       IPv6 Performance Measurement with Alternate Marking Method
                 draft-fioccola-v6ops-ipv6-alt-mark-01

Abstract

   This document describes how the alternate marking method in [RFC8321]
   can be used as the passive performance measurement method in an IPv6
   domain, and will discuss the strengths and the weaknesses of the
   implementation options available to network operations.  It proposes
   how to extend [RFC7837] to apply alternate marking technique.

1.  Introduction

   This document reports a summary on the possible implementation
   options for the application of the alternate marking method in an
   IPv6 domain.

   [RFC8321] describes passive performance measurement method, which can
   be used to measure packet loss, latency and jitter on live traffic.
   Because 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 tunneled packets or
   SRv6 policies.
