adoption.

I do think it is worth the effort. If 6MAN is the place, so be it.

Pascal
