1. Introduction
"Generic Network Virtualization Encapsulation" (Geneve) [RFC8926]
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 Simple Two-way Active Measurement
Protocol [RFC8762] to enable measuring the performance of the path
between two Geneve tunnel endpoints.
Analogous to [I-D.ietf-nvo3-bfd-geneve], in this document, NVE
(Network Virtualization Edge) represents the Geneve tunnel endpoint,
TS (Tenant System) represents the physical or virtual device attached
to a Geneve tunnel endpoint from the outside, and VAP (Virtual Access
Point) represents the NVE side of the interface between the NVE and
the TS.
