In Situ OAM Profiles
draft-mizrahi-ippm-ioam-profile-01
Abstract
In Situ Operations, Administration and Maintenance (IOAM) is used for
monitoring network performance and for detecting traffic bottlenecks
and anomalies. This is achieved by incorporating IOAM data into in-
flight data packets. This document introduces the concept of use
case-driven IOAM profiles. An IOAM profile defines a use case or a
set of use cases for IOAM, and an associated set of rules that
restrict the scope and features of the IOAM specification, thereby
limiting it to a subset of the full functionality. The motivation
for defining profiles is to limit the scope of IOAM features,
allowing simpler implementation, verification, and interoperability
testing in the context of specific use cases that do not require the
full functionality of IOAM.
