                      Data Fields for In-situ OAM
                   draft-brockners-inband-oam-data-03

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, VXLAN-GPE, Geneve, native IPv6 (via
   extension header), or IPv4.  In-situ OAM can be used to complement
   current out-of-band OAM mechanisms based on ICMP or other types of
   probe packets.
