Performance Measurement Using TWAMP Light and STAMP for Segment Routing
Networks
draft-gandhi-spring-twamp-srpm-07
Abstract
Segment Routing (SR) leverages the source routing paradigm. SR is
applicable to both Multiprotocol Label Switching (SR-MPLS) and IPv6
(SRv6) data planes. This document specifies procedure for sending
and processing probe query and response messages for Performance
Measurement (PM) in Segment Routing networks. The procedure uses the
messages defined in RFC 5357 (Two-Way Active Measurement Protocol
(TWAMP) Light) and Simple Two-Way Active Measurement Protocol (STAMP)
for Delay Measurement, and uses the messages defined in this document
for Loss Measurement. The procedure specified is applicable to SR-
MPLS and SRv6 data planes and is used for both Links and end-to-end
SR Policies.
