A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Performance Metrics Working Group of the IETF.

	Title		: Packet Reordering Metric for IPPM
	Author(s)	: A. Morton
	Filename	: draft-ietf-ippm-reordering-04.txt
	Pages		: 25
	Date		: 2003-11-4
	
This memo defines a simple metric to determine if a network has
maintained packet order. It provides motivations for the new metric,
gives the metric definition, and discusses the issues associated
with its measurement. The memo defines additional sample metrics to
quantify the extent of reordering in several useful dimensions. Some
examples of evaluation using the various sample metrics are
included.

We finally got this announced and posted, it was more fun than usual.
Thanks to our Chairs for their help.

One of the Action Items from the last meeting was to prepare
some text on fragmentation.  I put this together as an Appendix,
because it's two pages long and would interrupt the flow.
I also held it out of the 04 version, seeking simplifications
over time but with minimal success.  Suggestions welcome.

Al

13. Appendix on fragment order evaluation

    Section 3 stated that fragment re-assembly is assumed prior to order
    evaluation, but that similar procedures could be applied prior to
    re-assembly.  This appendix gives definitions and procedures to
    identify reordering in a packet stream that includes fragmentation.

    The Metric retains the same name, Type-P-reordered, but additional
    parameters are required.

13.1 Additional Metric Parameters:

    +  MoreFrag, the state of the More Fragments Flag in the IP header

    +  FragOffset, the offset from the beginning of a fragmented packet,
      in 8 octet units (also from the IP header).

    +  FragSeq#, the sequence number from the IP header of a fragmented
      packet currently under evaluation for reordering. When set to
      zero, fragment evaluation is not in progress.

    +  NextExpFrag, the Next Expected Fragment Offset at the
      Destination, in 8 octet units. Set to zero when fragment evaluation
      is not in progress.

    The packet sequence number, s, is assumed to be the same as the IP
    header sequence number. Also, the value of NextExp does not change
    with the in-order arrival of fragments. NextExp is only updated when
    a last fragment or a complete packet arrives.

    Note that packets with missing fragments MUST be declared lost, and
    the Reordering status of any fragments that do arrive MUST be
    excluded from sample metrics.

13.2 Definition:

    The value of Type-P-Reordered is typically false (the packet is in-
    order) when

    * the sequence number s >= NextExp,

    * AND the fragment offset FragOffset >= NextExpFrag

    However, it more efficient to define reordered conditions exactly,
    and designate Type-P-Reordered as False otherwise.

    The value of Type-P-Reordered is defined as True (the packet is
    reordered) under the conditions below. In these cases, the NextExp
    value does not change.

    Case 1: if s < NextExp

    Case 2: if s>= NextExp AND s < FragSeq#

    Case 3: if s>= NextExp AND s = FragSeq# AND FragOffset < NextExpFrag

    This definition can also be illustrated in pseudo-code. An early
    draft version of the code follows, and simplification may be
    possible. The challenging aspect surrounds the housekeeping for the
    new parameters.

    NextExp=0;
    NextExpFrag=0;
    FragSeq#=0;

    while(packets arrive with s, MoreFrag, FragOffset)
    {
    if (s>=NextExp AND MoreFrag==0){
         /* a normal packet or the last fragment of a packet arrived */
         NextExp = s+1;
         FragSeq# = 0;
         NextExpFrag = 0;
         Reordering = False;
         }
    if (s>=NextExp AND MoreFrag==1 AND s>FragSeq#>=0){
         /* a fragment of a new packet arrived, possibly with a
         higher sequence number than the current fragmented packet */
         FragSeq# = s;
         NextExpFrag = FragOffset+1;
         Reordering = False;
         }
    if (s>=NextExp AND MoreFrag==1 AND s==FragSeq#){
         /* a fragment of the "current packet s" arrived */
         if (FragOffset >= NextExpFrag){
                 NextExpFrag = FragOffset+1;
                 Reordering = False;
                 }
         else{
                 Reordering = True; /* fragment reordered  */
                 }
         }
    if (s>=NextExp AND MoreFrag==1 AND s < FragSeq#){
         /* case where a late fragment arrived */
         Reordering = True;
         }
    else { /* when s < NextExp */
         Reordering = True;
         }
    }

    A working version of the code would include a check to ensure that
    all fragments of a packet arrive before using the Reordered status
    further, such as in sample metrics.

13.3 Notes on Sample Metrics

    All fragments with the same Source Sequence Number are assigned the
    same Source Time.

    Evaluation with byte stream numbering may be simplified if the
    fragment offset is simply added to the SourceByte of the first
    packet (with fragment offset = 0), keeping the 8 octet units of
    the offset in mind.

We finally got this announced and posted, it was more fun than usual.
Thanks to our Chairs for their help.

One of the Action Items from the last meeting was to prepare
some text on fragmentation.  I put this together as an Appendix,
because it's two pages long and would interrupt the flow.
I also held it out of the 04 version, seeking simplifications
over time but with minimal success.  Suggestions welcome.

Al

13. Appendix on fragment order evaluation

    Section 3 stated that fragment re-assembly is assumed prior to order
    evaluation, but that similar procedures could be applied prior to
    re-assembly.  This appendix gives definitions and procedures to
    identify reordering in a packet stream that includes fragmentation.

    The Metric retains the same name, Type-P-reordered, but additional
    parameters are required.

13.1 Additional Metric Parameters:

    +  MoreFrag, the state of the More Fragments Flag in the IP header

    +  FragOffset, the offset from the beginning of a fragmented packet,
      in 8 octet units (also from the IP header).

    +  FragSeq#, the sequence number from the IP header of a fragmented
      packet currently under evaluation for reordering. When set to
      zero, fragment evaluation is not in progress.

    +  NextExpFrag, the Next Expected Fragment Offset at the
      Destination, in 8 octet units. Set to zero when fragment evaluation
      is not in progress.

    The packet sequence number, s, is assumed to be the same as the IP
    header sequence number. Also, the value of NextExp does not change
    with the in-order arrival of fragments. NextExp is only updated when
    a last fragment or a complete packet arrives.

    Note that packets with missing fragments MUST be declared lost, and
    the Reordering status of any fragments that do arrive MUST be
    excluded from sample metrics.

13.2 Definition:

    The value of Type-P-Reordered is typically false (the packet is in-
    order) when

    * the sequence number s >= NextExp,

    * AND the fragment offset FragOffset >= NextExpFrag

    However, it more efficient to define reordered conditions exactly,
    and designate Type-P-Reordered as False otherwise.

    The value of Type-P-Reordered is defined as True (the packet is
    reordered) under the conditions below. In these cases, the NextExp
    value does not change.

    Case 1: if s < NextExp

    Case 2: if s>= NextExp AND s < FragSeq#

    Case 3: if s>= NextExp AND s = FragSeq# AND FragOffset < NextExpFrag

    This definition can also be illustrated in pseudo-code. An early
    draft version of the code follows, and simplification may be
    possible. The challenging aspect surrounds the housekeeping for the
    new parameters.

    NextExp=0;
    NextExpFrag=0;
    FragSeq#=0;

    while(packets arrive with s, MoreFrag, FragOffset)
    {
    if (s>=NextExp AND MoreFrag==0){
         /* a normal packet or the last fragment of a packet arrived */
         NextExp = s+1;
         FragSeq# = 0;
         NextExpFrag = 0;
         Reordering = False;
         }
    if (s>=NextExp AND MoreFrag==1 AND s>FragSeq#>=0){
         /* a fragment of a new packet arrived, possibly with a
         higher sequence number than the current fragmented packet */
         FragSeq# = s;
         NextExpFrag = FragOffset+1;
         Reordering = False;
         }
    if (s>=NextExp AND MoreFrag==1 AND s==FragSeq#){
         /* a fragment of the "current packet s" arrived */
         if (FragOffset >= NextExpFrag){
                 NextExpFrag = FragOffset+1;
                 Reordering = False;
                 }
         else{
                 Reordering = True; /* fragment reordered  */
                 }
         }
    if (s>=NextExp AND MoreFrag==1 AND s < FragSeq#){
         /* case where a late fragment arrived */
         Reordering = True;
         }
    else { /* when s < NextExp */
         Reordering = True;
         }
    }

    A working version of the code would include a check to ensure that
    all fragments of a packet arrive before using the Reordered status
    further, such as in sample metrics.

13.3 Notes on Sample Metrics

    All fragments with the same Source Sequence Number are assigned the
    same Source Time.

    Evaluation with byte stream numbering may be simplified if the
    fragment offset is simply added to the SourceByte of the first
    packet (with fragment offset = 0), keeping the 8 octet units of
    the offset in mind.

Dear,

In the IPPM WG I am in charge of the
draft-ietf-ippm-metrics-registry-04.txt.
The WG document draft-ietf-ippm-metrics-registry-04.txt disappeared from
the web page of the IPPM WG and from the internet draft list too.

Is it due to some mistake ?=20

Regards
Emile

This document describes a framework of a new scheme for traffic
control to achieve end-to-end QoS for interactive multimedia
services.  The scheme is based on end-to-end measurement of network
resources by end systems.  The network is assumed to fully support
the priority control scheme specified in the Diffserv architecture
for QoS and SIP [1]  for session control.  Since the scheme relies on
the behavior of the end systems, this document also touches on
mechanisms for monitoring end-system behavior.

interactive multimedia services by exercising admission control for a
series of packets on a packet-based network.  The scheme is based on
the end-to-end measurement of network resources by end systems.  The
destination end system notifies the conditions of receipt for a
limited set of packets sent from the source end.  If this is
acceptable, the source end system then promotes the priority of the
succeeding IP packets to firmly establish the session.  The network
is only assumed to support a per-class form of priority control,
since this allows the end systems to measure remaining resources
without affecting the existing streams.  If all end systems behave in
the above way, we can achieve specific levels of end-to-end QoS
without maintaining per-flow states in each item of network equipment.

realizable by elaborating configurations of existing equipment.

	Dear,

	I don't see anymore the draft
draft-ietf-ippm-metrics-registry-04.txt on the web page of the IPPM WG.
It looks like it expired.
	So this is the version 5 of the ippm metrics registry:
draft-ietf-ippm-metrics-registry-05.txt

> This memo defines a registry of the IPPM working group metrics. It
> assigns an OBJECT IDENTIFIER to each metric currently standardized by
> the IPPM WG. It defines the rules for the identification of the
> metrics standardized in the future.
>=20

	Dear,

	I don't see anymore the draft
draft-ietf-ippm-metrics-registry-04.txt on the web page of the IPPM WG.
It looks like it expired.
	So this is the version 5 of the ippm metrics registry:
draft-ietf-ippm-metrics-registry-05.txt

> This memo defines a registry of the IPPM working group metrics. It
> assigns an OBJECT IDENTIFIER to each metric currently standardized by
> the IPPM WG. It defines the rules for the identification of the
> metrics standardized in the future.
>=20

Yes, there is at least 1 other draft that got dropped as well.  We'll
sort this out, not sure if we can do this before MPLS.

Dear Henk,

As the document draft-ietf-ippm-metrics-registry-04.txt is not obsolete =
the secretary should make the correction by itself before the RMON WG =
session of this evening.

Regards
Emile

Dear Dinara,

Actually the version 04 was updated by Matt in June (see below). It =
looks like that the expiration process has not checked the date of the =
file itself. This document is less than 6 months old.

This document creation was initially requested by the RMON WG. So I =
would be glad if you may put back the document in the internet draft =
list and on the WEB page of the IPPM WG before Monday noon (day of the =
RMON session).

There is still something I am missing. Why the version 4 draft was not =
replaced with the same kind of file (see =
draft-ietf-ippm-metrics-registry-05.txt attached) telling that it =
expired ?

Regards
Emile=20

All,

Right now, I see 5 drafts:

  1. A One-way Active Measurement Protocol (OWAMP)  (86233 bytes)
  2. A One-way Active Measurement Protocol Requirements (21551 bytes)
  3. IPPM metrics registry (675 bytes)
  4. IPPM reporting MIB (158332 bytes)
  5. Packet Reordering Metric for IPPM (56012 bytes)

3 looked a bit short and is indeed only a note that it expired.  Emile, =
please resubmit after MPLS.  Missing is the Colorado draft on reordering =
(or is that still an individual submission?).

In the latter case, we should discuss if/how this should become a WG =
item on Thu.

Any other ID's that I missed?

Henk

Dear Henk,

As the document draft-ietf-ippm-metrics-registry-04.txt is not obsolete =
the secretary should make the correction by itself before the RMON WG =
session of this evening.

Regards
Emile

Dear Dinara,

Actually the version 04 was updated by Matt in June (see below). It =
looks like that the expiration process has not checked the date of the =
file itself. This document is less than 6 months old.

This document creation was initially requested by the RMON WG. So I =
would be glad if you may put back the document in the internet draft =
list and on the WEB page of the IPPM WG before Monday noon (day of the =
RMON session).

There is still something I am missing. Why the version 4 draft was not =
replaced with the same kind of file (see =
draft-ietf-ippm-metrics-registry-05.txt attached) telling that it =
expired ?

Regards
Emile=20

All,

> that the registry draft did not expire, either...

Right now, I see 5 drafts:

  1. A One-way Active Measurement Protocol (OWAMP)  (86233 bytes)
  2. A One-way Active Measurement Protocol Requirements (21551 bytes)
  3. IPPM metrics registry (675 bytes)
  4. IPPM reporting MIB (158332 bytes)
  5. Packet Reordering Metric for IPPM (56012 bytes)

3 looked a bit short and is indeed only a note that it expired.  Emile, =
please resubmit after MPLS.  Missing is the Colorado draft on reordering =
(or is that still an individual submission?).

In the latter case, we should discuss if/how this should become a WG =
item on Thu.

Any other ID's that I missed?

Henk

Hi,

I know the question is out of scope of this list. But
I do not know where to ask for help, avoid the
question if this make you inconvinence.

Where could I find measurement data set and threshhold
data between two ethernet ports connected by optic
fiber?  

thanks in advance.

1. General comments

Although a good job has been done documenting this MIB,
IMO it is too complex to be deployable.  The resource
requirements in the agent are very large.  Some of the 
tables can get extremely large, which would lead to 
poor SNMP performance.  The resource limitation mechanisms 
do not align well with actual SNMP agent implementation 
constraints.

This MIB is way too complicated and contains too many 
features that should be provided by an EMS or NMS.  There
are likely to be many implementation difficulties due to
undocumented (and unforeseen) interactions between features.
The MIB should be simplified to collect metric values
and provide aggregation reports which can be retrieved
via SNMP.  Analysis of the reports, threshold based
exception handling, sending email and pages to administrators, 
etc. should be left to the application.

2. sec. 3) SNMP Framework

This boilerplate is out of date.
Use the new template at:
http://www.ops.ietf.org/mib-boilerplate.html

3. sec 4, para 4) RMON model

This paragraph is incorrect. RMON can collect data from 
several interfaces which are not required to be in the
same chassis.

4. sec. 4.1.3.1) Internet addresses 

Why are special address types needed for Src and Dest?

5. sec. 4.1.4)   GMTTimeStamp 

Why is it important to start the timestamp from 2000
instead of 1900?  This is extra work since implementations
are likely to support the standard "seconds since 1900"
format, not this new format.

6. sec. 4.1.6)   Report definition 

This TC is very complex and overloads many functions
into a single bit string.  It should be broken out
into several MIB objects for simplicity and clarity.

7. MIB, TypeP TC)

This design is flawed because the authoritative name
of the protocol is based on the descriptive string found
in an RMON protocol identifier.  However this text string
is not normative and not required to be globally unique
or even consistent across implementations.

8. MIB, IppmReportDefinition TC

This TC overloads event management, report filtering,
delivery options, and report cleanup options in a
long bit string.  This should be split into at least 
4 TCs (or MIB objects).

9. MIB, ippmSystemTime object

There should not need to be a special object for the
system time.  Also, how does the NMS know if the probe
is in proxy mode?

10. MIB, Clock sync objects

   ippmSystemSynchronizationType
   ippmSystemSynchronizationDesc
   ippmSystemClockResolution

These objects should be in a separate MIB module
since this is a generic problem not specific to
IPPM reporting.

11. MIB, ippmSynchronizationTable

Why is a history table of up to 64K clock sync events
needed?  This will take up a lot of memory for very
questionable value.  

12. MIB, point of measure table

  IppmPointOfMeasureEntry ::= SEQUENCE { 
   ippmPointOfMeasureIndex                Unsigned32, 
   ippmPointOfMeasureMgmtAddrType         InetAddressType, 
   ippmPointOfMeasureMgmtAddress          InetAddress, 
   ippmPointOfMeasureTestAddrTypeP        TypeP, 
   ippmPointOfMeasureTestAddr             TypePaddress, 
   ippmPointOfMeasureMetrics              IppmStandardMetrics 
  } 

Why is there a management address for each test point?
How is this used?  Why does the NMS need to know this?
Doesn't the NMS just contact the IPPM SNMP agent to
retrieve data?

Why is the test address of the measurement point needed?
Why isn't it an InetAddress?  How is this used?

13. MIB, ippmMetricEntry

This table is broken because there is only one entry per
metric.  This assumes that the collection capabilities
are the same for every point of measure, which is not very
likely.  The ippmPointOfMeasureIndex should be added
(first) to the INDEX clause in this table.

14. MIB, ippmMetricCapabilities

  ippmMetricCapabilities OBJECT-TYPE 
   SYNTAX INTEGER { 
   notImplemented(0), 
   implemented(1) 

Why is this object needed?  Why not just populate the
table for metrics that are implemented.  The other objects
in this table are irrelevant or unknown if the metric is
not implemented by the agent.

15. MIB, ippmOwnersTable

  IppmOwnersEntry ::= SEQUENCE { 
   ippmOwnersIndex              Unsigned32, 
   ippmOwnersOwner              IppmOwnerString, 

The ippmOwnerOwner object is the object that is used
to create unique index values in other tables (e.g.,
that represent history entries), yet this object is
required to be unique in this table.  The ippmOwnersIndex
object has no value at all and should be removed.  This 
table should be indexed by the ippmOwnersOwner object.


16. MIB, owner address

   ippmOwnersIpAddressType      InetAddressType, 
   ippmOwnersIpAddress          InetAddress, 

Why are these objects in the MIB?  Why does it
matter what the owner's address is in this MIB module?
If this is for sending notifications, then use the
MIBs in the SNMP Applications document, not this table.

   ippmOwnersEmail              SnmpAdminString, 
   ippmOwnersSMS                SnmpAdminString, 

These objects should be removed and the functions of
sending IPPM metric reports in email or phone messages
should be removed.  These functions are too complex for an
SNMP agent.  In addition, the format of the email
or SMS is not defined in any way.  This will not be
interoperable in any way.

17. MIB, ippmHistoryTable

This table is very complex and can get very huge, or entries
will be so short-lived that the table will be unstable and
very difficult to retrieve.  Keeping a timestamp and value
for every metric value collected by the probe is overkill.

18. MIB, ippmHistorySequence

       Network metrics:  
       It's the sequence number of a measurement packet. Typically, it 
       identifies the order of the packet in the stream of packets sent 
       by the source. 
        
       Aggregated metrics: 
       It is the sequence number of the computed aggregated metric 
       result." 

Why is this object useful if the table already has an
index for the measure instance?  Why is an additional
index for the packet sequence needed?  What if the
entry is for a metric that utilizes more than one packet
in the measurement?

19. MIB, ippmHistoryValue
   SYNTAX Integer32 

Why is this an Integer32 instead of Unsigned32?
Could it ever be a negative number?

20. MIB, ippmNetMeasureTable

       " The IppmNetMeasureTable is mandatory, and its content is read 
       only. It means that the measurement software handles the table 
       internally. The setup of the network measure is not permitted 
       through the IPPM REPORTING MIB. As an example, OWAP provides a 
       setup protocol to setup and tear down networks measures. 

This goes entirely against the spirit of SNMP to contain
a configuration table that is populated in an unspecified
manner, and not allowing SNMP to be used for configuration.
These objects should be read-create with a MIN-ACCESS of
read-only.

Also, this MIB should not include this table because this 
table indicates the configuration of test traffic generators.  
The comments in the previous paragraph apply to the MIB module 
that is eventually used for traffic generation.  The 
Synthetic Sources for Performance Measurements MIB (SSPM-MIB) 
should be used for this purpose.

The status and statistics objects in this table should
be split out and placed in another table.  That table 
may be appropriate for this MIB module.

21. MIB, IppmAggrMeasureEntry

   ippmAggrMeasureOwner                  IppmOwnerString, 
   ippmAggrMeasureIndex                  Unsigned32, 
   ippmAggrMeasureName                   SnmpAdminString, 
   ippmAggrMeasureMetrics                IppmStandardMetrics, 
   ippmAggrMeasureBeginTime              GMTTimeStamp, 
   ippmAggrMeasureAggrPeriodUnit         TimeUnit, 
   ippmAggrMeasureAggrPeriod             Unsigned32, 
   ippmAggrMeasureDurationUnit           TimeUnit, 
   ippmAggrMeasureDuration               Unsigned32, 
   ippmAggrMeasureHistorySize            Unsigned32, 
   ippmAggrMeasureStorageType            StorageType, 
   ippmAggrMeasureHistoryOwner           IppmOwnerString, 
   ippmAggrMeasureHistoryOwnerIndex      Unsigned32, 
   ippmAggrMeasureHistoryMetric          Unsigned32, 
   ippmAggrMeasureAdminState             INTEGER, 
   ippmAggrMeasureFastReport             OBJECT IDENTIFIER, 
   ippmAggrMeasureMap                    SnmpAdminString, 
   ippmAggrMeasureResultsMgmt            INTEGER, 
   ippmAggrMeasureLastUpdate             GMTTimeStamp, 
   ippmAggrMeasureOperState              INTEGER, 
   ippmAggrMeasureNbPktsTreated          Counter64, 
   ippmAggrMeasureStatus                 RowStatus 

This configuration table is rather complex.
The ippmAggrMeasureName object is redundant, since
this info is already available in another table.
Recording this long string in every entry is wasteful.

The ippmAggrMeasureHistoryOwner object makes this too complex.
The same value for the owner in this table and the history
table should be used.

The ippmAggrMeasureHistoryMetric object is confusing.  How does
it relate to the ippmAggrMeasureMetrics object in this table?

It is not clear why the ippmAggrMeasureAdminState object
is needed and what it means to start or stop this entry
at any time.

The ippmAggrMeasureFastReport object is complex and
it is not clear what value it adds.  Why is this needed
and ippmReport needed?

22. MIB, ippmAggrMeasureMap
   SYNTAX SnmpAdminString 
   MAX-ACCESS read-create 
   STATUS     current 
   DESCRIPTION 
       "This object allows for classification of the measure. It is 
       typically the name of an administrative map. 

I have no idea what this object is for.  There are no
guidelines for populating this object and therefore
no interoperability possible.

23. MIB, ippmReportPathToResults 

This URL object is a global scalar, which is odd since
multiple reports for multiple owners are created.
Why are results pushed off the box to a file?  What is
the format of this file?  Just SNMP access should be
provided.

24. MIB, IppmReportSetupEntry

This table sets up a report but it looks like each entry
represents one metric.  This seems broken since the
parameters would be the same for each metric collected
in the set (IppmStandardMetrics OCTET STRING).  A different
complex report configuration for each metric is too
complicated.  Since some metrics are related to each
other, it doesn't really make sense to have a report
for each metric.  It would be much better to have
one report for each set of metrics collected.

25. MIB, ippmReportSetupMeasureOwner

Why is this object needed?  This is too complex. Any type
of access control should be done by VACM, not by matching
values of IppmOwnerStrings. Just the integer index pointer
is needed.

26. MIB, thresholding objects in this table

This thresholding mechanism is too complex and too generic 
to be included in this table. 

27. MIB, ippmReportSetupNMS
   DESCRIPTION 
       "The recipient of the report may be provided in the setup. By 

This object is not needed.  SNMP should be used to retrieve data
and other MIBs exist to determine where to send notifications.

28. MIB, ippmReportSetupNotification
   SYNTAX     OBJECT IDENTIFIER 
   MAX-ACCESS read-create 
   STATUS     current 
   DESCRIPTION 
       "Even though the notification to use is defined in the report 
       definition, the object ippmReportSetupNotification provides 
       flexibility to select another notification. " 
   DEFVAL { zeroDotZero } 

This object is too vague and there is no chance for 
interoperability.  This is also too complicated on the agent
to be told by the NMS which notification to generate
for each report.

29. MIB, ippmReportSetupMap
   DESCRIPTION 
       "An administrative name of a map to which the report belongs." 

This object is too vague and has no chance for
interoperability. It should be removed.

30. MIB, ippmReportEntry

This table doesn't seem to add much value beyond the
history table.  It is also too complicated to have
separate results for every metric collected in a
report.  How are all metrics collected for a given
report correlated?  The network and aggregated features
seem too complicated and are not well defined.
A single report for all metrics collected together for
a given test should be provided instead.

31. MIB, ippmReportValue
   SYNTAX Integer32 
   MAX-ACCESS read-only 
   STATUS     current 
   DESCRIPTION 
       "The value." 

Why is this object an Integer32 instead of Unsigned32?
The description is not very useful.

32. MIB, Notifications

It is not very clear the exact conditions and configuration
used by the agent to decide when to send each notification.
It is not very clear why so many different notification types
are needed.  All notifications include a lot of static info that
is not really needed.

33. Security considerations

Very good security section!

1. General comments

Although a good job has been done documenting this MIB,
IMO it is too complex to be deployable.  The resource
requirements in the agent are very large.  Some of the 
tables can get extremely large, which would lead to 
poor SNMP performance.  The resource limitation mechanisms 
do not align well with actual SNMP agent implementation 
constraints.

This MIB is way too complicated and contains too many 
features that should be provided by an EMS or NMS.  There
are likely to be many implementation difficulties due to
undocumented (and unforeseen) interactions between features.
The MIB should be simplified to collect metric values
and provide aggregation reports which can be retrieved
via SNMP.  Analysis of the reports, threshold based
exception handling, sending email and pages to administrators, 
etc. should be left to the application.

2. sec. 3) SNMP Framework

This boilerplate is out of date.
Use the new template at:
http://www.ops.ietf.org/mib-boilerplate.html

3. sec 4, para 4) RMON model

This paragraph is incorrect. RMON can collect data from 
several interfaces which are not required to be in the
same chassis.

4. sec. 4.1.3.1) Internet addresses 

Why are special address types needed for Src and Dest?

5. sec. 4.1.4)   GMTTimeStamp 

Why is it important to start the timestamp from 2000
instead of 1900?  This is extra work since implementations
are likely to support the standard "seconds since 1900"
format, not this new format.

6. sec. 4.1.6)   Report definition

8. MIB, IppmReportDefinition TC

This TC overloads event management, report filtering,

4 TCs (or MIB objects).

9. MIB, ippmSystemTime object

There should not need to be a special object for the
system time.  Also, how does the NMS know if the probe

10. MIB, Clock sync objects

   ippmSystemSynchronizationType
   ippmSystemSynchronizationDesc

These objects should be in a separate MIB module
since this is a generic problem not specific to
IPPM reporting.

11. MIB, ippmSynchronizationTable

Why is a history table of up to 64K clock sync events
needed?  This will take up a lot of memory for very
questionable value.  

12. MIB, point of measure table

  IppmPointOfMeasureEntry ::= SEQUENCE { 
   ippmPointOfMeasureIndex                Unsigned32, 
   ippmPointOfMeasureMgmtAddrType         InetAddressType,

   ippmPointOfMeasureTestAddrTypeP        TypeP, 
   ippmPointOfMeasureTestAddr             TypePaddress, 
   ippmPointOfMeasureMetrics              IppmStandardMetrics 
  } 

Why is there a management address for each test point?
How is this used?  Why does the NMS need to know this?
Doesn't the NMS just contact the IPPM SNMP agent to
retrieve data?

Why is the test address of the measurement point needed?
Why isn't it an InetAddress?  How is this used?

13. MIB, ippmMetricEntry

This table is broken because there is only one entry per
metric.  This assumes that the collection capabilities

   implemented(1) 

Why is this object needed?  Why not just populate the
table for metrics that are implemented.  The other objects
in this table are irrelevant or unknown if the metric is
not implemented by the agent.

15. MIB, ippmOwnersTable

  IppmOwnersEntry ::= SEQUENCE { 
   ippmOwnersIndex              Unsigned32, 
   ippmOwnersOwner              IppmOwnerString, 

The ippmOwnerOwner object is the object that is used
to create unique index values in other tables (e.g.,
that represent history entries), yet this object is
required to be unique in this table.  The ippmOwnersIndex
object has no value at all and should be removed.  This 
table should be indexed by the ippmOwnersOwner object.


16. MIB, owner address

   ippmOwnersIpAddress          InetAddress, 

Why are these objects in the MIB?  Why does it

   ippmOwnersEmail              SnmpAdminString, 
   ippmOwnersSMS                SnmpAdminString, 

These objects should be removed and the functions of
sending IPPM metric reports in email or phone messages
should be removed.  These functions are too complex for an
SNMP agent.  In addition, the format of the email

   ippmAggrMeasureHistoryOwner           IppmOwnerString, 
   ippmAggrMeasureHistoryOwnerIndex      Unsigned32, 
   ippmAggrMeasureHistoryMetric          Unsigned32, 
   ippmAggrMeasureAdminState             INTEGER, 
   ippmAggrMeasureFastReport             OBJECT IDENTIFIER, 
   ippmAggrMeasureMap                    SnmpAdminString,

   ippmAggrMeasureOperState              INTEGER, 
   ippmAggrMeasureNbPktsTreated          Counter64, 
   ippmAggrMeasureStatus                 RowStatus 

This configuration table is rather complex.
The ippmAggrMeasureName object is redundant, since
this info is already available in another table.
Recording this long string in every entry is wasteful.

The ippmAggrMeasureHistoryOwner object makes this too complex.
The same value for the owner in this table and the history
table should be used.

The ippmAggrMeasureHistoryMetric object is confusing.  How does
it relate to the ippmAggrMeasureMetrics object in this table?

It is not clear why the ippmAggrMeasureAdminState object
is needed and what it means to start or stop this entry
at any time.

The ippmAggrMeasureFastReport object is complex and
it is not clear what value it adds.  Why is this needed
and ippmReport needed?

22. MIB, ippmAggrMeasureMap
   SYNTAX SnmpAdminString 
   MAX-ACCESS read-create 
   STATUS     current 
   DESCRIPTION 
       "This object allows for classification of the measure. It is 
       typically the name of an administrative map. 

I have no idea what this object is for.  There are no
guidelines for populating this object and therefore
no interoperability possible.

23. MIB, ippmReportPathToResults 

This URL object is a global scalar, which is odd since
multiple reports for multiple owners are created.
Why are results pushed off the box to a file?  What is
the format of this file?  Just SNMP access should be
provided.

24. MIB, IppmReportSetupEntry

This table sets up a report but it looks like each entry
represents one metric.  This seems broken since the
parameters would be the same for each metric collected
in the set (IppmStandardMetrics OCTET STRING).  A different
complex report configuration for each metric is too
complicated.  Since some metrics are related to each
other, it doesn't really make sense to have a report
for each metric.  It would be much better to have
one report for each set of metrics collected.

25. MIB, ippmReportSetupMeasureOwner

Why is this object needed?  This is too complex. Any type
of access control should be done by VACM, not by matching
values of IppmOwnerStrings. Just the integer index pointer
is needed.

26. MIB, thresholding objects in this table

This thresholding mechanism is too complex and too generic 
to be included in this table. 

27. MIB, ippmReportSetupNMS
   DESCRIPTION 
       "The recipient of the report may be provided in the setup. By 

This object is not needed.  SNMP should be used to retrieve data
and other MIBs exist to determine where to send notifications.

28. MIB, ippmReportSetupNotification
   SYNTAX     OBJECT IDENTIFIER 
   MAX-ACCESS read-create 
   STATUS     current 
   DESCRIPTION 
       "Even though the notification to use is defined in the report 
       definition, the object ippmReportSetupNotification provides 
       flexibility to select another notification. " 
   DEFVAL { zeroDotZero } 

This object is too vague and there is no chance for 
interoperability.  This is also too complicated on the agent
to be told by the NMS which notification to generate
for each report.

29. MIB, ippmReportSetupMap
   DESCRIPTION 
       "An administrative name of a map to which the report belongs." 

This object is too vague and has no chance for
interoperability. It should be removed.

30. MIB, ippmReportEntry

This table doesn't seem to add much value beyond the
history table.  It is also too complicated to have
separate results for every metric collected in a
report.  How are all metrics collected for a given
report correlated?  The network and aggregated features
seem too complicated and are not well defined.
A single report for all metrics collected together for
a given test should be provided instead.

31. MIB, ippmReportValue
   SYNTAX Integer32 
   MAX-ACCESS read-only 
   STATUS     current 
   DESCRIPTION 
       "The value." 

Why is this object an Integer32 instead of Unsigned32?
The description is not very useful.

32. MIB, Notifications

It is not very clear the exact conditions and configuration
used by the agent to decide when to send each notification.
It is not very clear why so many different notification types
are needed.  All notifications include a lot of static info that
is not really needed.

33. Security considerations

Very good security section!

34. References

Check the MIB template for update to SNMP references.

As chair, I'd like to say that Andy's comment below is what
I've heard informally, but no one has to-date posted to the
list.  I'd like to ask others to read the draft, and comment
on the complexity (or any other area) --  do you agree, or
do you think that the current draft is on the right track.

With my chair hat off, I concur with Andy's assessment below.
What I always intended to implement with Surveyor was a simple
scheme to export the basic data types; if there was any complex
manipulation, it would be done by the software playing the role
as a network management system.

A thirty-two bit count of seconds since 1900 will soon wrap.
No comment on the other merits / demerits of this TC.

A thirty-two bit count of seconds since 1900 will soon wrap.
No comment on the other merits / demerits of this TC.

Dear Matt and Andy,

The input I received from Matt was to focus on the implemtation of the =
MIB as an proxy rather than an agent embedded in each probe.

When the IPPM MIB is implemeted as a proxy it is an application on the =
top of the measurement system that makes a first level of aggregation =
for NMS and that provides a SNMP interface to the measurement system.
=20
Collecting results take a lot of place either in Surveyor the IPPM MIB, =
in the RMON MIB or in a IPFIX collector. The rule of the IPPM MIB is to =
make an initial consolidation of the result to avoid to flood NMS =
application with unrelevant information.

FTRD has implemented the proxy on the top of an industrial measurement =
system. I can make a live demo of it during the meeting or after.

Best Regards
Emile

done by the software playing the role as a network management system.

Dear Matt and Andy,

The input I received from Matt was to focus on the implemtation of the =
MIB
as an proxy rather than an agent embedded in each probe.

When the IPPM MIB is implemeted as a proxy it is an application on the =
top
of the measurement system that makes a first level of aggregation for =
NMS
and that provides a SNMP interface to the measurement system.
=20
Collecting results take a lot of place either in Surveyor the IPPM MIB, =
in
the RMON MIB or in a IPFIX collector. The rule of the IPPM MIB is to =
make an
initial consolidation of the result to avoid to flood NMS application =
with
unrelevant information.

FTRD has implemented the proxy on the top of an industrial measurement
system. I can make a live demo of it during the meeting or after.

Best Regards
Emile

As chair, I'd like to say that Andy's comment below is what I've heard
informally, but no one has to-date posted to the list.  I'd like to ask
others to read the draft, and comment on the complexity (or any other =
area)
--  do you agree, or do you think that the current draft is on the =
right
track.

With my chair hat off, I concur with Andy's assessment below. What I =
always
intended to implement with Surveyor was a simple scheme to export the =
basic
data types; if there was any complex manipulation, it would be done by =
the
software playing the role as a network management system.

Emile,

I think that the IPPM MIB document would benefit from a framework =
section explaining in more details the concepts that you and Matt are =
describing in your mails - what are the targets where the MIB is =
expected to run, how you define the relationship between the entities =
that you call proxy, Surveyor, NMS, etc.=20

Regards,

Dan

Also with my chair hat off.

The way I currently see this (and the way that we've implemented this) is
something like:

                       +------+
             /-------- | User |----------------\
          Control      +------+             Control

         +--------+                      +----------+
         | Sender |                      | Receiver |
         +--------+                      +----------+
          |  |                             ^    |
          |  |                             |    |
          |  \--------Measurement ---------/    |
          |                                     |
          V                                     V
        +--------------------------------------------+
        |     Results                                |

              |
              V
        +------------+
        | Processing |

              |
              V
             User


The user requests up a measurement session by sending a control message to
both sender and receiver.  Sender and receiver set up the measurement
using a home-grown mechanism now, perhaps OWAMP-control in the future.
The measurement is done, currently with our own protocol, perhaps
OWAMP-test in the future.  Both sender and receiver record data regarding
the measurement in a file.  After the measurement is over, these files are
pulled to a central point at regular intervals. Here data is processed:
combine what sender and receiver know about a measurement, aggregate,
filter, plot and print on web pages or so, depending on what the user
wants.

The last steps are often done more than once, people tend to aggregate
over short intervals as well as long intervals, make 2 or more plots of
the same data etc.

When talking to users, the biggest issue is that the data is not available
until the file has been written.

A buffer with the data from the last X minutes would solve that.  An
application can then query the buffer and do whatever it wants to do with
the data.  This is where I see a standard format (MIB) and protocol
(SNMP) come in.

What people are not interested in, is a standard way to aggregate and
filter data.  Requirements vary a lot here: time interval, loops over the
data, format (numbers vs a plot), etc, and the one size-fits all approach
doesn't seem right.

Also with my chair hat off.

The way I currently see this (and the way that we've implemented this) is
something like:

                       +------+
             /-------- | User |----------------\
          Control      +------+             Control
             |                                 |
             V                                 V
         +--------+                      +----------+
         | Sender |                      | Receiver |
         +--------+                      +----------+
          |  |                             ^    |
          |  |                             |    |
          |  \--------Measurement ---------/    |
          |                                     |
          V                                     V
        +--------------------------------------------+
        |     Results                                |
        +--------------------------------------------+
              |
              V
        +------------+
        | Processing |
        +------------+
              |
              V
             User


The user requests up a measurement session by sending a control message to
both sender and receiver.  Sender and receiver set up the measurement
using a home-grown mechanism now, perhaps OWAMP-control in the future.
The measurement is done, currently with our own protocol, perhaps
OWAMP-test in the future.  Both sender and receiver record data regarding
the measurement in a file.  After the measurement is over, these files are
pulled to a central point at regular intervals. Here data is processed:
combine what sender and receiver know about a measurement, aggregate,
filter, plot and print on web pages or so, depending on what the user
wants.

The last steps are often done more than once, people tend to aggregate
over short intervals as well as long intervals, make 2 or more plots of
the same data etc.

When talking to users, the biggest issue is that the data is not available
until the file has been written.

A buffer with the data from the last X minutes would solve that.  An
application can then query the buffer and do whatever it wants to do with
the data.  This is where I see a standard format (MIB) and protocol
(SNMP) come in.

What people are not interested in, is a standard way to aggregate and
filter data.  Requirements vary a lot here: time interval, loops over the
data, format (numbers vs a plot), etc, and the one size-fits all approach
doesn't seem right.

Wait a second: Surveyor is only one of the implementations of the
One-way-delay and one-way-loss metrics, there are more implementations.
