                      draft-ietf-bier-pmmm-oam-08

Abstract

   This document describes the applicability of a hybrid performance
   measurement method for packet loss and packet delay measurements of a
   multicast service through a Bit Index Explicit Replication domain.

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.
