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. 2.
