Hi All,
This draft comprehensively details procedures for leveraging the STAMP to
measure performance in Segment Routing networks (SR-MPLS/SRv6). Especially, the
new extension of STAMP to support new modes (one-way, loopback, and
timestamp-and-forward) significantly enhances scalability and practicality for
operational deployments. Below are some suggestions for further discussion.
It will be better to add descriptions of Business Edition (BE) scenarios,
covering both the SR-MPLS and SRv6 planes, to ensure the document encompasses
all SR situations.
The document hints at the capability negotiation mechanisms for the newly
defined MNA.TSF and End.TSF in sections 7.1.2 and 7.2.2, but without specifics.
Detailed elaboration is suggested.
It39s advised to outline clock synchronization requirements separately for
one-way and two-way measurements, as well as for packet-loss measurement. This
would better inform real network deployments.
Best Regards,
Liyan

Abstract:
Segment Routing (SR) leverages the source routing paradigm and
applies to both Multiprotocol Label Switching (SR-MPLS) and IPv6
(SRv6) data planes. This document describes procedures for
Performance Measurement in SR networks using the Simple Two-Way
Active Measurement Protocol (STAMP) defined in RFC 8762, along with
its optional extensions defined in RFC 8972 and further augmented in
RFC 9503. The described procedure is used for links and SR paths
(including SR Policies and SR IGP Flexible Algorithm paths), as well
as Layer-3 and Layer-2 services in SR networks, and is applicable to
both SR-MPLS and SRv6 data planes.
