            IPv6 Application of the Alternate Marking Method
                     draft-fz-6man-ipv6-alt-mark-00

Abstract

   This document describes how the alternate marking method in [RFC8321]
   and [I-D.ietf-ippm-multipoint-alt-mark] can be used as the passive
   performance measurement method in an IPv6 domain and reports
   implementation considerations.  It proposes how to define a new
   encapsulation header to encode alternate marking technique.

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 and SRv6.

   The IPv6 Header Format defined in [RFC8200] introduces the format of
   the IPv6 addresses, the Extension Headers in the base IPv6 Header and
   the availability of a 20-bit flow label, that can be considered for
   the application of the Alternate Marking methodology.  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.

   [I-D.zhou-ippm-enhanced-alternate-marking] defines the data field for
   the alternate marking in order to generalize its application.  More
