The IESG has received a request from the IP Performance Metrics WG (ippm)
to consider the following document:
- 'IPPM standard advancement testing'
  <draft-ietf-ippm-metrictest-05.txt> as a BCP

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2011-12-15. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

This document includes a normative reference to RFC 2330, which is an
Informational RFC, however, RFC 2330 has been used as a normative
reference in several other IPPM working group documents, though some
predate the requirement to split normative and informative references.  One
example of an existing normative reference to RFC 2330 is found in RFC
6049.  The IESG is particularly interested in determining whether the
community considers RFC 2330 sufficiently mature to serve as a normative
reference for standards track and BCP publications.

I should explain to the working group what the 2nd IETF LC for this
document is about.

During the IESG evaluation on the document, it was determined that
this really needed to be a BCP since it's about process.

Also, it was pointed out that the normative reference to RFC 2330
needs to be pointed out in the IETF LC since 2330 is Informational.
Once this has been done, it can be added to the down-ref registry,
if the IETF doesn't express any issue with that (and it shouldn't
since 2330 has been cited this way before).

Thanks for bearing with the 2nd IETF LC on this!

Y.1731 has several functions that may overlap OWAMP or TWAMP functions.
As does 802.3 Clause 57 (EFM OAM).

However, Y.1731 divides up the functionality into separate packets,
one type for packet loss, one type for delay measurement, etc.
Each of these functions triggers calculation at the OAM endpoints,
rather than sending the raw data to a controller for processing.

Also, Y.1731 is typically often used continuously, or at least periodically=
,
rather than setting up a test session as in xWAMP.

Finally, Y.1731 does not define a security mechanism.
although it could be used in association with one (e.g., MACsec).

Y.1731 is widely adopted standard and many vendors support it. Is TWAMP
also widely adopted ?

Y.1731 can be configured per vlan. Does TWAMP needs to be per vlan ?

Is it possible to implement TWAMP security mechanism in hardware ? If it
is not, how efficient its implementation in software ?

Yes, "About 12,600 results" on Google...


>Y.1731 can be configured per vlan. Does TWAMP needs to be per vlan ?

you can put the test stream in a VLAN, If that's the question.

with the mixed-mode feature, efficiency is less of an issue...

IPPM Group,

The chairs are currently discussing if we have to have a face-2-face
meeting at the next IETF in Paris.  If you have topics that need
discussion, please drop us a note before January 25.

Season's greetings,

Henk
