Implementation of IOAM for IPv6 in the Linux Kernel

TL;DR

This paper presents the first implementation of IOAM for IPv6 in the Linux kernel, enabling in-packet telemetry collection, with a preliminary evaluation demonstrating its functionality in a controlled setting.

Contribution

It introduces the initial Linux kernel implementation of IOAM for IPv6 and provides an open-source version along with a preliminary performance evaluation.

Findings

Implementation successfully integrates IOAM in Linux kernel for IPv6

Preliminary tests confirm operational functionality

Open-source availability facilitates further research

Abstract

In-situ Operations, Administration, and Maintenance (IOAM) is currently under standardization at the IETF. It allows for collecting telemetry and operational information along a path, within the data packet, as part of an existing (possibly additional) header. This paper discusses the very first implementation of IOAM for the Linux kernel with IPv6 as encapsulation protocol. We also propose a first preliminary evaluation of our implementation under a controlled environment. Our IOAM implementation is available as open source.
