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, per RFC7799's classification of measurement methods
   [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.

   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.
