             draft-zhou-ippm-enhanced-alternate-marking-01

Abstract

   This document proposes several ways to encapsulate the alternate
   marking field with enough space.  More information can be considered
   within the alternate marking field to facilitate the efficiency and
   ease the deployment.

1.  Introduction

   The Alternate Marking [RFC8321] technique is an hybrid performance
   measurement method, per [RFC7799] classification of measurement
   methods.  It can be used to measure packet loss, latency, and jitter
   on live traffic.  Because this method is based on marking consecutive
   batches of packets.

   For the basic Alternate Marking method, bits are needed to record the
   mark.  However, in some protocols, no additional bit can be used,
   which blocks the wide deployment of the alternate marking technique.
   And the basic Alternate Marking method is limited with the
   scalability for further extension.

   This document proposes several ways to encapsulate the alternate
   marking field with enough space.  More information can be considered
   within the alternate marking field to facilitate the efficiency and
   ease the deployment.  Specifically, the flow identifier is applied as
   an enhancement for the basic Alternate Marking when determining
   packet loss and packet delay measurement.  The flow identifier helps
