Abstract
This document describes how the alternate marking method can be used
as the efficient performance measurement method taking advantage of
the actual data flows in a Service Function Chaining (SFC) domain.

1. Introduction
[RFC7665] introduced the 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 hybrid 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.
