In-situ OAM Direct Exporting
draft-ioamteam-ippm-ioam-direct-export-00
Abstract
In-situ Operations, Administration, and Maintenance (IOAM) is used
for recording and collecting operational and telemetry information.
Specifically, IOAM allows telemetry data to be pushed into data
packets while they traverse the network. This document introduces a
new IOAM option type called the Direct Export (DEX) option, which is
used as a trigger for IOAM data to be directly exported to a
collector without being pushed into in-flight data packets.

1. Introduction
IOAM [I-D.ietf-ippm-ioam-data] is used for monitoring traffic in the
network, and for incorporating IOAM data fields into in-flight data
packets.
IOAM makes use of four possible IOAM options, defined in
[I-D.ietf-ippm-ioam-data]: Pre-allocated Trace Option, Incremental
Trace Option, Proof of Transit (POT) Option, and Edge-to-Edge Option.
This document defines a new IOAM option type (also known as an IOAM
type) called the Direct Export (DEX) option. This option is used as
a trigger for IOAM nodes to export IOAM data to a collector.
