Tel:1-409-845-5469, Fax:1-409-847-8578 In this paper, we propose a system of admission control and packet forwarding scheme to improve scalability of networks while guaranteeing end-to-end delay deadlines for real-time applications. We achieve this by using an o-line delay computation and verication step which allows to reduce the overhead at admission control while keeping admission probability and resources utilization high. Indeed, our evaluation data show our system's admission probabilities are very close to those of signicantly more expensive approaches. At the same time, admission control overhead during ow establishment is very low. Our results therefore support the claim from the DS architecture literature that scalablity can be achieved through ow aggregation without sacricing resource utilization and with signicant reduction in run time, |
