Re: [ippm] FW: New Version Notification for draft-wang-ippm-stamp-hbh-extensions-04.txt

Hi Zhenqiang,
Thank you for the feedback.
For the STAMP HbH active measurements, I think that the best way is to use the STAMP HbH TLVs, as proposed in the draft, without relying on IOAM. Indeed, if you have to extend STAMP to allow HbH active measurements, it is more straightforward to define new TLVs directly in STAMP, as per RFC 8972.
But, in case you are using IOAM at the network layer (e.g. IPv6) for hybrid measurements and you only want to collect the information, you raised a good point. This draft proposes to include the IOAM tracing TLV in STAMP to carry back the forward IOAM data to the sender. Otherwise, as you highlighted, you can use IOM-DEX to export the information to the NMS. I think that both options can be useful and the choice also depends whether there is an external NMS and whether you want to send all the collected data to the NMS.
I will add this consideration in the next revision of the draft.

Regards,

Giuseppe

Hello Giuseppe and all,

Why not apply iOAM on STAMP test packets? In this way we can get all the information you want. The performance information per hop doesn't need to be carried back to the sender and then be reported to a NMS. If necessary, NMS can collect the performance information per hop directly by iOAM in postcard mode.

Hi All,
Please note that we have just updated the draft on STAMP extensions for Hop-by-Hop data collection. These extensions to STAMP enable OAM data measurement at every node and link along a STAMP test path.

Your comments and reviews are welcomed.

Regards,

Giuseppe

A new version of I-D, draft-wang-ippm-stamp-hbh-extensions-04.txt
has been successfully submitted by Giuseppe Fioccola and posted to the IETF repository.

Name: draft-wang-ippm-stamp-hbh-extensions
Revision: 04
Title: Simple Two-way Active Measurement Protocol Extensions for Hop-by-Hop OAM Data Collection
Document date: 2023-07-07
Group: Individual Submission
Pages: 18

Abstract:
   This document defines optional TLVs which are carried in Simple Two-
   way Active Measurement Protocol (STAMP) test packets to enhance the
   STAMP based functions.  Such extensions to STAMP enable OAM data
   measurement and collection at every node and link along a STAMP test
   packet's delivery path without maintaining a state for each
   configured STAMP-Test session at every devices.
