Abstract

In future B-ISDN and PCN environments, an increasing number of network control services, such as dynamic multiparty conferences, mobile call handoff, etc., will require realtime connection rerouting services not currently supported by the B-ISDN signaling network architecture based on the SS7 CCS network and its transaction protocols (TCAP). To support these services, we propose a novel signaling network architecture employing the following new signaling transport protocols in the signaling ATM adaptation layer: (1) associated-CCS employing source-routing unicast and multicast to provide fast distributed signaling transport for realtime distributed transactions, and (2) inband signaling required for synchronization data transport, and the following new transaction protocols in the TCAP layer: (1) robust fast reservation of communication resources, (2) packet-ordering synchronization to minimize traffic disruptions.
