            IPv6 Application of the Alternate Marking Method
                     draft-fz-6man-ipv6-alt-mark-02

Abstract

   This document describes how the Alternate Marking Method can be used
   as the passive performance measurement tool in an IPv6 domain and
   reports implementation considerations.  It proposes how to define a
   new Extension Header Option to encode alternate marking technique and
   also considers the Segment Routing Header TLV alternative.

1.  Introduction

   [RFC8321] and [I-D.ietf-ippm-multipoint-alt-mark] describe passive
   performance measurement method, which can be used to measure packet
   loss, latency and jitter on live traffic.  Since this method is based
   on marking consecutive batches of packets, the method often referred
   as Alternate Marking Method.

   This document defines how the alternate marking method can be used to
   measure packet loss and delay metrics of IPv6.  Consequently, the
   SRv6 (Segment Routing over IPv6 data plane) application is also
   discussed.  Both Extension Header (EH) Option and Segment Routing
   Header (SRH) TLV are considered here.

   The format of the IPv6 addresses is defined in [RFC4291].  [RFC8200]
   introduces the IPv6 Header Format, including the Extension Headers in
   the base IPv6 Header and the availability of a 20-bit flow label.  In
   this respect, [I-D.fioccola-v6ops-ipv6-alt-mark] reported a summary
   on the possible implementation options for the application of the
   alternate marking method in an IPv6 domain.  This document, starting
   from the outcome of [I-D.fioccola-v6ops-ipv6-alt-mark], introduces a
   new Option/TLV that can be encoded as EH Option or as SRH TLV.
