Interworking connectionless service with ATM network for multimedia communication

Abstract

Effective resource allocation for connectionless services through an ATM network is an important problem to be solved in interconnecting nation wide multimedia communication networks. Instead of separated bandwidth renegotiation for variable bit rate traffic of each LAN/MAN, using the statistical multiplexing of several LANs traffic can increase the network resource utilization and satisfy the quality of service requirements for multimedia communication. For multiplexed multimedia LAN traffic, we develop a dynamic resource allocation scheme which is mainly controlled by a connectionless server (CLS) that supports connectionless service function (CLSF) in an ATM network. The simulation results show that our scheme improves performance and is robust to user traffic behaviors.
