  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.
