Abstract

A real-time admission control scheme is proposed. The real-time admission control scheme of the present invention does not rely on pre-determined threshold limits. Instead, the current resource utilization is evaluated in real time and admission control decisions are based on this real-time evaluation. As soon as a new service request is received, a real-time evaluation of the current resource utilization of each active task (i.e., in all classes, not just the corresponding class) that consumes resources is made. These tasks include the scheduled service requests (e.g., point-to-point calls, conference calls) as well as failure recovery functions. Then, total resource utilization is computed by summing the resource utilization of each active task. Accordingly, a measure of the available system resources is computed.
