Re: [ippm] New Version for draft-wang-ippm-stamp-hbh-extensions-01

Hi Yali,

I think this is a useful solution. Hop-by-hop network measurement is very necessary in many scenarios. 
I have a few questions.
1. Why is it combined with OAM packets and how to deal with devices that do not support OAM?
2. Latency, jitter, and packet loss are mentioned in the document, but link bandwidth utilization is also an important indicator. Can it also be implemented in this solution?

Thanks and Best Regards,
Hongwei.

Hello WG,

Draft about extensions to STAMP enable hop-by-hop OAM data measurement and collection has been updated, which was presented in IETF108. Questions and comments are welcome.

Because the performance of intermediate nodes and links that STAMP test packets traverse are invisible, to solve this problem, this draft extents optional TLVs to STAMP and inserts IOAM Trace option data in the test packets or dispatches test packets to the OAM process at OAM Endpoint.

In this case, the STAMP instance does not need to be configured at every intermediate node to measure the performance of intermediate nodes, which decreases the complexity of OAM in large-scale networks.

What do you think?

Best regards,
Yali

Abstract:
   This document defines optional TLVs which are carried in Simple Two-
   way Active Measurement Protocol (STAMP) test packets to enhance the
   STAMP base functions.  Such extensions to STAMP enable OAM data
   measurement and collection at every node and link along a STAMP test
   packet's delivery path.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
