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).
   [I-D.ietf-ippm-alt-mark] describes 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 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.
