Abstract
A method for establishing and maintaining virtual chains in a distributed computer network during session initiation. In transmitting a session initiation request from an originating network node to a destination network node, a locate chain is established along the path taken with control block resources dedicated to the chain at each intermediate node. By sending a reply with the discard indicator set, the resources at the intermediate nodes become immediately available and only the network node servers maintain knowledge of the pending session initiation and the route selected.
