IPv6 Application of the Alternate Marking Method
draft-ietf-6man-ipv6-alt-mark-01
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
both Hop-by-Hop Options Header and Destination Options Header are
considered.

1. Introduction
[RFC8321] and [I-D.ietf-ippm-multipoint-alt-mark] describe a 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 is often
referred as Alternate Marking Method.
The Alternate Marking Method has become mature to be implemented and
encoded in the IPv6 protocol and this document defines how it can be
