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 how In-situ Operations, Administration, and Maintenance
   (IOAM) information can be exported in raw, i.e. uninterpreted, format
   from network devices to systems, such as monitoring or analytics
   systems using IPFIX.
