While troubleshooting or planning, did you ever wish to get full insight into which paths *all* your packets take in your network, or were you ever asked to prove that your traffic really follows the path you specified by service chaining or that OpenStack configured your vswitch appropriately that traffic really passes through the firewall function? We approach this problem by adding meta-data to *all* live customer traffic. In-band OAM adds forwarding path information and other information/stats to every data packet - as opposed to relying on probe packets, which is the traditional method that tools like ping or traceroute use. This session will introduce In-band OAM (IOAM), explain this new and evolving technology, outline the experimental reference implementation in FD.io/VPP and OpenDaylight using example demos and discuss how IOAM can be used in OPNFV solution stacks, in concert with analytics subsystems (e.g. project OPNFV Bamboo) - as well as how IOAM is standardized in the IETF.
