Two-dimensional shared memory multicast ATM switching architecture

Currently, the advances in the communication field are tending towards the Broadband integrated Services Digital Network (BISDN) based on the Asynchro nous Transfer Mode (ATM). Although numerous studies have been carried out i n point-to-point switching systems, the point-to-multipoint switching syste m has gradually gained significance in recent years. To meet the requiremen t of the multicast service, we proposed a high-performance multicast switch ing system. There are easy ways to setup and release a multicast call. Only one copy of the address mapping information should be maintained in the sy stem. The multicast cell overflow condition is trivially solved by our prop osed switching architecture. We provide an overlay scheme to reduce delay n eeded in the multicast cell copying process. Finally, we afford a simulatio n result to evaluate the performance of the proposed multicast switching sy stem. (C) 1999 Elsevier Science B.V. All rights reserved.
