Patent ID: 7702816

Claim:
A method for facilitating application synchronization with a reservation protocol at a sender node without application receiver participation in a computer network, the method comprising: sending a path request message from the sender node to a reservation receiver; receiving the path request message at the reservation receiver; in response, returning a reservation request message from the reservation receiver to the sender node, the reservation request message including a request for fast reservation failure notification to be sent to the sender node if an error occurs in response to the reservation request message, fast reservation failure notification being notification that bypasses per-hop processing at intervening nodes while in transit; detecting an error in response to the reservation request message at an intermediate node between the sender node and reservation receiver; in response, sending fast reservation failure notification from the intermediate node to the sender node; and synchronizing the application with the reservation protocol without application receiver participation based on receipt of either the fast failure notification or a successful reservation request message at the sender node.
