Performance Measurement Using Simple Two-Way Active Measurement Protocol (STAMP) for Segment Routing over the IPv6 (SRv6) Data Plane

Segment Routing (SR) can be used to steer packets through a network employing source routing. SR can be applied to both MPLS (SR-MPLS) and IPv6 (SRv6) data planes. This document describes the procedures for Performance Measurement for SRv6 using the Simple Two-Way Active Measurement Protocol (STAMP), as defined in RFC 8762, along with its optional extensions defined in RFC 8972 and further augmented in RFC 9503. The described procedures are used for links and SRv6 paths (including Segment Lists of SRv6 Policies, SRv6 IGP best paths, and SRv6 IGP Flexible Algorithm paths), as well as Layer-3 and Layer-2 services over the SRv6 paths.
