1. Introduction
[RFC8279] introduces and explains Bit Index Explicit Replication
(BIER) architecture and how it supports forwarding of multicast data
packets. [RFC8296] specified that in case of BIER encapsulation in
MPLS network a BIER-MPLS label, the label that is at the bottom of
the label stack, uniquely identifies the multicast flow. [RFC8321]
describes hybrid performance measurement method, per [RFC7799]
classification of measurement methods. 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 to 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.
