In-situ OAM Deployment
draft-brockners-opsawg-ioam-deployment-00
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
provides a framework for IOAM deployment and provides best current
practices.
