Real-time admission control algorithms with delay and loss guarantees in ATM networks

A multimedia ATM network is shared by media streams with different performance requirements. For media streams such as file transfers, the preservation of bursts and the provision of guarantees for loss probability at the burst level is of primary importance, while, for media streams such as voice, loss guarantees at the cell level are sufficient. Continuous media have stringent delay jitter requirements. Finally, some applications require loss-free transmission. In this paper the first complete traffic management scheme for multimedia ATM networks is introduced supporting a wide variety of quality of service requirements. The operation of the traffic management scheme is completely specified, and real-time admission control algorithms are provided
