               Geneve encapsulation for In-situ OAM Data
                  draft-brockners-ippm-ioam-geneve-04

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
   proposes a new Geneve tunnel option and outlines how IOAM data fields
   are carried in the option data field.

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 proposes a new Geneve tunnel option
   and defines how IOAM data fields are transported as part of the
   tunnel option in the Geneve [I-D.ietf-nvo3-geneve] encapsulation.
