   Segment Routing (SR) leverages the source routing paradigm.  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 in MPLS networks using probe
   messages.  This document utilizes these mechanisms for Performance
   Delay and Loss Measurements in Segment Routing networks with MPLS
   data plane (SR-MPLS), for both SR-MPLS Links and end-to-end Paths
   including SR-MPLS Policies.  In addition, this document defines
   Return Path TLV for two-way performance measurement and Block Number
   TLV for loss measurement.
