      Performance Measurement in Segment Routing Networks with 
                        IPv6 Data Plane (SRv6)
                   draft-ali-spring-srv6-pm-00.txt 

Abstract

   RFC 6374 specifies protocol mechanisms to enable efficient and
   accurate measurement of packet loss, one-way and two-way delay, as
   well as related metrics such as delay variation and channel
   throughput in MPLS networks.  This document describes how these
   mechanisms can be used for performance measurement in Segment Routing
   with IPv6 data plane (SRv6) networks.
