Abstract
The authors present a performance evaluation of a simple yet effective technique for congestion avoidance in broadband integrated services digital networks (B-ISDNs). With this method, an incoming call is accepted only if its bandwidth requirement is not more than a predefined percentage of unused bandwidth at that moment. If this condition is not satisfied by an incoming call, it is blocked and cleared. This technique was simulated for a network that supports three services. The bandwidth requirements (in terms of cells per call) of these services are assumed to be geometrically distributed. Simulation results are presented in terms of call-blocking probabilities for several different cases.Keywords
