               Residence Time Measurement in MPLS network
                   draft-ietf-mpls-residence-time-11

Abstract

   This document specifies G-ACh based Residence Time Measurement and
   how it can be used by time synchronization protocols being
   transported over MPLS domain.

   Residence time is the variable part of propagation delay of timing
   and synchronization messages and knowing what this delay is for each
   message allows for a more accurate determination of the delay to be
   taken into account in applying the value included in a PTP event
   message.
