     Performance Measurement (PM) with Alternate Marking in Network
                     Virtualization Overlays (NVO3)
                     draft-fmm-nvo3-pm-alt-mark-03

Abstract

   This document describes how the alternate marking method can be used
   for performance measurement method in a Network Virtualization
   Overlays (NVO3) Domain.  The description aims to be general for NVO3
   encapsulations, but is focused to Geneve, recommended by the NVO3
   design team [I-D.ietf-nvo3-encap].

1.  Introduction

   [RFC7365] provides a framework for Data Center (DC) Network
   Virtualization over Layer 3 (NVO3) tunnels.  It is intended to aid in
   standardizing protocols and mechanisms to support large-scale network
   virtualization for data centers.

   [RFC8321] describes a 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 to as the Alternate Marking Method (AMM).

   This document defines how the alternate marking method can be used to
   measure packet loss and delay metrics of an NVO3 Domain.
