1. Introduction
[I-D.ietf-bier-architecture] introduces and explains Bit Index
Explicit Replication (BIER) architecture and how it supports
forwarding of multicast data packets.
[I-D.ietf-bier-mpls-encapsulation] specified that in case of BIER
encapsulation in MPLS network a BIER-MPLS label, label that is at the
bottom of the label stack, uniquely identifies the multicast flow.
[I-D.tempia-ippm-p3m] describes passive performance measurement
method , Packet Network Performance Monitoring (PNPM), which can be
used to measure packet loss, latency and jitter on live traffic.
Because this method is based on marking consecutive batches of
packets the method often referred as Marking Method (MM).
This document defines how marking method can be used on BIER layer to
measure packet loss and delay metrics of a multicast flow in MPLS
network.
