        Performance Measurement in Segment Routing Networks with 
                            MPLS Data Plane
                 draft-gandhi-spring-sr-mpls-pm-00.txt

Abstract

   RFC 6374 specifies protocol mechanisms to enable the 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 reviews how these
   mechanisms can be used for Performance Measurements in Segment
   Routing with MPLS data plane (SR-MPLS) networks.
