Abstract
In one embodiment, in-band operations data (e.g., In-situ Operations, Administration, Maintenance and/or other operations data) is added to Seamless Bidirectional Forwarding (S-BFD) packets. In one embodiment, a S-BFD packet received by a node includes a BFD discriminator and operations data. Reactive processing is identified based on the BFD discriminator. The S-BFD packet and the operations data (e.g., in an operations data field in a header of the received S-BFD packet, in an IOAM Type-Length-Value (TLV), etc.) is processed according to the identified reactive function. Examples of these reactive actions include, but are not limited to, determining a result based on processing of said particular operations data by the local node or a remote analytics server, and sending a response packet including unprocessed and/or a result of the processed operations data (e.g., performance, loss, jitter, an indication of compliance with a service level agreement, and/or another data measurement or result).
