In-band (or In-situ) Operations, Administration, and Maintenance (IOAM) provides a mechanism to communicate OAM messages over user packets as they travel through a network configured to support that feature. The mechanisms described herein enhance IOAM functionality by defining a superframe structure that consists of one or more follow-on packets that share the same customer packet headers. The superframe structure provides several benefits, including: (1) supporting more flexible and larger messages across one or more IOAM packets; (2) creating lightweight IOAM packets to avoid potential issues due to packet size; and (3) allowing more IOAM message types (through a capability field) to be supported.
