Abstract

The design principles of resource control algorithms based on asynchronous time-sharing (ATS) are addressed, together with their interaction and cooperation in a wide area network environment, and a framework for evaluating the overall performance of the system is presented. The basic concepts of the ATS framework are presented, along with an overview of an architecture for joint scheduling and admission control. Scheduling mediates the low-level competition for service between cells of different classes; admission control regulates the acceptance or blocking of incoming traffic on a call-by-call basis. The performance of the scheduling algorithms is evaluated and the interaction between scheduling and admission control is quantified. A reference model for broadband networks is presented
