Data Fields for In-situ OAM
draft-brockners-inband-oam-data-05
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
discusses the data fields and associated data types for in-situ OAM.
In-situ OAM data fields can be embedded into a variety of transports
such as NSH, Segment Routing, Geneve, native IPv6 (via extension
header), or IPv4. In-situ OAM can be used to complement OAM
mechanisms based on e.g. ICMP or other types of probe packets.
