Patent ID: 7986623

Claim:
a method for rejecting a request to alter a connection, comprising: establishing a first connection with a first node of a network at a third node of the network; establishing a second connection with a second node of the network at the third node of the network, the second connection passing through the first node and having an associated first end-to-end state; transmitting from the third node, for relay by the first node to the second node, a first request to alter the second connection with the second node so that the second connection will have an associated second end-to-end state, wherein the first request to alter the second connection comprises a first request selected from the group consisting of a request to delete the second connection and a request to perform an administrative modification to the second connection; at the third node, receiving a rejection message from the first node indicating that the first request to alter the second connection failed; and transmitting from the third node a second request to alter the second connection with the second node to revert the second connection back to the associated first end-to-end state in the case that one of the nodes made changes to the end-to-end state in anticipation of the failed request to alter the second connection.
