1. Introduction
[RFC8279] introduces and explains the Bit Index Explicit Replication
(BIER) architecture and how it supports the forwarding of multicast
data packets. [RFC8296] specified that in the case of BIER
encapsulation in an MPLS network, a BIER-MPLS label, the label that
is at the bottom of the label stack, uniquely identifies the
multicast flow. [RFC8321] describes a hybrid performance measurement
method, according to the classification of measurement methods in
[RFC7799]. The method, called Packet Network Performance Monitoring
(PNPM), can be used to measure packet loss, latency, and jitter on
live traffic complies with requirements #5 and #12 listed in
[I-D.ietf-bier-oam-requirements]. Because this method is based on
marking consecutive batches of packets, the method is often referred
to as a marking method. Terms PNPM and "marking method" in this
document are used interchangeably.
This document defines how the marking method can be used on the BIER
layer to measure packet loss and delay metrics of a multicast flow in
an MPLS network.
