Tight upper bounds for cell loss probabilities and required bandwidth estimation in ATM multiplexers

Estimating the cell loss probability in an ATM multiplexer is a key issue in network management and traffic control tasks such as call admission control and bandwidth allocation. In this paper, we derive a new approximation to estimate the total and individual cell loss probabilities in an ATM multiplexer fed by a superposition of heterogeneous on-off sources. Based on this approximation, a simple algorithm is proposed to estimate accurately the aggregate required bandwidth to guarantee a given cell loss probability. Numerical results and comparisons to alternative approaches are also shown. Supported partly by Hongkong Telecom Institute of Information Technology grant HKTIIT93/94.EG01 2 I. Introduction Due to its ability to integrate different types of traffic with different characteristics and quality of service (QoS) requirements, ATM has been regarded as the desirable transfer mode in the future broadband integrated service digital network (B-ISDN). Generally, QoS can be express..
