We have one question in each draft posed to the working group.
I will post/re-post the questions as needed. IPPM has already
indicated interest to work the two remaining drafts in 2008
(on reflecting octets and individual session control),

Yes, that's what I meant.  Please repost the question and let's see
if people have an opinion.

Murtaza and I are looking for feedback on a question posed
at the last meeting, on the Individual Session control draft.
It was in the last slide of
http://www.ietf.org/proceedings/09mar/slides/ippm-1/ippm-1_files/v3_document.htm

Question for IPPM:

o Authors propose to disallow previous Start/Stop (2,3) commands when this feature is available and selected.
o What does IPPM want to do?
o Points to Consider:
        - Mixing the Start/Stop complicates  ... (lots of things)
        - The old set has no Stop-Ack, so if none is received, ... ?

Len Ciavattone and I would like to hear any comments
on the proposal to revise the test packet format
as part of the Reflect Octets feature.

The draft
http://tools.ietf.org/html/draft-ietf-ippm-twamp-reflect-octets-01
and the slides
http://www.ietf.org/proceedings/09mar/slides/ippm-2/ippm-2_files/v3_document.htm
describe what is proposed.

The benefits of using the new test packet format we concocted are:

 - the problem with asymmetrical sizes of test packets sent in
different directions is solved.
 - the generation of the Reflector to Sender packet is simplified
by shuffling the position of some fields.

This would be an optional feature, which removes the need to
do some complicated padding truncation operations as described
in the draft (needed if we don't adopt this or other new format).

Let us know whet you think,
Al and Len

A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ippm-more-twamp-02.txt Technical Summary The IETF has completed its work on TWAMP - the Two-Way Active Measurement Protocol. This memo describes a simple extension to TWAMP, the option to use different security modes in the TWAMP- Control and TWAMP-Test protocols. Working Group Summary This document was discussed at various IETF meetings in 2008. There was no controversy in the WG process. Consensus was smooth. Document Quality At least 3 vendors are implementing TWAMP. Personnel The document shepherd is Henk Uijterwaal (henk@ripe.net). Lars Eggert (lars.eggert@nokia.com) reviewed the ID for the IESG. RFC Editor Note RFC Editor's Note: Title: OLD More features for TWAMP NEW Mixed Security Mode for TWAMP 5. Security Considerations OLD The extended mixed-mode of operation permits stronger security/ integrity protection on the TWAMP-Control protocol while simultaneously emphasizing accuracy or efficiency on the TWAMP-Test protocol, thus making it possible to increase overall security when compared to the previous options. NEW The extended mixed-mode of operation permits stronger security/ integrity protection on the TWAMP-Control protocol while simultaneously emphasizing accuracy or efficiency on the TWAMP-Test protocol, thus making it possible to increase overall security when compared to the previous options (when resource constraints would have forced less security for TWAMP-Control and unauthenticated TWAMP-Test is not a significant concern).

Morton Filename : draft-ietf-ippm-framework-compagg-08.txt Pages : 17 Date : 2009-06-23 This memo describes a detailed framework for composing and aggregating metrics (both in time and in space) originally defined by the IP Performance Metrics (IPPM) RFC 2330 and developed by the IETF. This new framework memo describes the generic composition and aggregation mechanisms. The memo provides a basis for additional documents that implement the framework to define detailed compositions and aggregations of metrics which are useful in practice.

Stephan Filename : draft-ietf-ippm-spatial-composition-09.txt Pages : 27 Date : 2009-06-23 This memo utilizes IPPM metrics that are applicable to both complete paths and sub-paths, and defines relationships to compose a complete path metric from the sub-path metrics with some accuracy w.r.t. the actual metrics. This is called Spatial Composition in RFC 2330. The memo refers to the Framework for Metric Composition, and provides background and motivation for combining metrics to derive others. The descriptions of several composed metrics and statistics follow.

I've had your comments on the to-do list for several months
(after re-discovering them at IETF in March, where we discussed
them face2face).  As mentioned, I think some are best
dealt-with in the framework draft, instead of the draft you reviewed.
 
I have inserted pointers below where you will find
the text that (I believe) addresses your points/questions:
F(section number) = draft-...-framework-compagg-08
S(section number) = draft-...-spatial-composition-09

thanks for both your comments and patience,
Al

2) The whole idea of paths being subdivided into subpaths needs
   further clarification and most probably constaints.
   I will discuss this further in separate emails,
   but let me explain in a few words what I mean :
   A) Subpaths may be joined at a link or at a node;
      there are reasons for both
      (e.g. ITU recommends different operator domains joining at a link,
      while border routers and PWE stitching points join at nodes.
      Note that when the joining is at a node the end-to-end
      packet loss is the sum of the packet losses in the pieces
      and that of the shared node, while when the joining is at a link
      the end-to-end delay is the sum of the delays and that of the link.
      MEF studied some of the effects of this in an ad-hoc group
      called "accurate frame loss".

It's an interesting point. In IPPM,
we are in the Active measurement space,
so we terminate only on hosts.
F(3.10) and F(6.2)

   B) There are frequently multiple paths between the endpoints.
      These multiple paths can all be used in at least 3 cases
      i) rerouting events
      ii) ECMP/LAG
      iii) inverse mux.
      I don't know if these mechanisms have ever been seriously discussed
      in IPPM. Their effect is more general than the spatial composition case,
      but is particularly significant for this case.

Yup, more in S(4.1.8.1) now on this.

 
3) page 5 - the use of spatial composition may also be the reverse.
   If we know the end-to-end parameter, and that of all subpaths but one,
   then we can deduce that of the last path.

S(3.1), last paragraph added.

 
4) NIT Section 4 - "The section is organized using the same subsections
   as the individual metrics ...". Yes, that WOULD have been useful,
   but unfortunately sections 5.2 and 5.3 are missing the section
   parallelling 4.1.4 "Statistic", thus e.g. 5.2.6 maps to 4.1.7.

Fixed in the obvious way.

 
5) 5.1.2 (and other places) What is meant by "sufficiently LOW resolution" ?
   At first I thought that this meant course resolution, but then saw delays
   measured in microseconds. Does this actually mean "fine" resolution ?
   Does the statement mean A) course resolution to be reproducible OR
   B) fine resolution to be accurate ?

fine resolution to convey useful info
(0.0s is not fine enough to convey 10ms).
1,$ s/low res/fine res/g

 
6) NIT 5.2.2 (and other places). I am sure that you thought about this,
   but I find it confusing to use the index i to mean packet number
   and afterwards the same index to mean subpath.
   I would like at least for the formula to say
   MeanDelay[i] = 1/N SUM_j=1^N FiniteDelay[i,j]
   where i = 1 to number_of_subpaths and j = 1 to number_of_packets.
   A convention I frequently use in such cases would have
   the subpath index called "s" and have it run from 1 to "S"
   and the packet index called "p" and have it run from 1 to "P".

ok
m = index for packets sent
n = index for packets received
s = index for involved sub-paths


 
7) NIT 5.2.5 - It would have been clearer to me to say that this composition
   means that the mean of the sum equals the sum of the means.
   However, I admit to not understanding the caveat of the continous distributions.
   When the paths contain a small number of nodes the distributions will not
   be continuous at least at the bottom, since there will be a sharply defined
   minimum delay (this sharpness disappears with a large number of nodes
   since the sum of a large number of random variables starts looking Gaussian).
   In any case, it is not obvious to me that discontinuous distributions
   do not add correctly. Can you explain ?

briefly, in S(5.2.6), bimodal is a problem for the mean.

 
8) 5.2.8 Another specific case would be when there is significant delay
   in a link connecting the subpaths

As in F(3.10) and F(6.2), a link with significant delay
would constitute another sub-path to measure.
More in S(5.2.9) now to identify this source of error.

   For 5.3.8 another case would be when the delay depends on packet size
   and this packet size changes when going from subpath to subpath
   as a result of encapsulation changes.

Interesting point.
More in S(4.3.9) now to identify this common source of error.
However, metric definitions focus on the IP packet,
which can change size under fewer circumstances.

I've also added a short discussion of Fragmentation
(considered harmful to composition functions based on
non-fragmented packet measurements...).
