                Performance Measurement Using UDP Path 
                     for Segment Routing Networks
               draft-gandhi-spring-rfc6374-srpm-udp-02

Abstract

   Segment Routing (SR) leverages the source routing paradigm.  Segment
   Routing (SR) is applicable to both Multiprotocol Label Switching
   (SR-MPLS) and IPv6 (SRv6) data planes.  This document specifies
   procedures for using UDP path for sending and processing probe query
   and response messages for Performance Measurement (PM).  The
   procedure uses the mechanisms defined in RFC 6374 for Performance
   Delay and Loss Measurement.  The procedure specified is applicable to
   SR-MPLS and SRv6 data planes for both links and end-to-end
   measurement for SR Policies.
