Hi Rakesh,

after brief reading, I think the basic motivation of the draft seems alright. Thoughts:

  *   The draft should add a BER metric definition, as is available for other IPPM metrics.
  *   The draft should provide some more discussion on parametrization. If all L1/L2/L3 headers and non-bit-pattern fields are larger than the measurement bit-pattern, it is more likely that a bit-error hits one of these non-measurement fields.
  *   I also missed a discussion, whether and if yes how the "Bit Pattern in Padding Data" bit pattern is protected against bit errors or how these are detected, if they occurred.


Regards,

Ruediger

Hi IPPM WG,

We have introduced a new draft on using STAMP for Bit Error Detection.

We would greatly appreciate your thoughts and any suggestions you may have.
Thanks,
Rakesh (for authors)

A new version of Internet-Draft draft-gandhi-ippm-stamp-ber-00.txt has been
successfully submitted by Rakesh Gandhi and posted to the

Name:     draft-gandhi-ippm-stamp-ber
Revision: 00
Title:    Simple Two-Way Active Measurement Protocol (STAMP) Extensions for Bit Error Detection and Bit Error Rate Measurement
Date:     2025-04-16
Group:    Individual Submission
Pages:    10
URL:      https://www.ietf.org/archive/id/draft-gandhi-ippm-stamp-ber-00.txt
Status:   https://datatracker.ietf.org/doc/draft-gandhi-ippm-stamp-ber/
HTMLized: https://datatracker.ietf.org/doc/html/draft-gandhi-ippm-stamp-ber


Abstract:

   The Simple Two-Way Active Measurement Protocol (STAMP), as defined in
   RFC 8762, along with its optional extensions specified in RFC 8972,
   can be utilized for active measurement.  This document further
   augments the STAMP extensions specified in RFC 8972 to enable the
   detection of bit errors and the measurement of the bit error rate
   (BER) within the "Extra Padding Data" of STAMP packets.
