                   Enhanced Alternate Marking Method
             draft-zhou-ippm-enhanced-alternate-marking-04

Abstract

   This document defines data fields for the alternate marking with
   enough space.  The main idea is that more information can be
   considered within the alternate marking field to facilitate the
   efficiency and ease the deployment.  The definition aims to be
   general, even if for some protocols there can be dedicated solutions.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

1.  Introduction

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

   For the basic Alternate Marking method, bits are needed to record the
   mark.  For some protocols (e.g.  MPLS, BIER, SFC, NVO3) dedicated
   solutions have been presented ([I-D.ietf-mpls-rfc6374-sfl],
   [I-D.ietf-bier-pmmm-oam], [I-D.mirsky-sfc-pmamm],
   [I-D.fmm-nvo3-pm-alt-mark]), but there are ongoing discussions on
   this matter.

   However, in most of the protocols, no additional bit can be used or
   proposed, and that blocks the wide deployment of the alternate

   marking technique.  In addition, the basic Alternate Marking method
   is limited with the scalability issue for further extension, i.e,
   more measurements in addition to existing use.
