Thanks Mach for the review comments. We will add following text in the next revision of the documents.

1.  Loss Measurement
 
  The path segment identifier [I-D.spring-mpls-path-segment]
   [I-D.pce-sr-path-segment] of the SR Policy is required for accounting
   received traffic on the egress node for loss measurement.
 
2. Two-way End-to-end Measurement of SR Policy
 
   The path segment identifier [I-D.spring-mpls-path-segment]
   [I-D.pce-sr-path-segment] of the forward SR Policy can be used to
   find the reverse SR Policy to send the probe response message.

Thanks,
Rakesh

    Hi Authors,
     
    The draft-li-pce-sr-path-segment and draft-cheng-spring-mpls-path-segment define the notion of path segment identifier. Could you please consider adding some text in draft-gandhi-spring-udp-pm and draft-gandhi-spring-sr-mpls-pm and how it is applicable to performance measurement in segment routing?
     
    Best regards
    Mach
