                      Data Fields for In-situ OAM
                      draft-ietf-ippm-ioam-data-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
   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.
