CoA Requests
CoA requests, as described in RFC 5176, are used in a pushed model to allow for session identification, host reauthentication, and session termination. The model comprises one request (CoA-Request) and two possible response codes:
CoA acknowledgment (ACK) [CoA-ACK]
CoA non-acknowledgment (NAK) [CoA-NAK]
