Abstract
A method and apparatus of releasing resources allocated to terminated sessions at a secondary data processing node. A first node transmits one or more switch messages to a second node requesting the second node to redistribute sessions on a first route between the nodes among one or more alternate routes. Each switch message identifies the sessions to be switched and an alternate route to which the sessions are to be switched. The last switch message transmitted by the first node is indicated to be the last message in some appropriate way and includes a count of the total number of sessions that have been requested to be switched. The second node accumulates a count of the total number of sessions on the first route for which it has received a switch request. The second node compares its accumulated count with the total count derived from the last switch message and releases the resources allocated to all remaining sessions on the first route in the event the counts are equal.
