                       draft-mirsky-sfc-pmamm-08

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.
