ABSTRACT:
A method of communicating messages across a network is provided. A router receives an RSVP (Resource Reservation Protocol) PATH message from a sending host that is directed to a receiving host. Upon identifying the protocol of the incoming PATH message as RSVP, the router accesses a proxy look-up table to identify a proxy host acting on behalf of the receiving host. The router then adds a proxy header to the PATH message and redirects the PATH message to the proxy host by sending the message to a predetermined port. The proxy host receives the PATH message and, in response, sends a resource reservation request (RESV) message onto the network with a proxy header and directed to the predetermined port. The router receives the RESV message, strips off the proxy header, and forwards the RESV message to the sending host as if the message had originated from the receiving host. A proxy host can also send PATH messages on behalf of the sending host. In that case, the proxy host adds a proxy header to the PATH message and directs the PATH message to the predetermined port. The router receives the PATH message, strips off the proxy header, and sends the PATH message to the receiving host as if the PATH message had originated form the sending host. The router also receives RESV messages from the receiving host or its proxy and redirects them to the proxy for the sending host.
