Abstract

A method for resynchronizing message traffic in a communication network following network component failure. The failing component, upon restart, establishes a second path for communicating with the still active communication network components. The alternate path is used to query status from the operational components and to inform the failed component of synchronization data. Control information for a primary virtual route is updated based upon the status query. This updated information is used to resynchronize message activity and allow resumption of message traffic without reinitializing the network.
