In-situ OAM raw data export with IPFIX
draft-spiegel-ippm-ioam-rawexport-04
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.
