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.
