1.  Introduction

   [RFC7665] introduced architecture of a Service Function Chain (SFC)
   in the network and defined its components as classifier, Service
   Function Forwarder (SFF), and Service Function (SF).  [RFC8321]
   describes the passive performance measurement method, 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 Alternate Marking Method
   (AMM).

   This document defines how the alternate marking method can be used to
   measure packet loss and delay metrics of a service flow over e2e or
   any segment of the SFC.
