               Geneve encapsulation for In-situ OAM Data
                  draft-brockners-ippm-ioam-geneve-01

Abstract

   In-situ Operations, Administration, and Maintenance (IOAM) records
   operational and telemetry information in the packet while the packet
   traverses a path between two points in the network.  This document
   outlines how IOAM data fields are encapsulated in Geneve.

1.  Introduction

   In-situ OAM (IOAM) records OAM information within the packet while
   the packet traverses a particular network domain.  The term "in-situ"
   refers to the fact that the IOAM data fields are added to the data
   packets rather than is being sent within packets specifically
   dedicated to OAM.  This document defines how IOAM data fields are
   transported as part of the Geneve [I-D.ietf-nvo3-geneve]
   encapsulation.  The IOAM data fields are defined in
