A YANG Data Model for In-Situ OAM
draft-zhou-ippm-ioam-yang-07
Abstract
In-situ Operations, Administration, and Maintenance (IOAM) records
operational and telemetry information in user packets while the
packets traverse a path between two points in the network. This
document defines a YANG module for the IOAM function.

1. Introduction
In-situ Operations, Administration, and Maintenance (IOAM)
[I-D.ietf-ippm-ioam-data] records OAM information within user packets
while the packets traverse a network. The data types and data
formats for IOAM data records have been defined in
[I-D.ietf-ippm-ioam-data]. The IOAM data can be embedded in many
protocol encapsulations such as Network Services Header (NSH) and
IPv6.
This document defines a data model for IOAM capabilities using the
YANG data modeling language [RFC7950]. This YANG model supports all
the five IOAM options, which are Incremental Tracing Option, Pre-
allocated Tracing Option, Direct Export
Option[I-D.ietf-ippm-ioam-direct-export], Proof of Transit Option,
and Edge-to-Edge Option.
