Performance Measurement for Geneve
draft-xiao-nvo3-pm-geneve-00
Abstract
This document describes the method to achieve Performance Measurement
(PM) in point-to-point Generic Network Virtualization Encapsulation
(Geneve) tunnels that form an overlay network.

1. Introduction
"Generic Network Virtualization Encapsulation" (Geneve)
[I-D.ietf-nvo3-geneve] provides an encapsulation scheme that allows
building an overlay network by decoupling the address space of the
attached virtual hosts from that of the network.
This document describes the use of Packet Loss and Delay Measurement
for MPLS Networks [RFC6374], as well as Simple Two-way Active
Measurement Protocol [I-D.ietf-ippm-stamp], to enable measuring the
performance of the path between two Geneve tunnel endpoints.
In this document, NVE (Network Virtualization Edge) represents a
Geneve tunnel endpoint, TS (Tenant System) represents a physical or
virtual device attached to a Geneve tunnel endpoint, and VAP (Virtual
Access Point) represents the NVE side of the interface between the
NVE and the TS.
