Data Fields for In Situ Operations, Administration, and Maintenance
RFC 9197, “Data Fields for In Situ Operations, Administration, and Maintenance”, is a Proposed Standard document published in May 2022 by F. Brockners, S. Bhandari, T. Mizrahi. The canonical text is published by the RFC Editor.
Abstract
In situ Operations, Administration, and Maintenance (IOAM) collects operational and telemetry information in the packet while the packet traverses a path between two points in the network. This document discusses the data fields and associated data types for IOAM. IOAM-Data-Fields can be encapsulated into a variety of protocols, such as Network Service Header (NSH), Segment Routing, Generic Network Virtualization Encapsulation (Geneve), or IPv6. IOAM can be used to complement OAM mechanisms based on, e.g., ICMP or other types of probe packets.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
