Abstract

This paper presents a high-speed CAC scheme, called PERB CAC (CAC based on Prior Estimation for Residual Bandwidth). This scheme estimates the residual bandwidth in advance by generating virtual requests for connection. When an actual new request occurs, PERB CAC can instantaneously judge if the required bandwidth is larger than the estimated residual bandwidth. PERB CAC provides very rapid response time both for statistical and deterministic. bandwidth allocation services, while keeping statistical multiplexing gain for the former service. Numerical results indicate that PERB CAC provides reasonably accurate and conservative values of residual bandwidth. In addition, by using PERB CAC, both services are able to be accommodated into a single VP. VP capacity control is more relaxed than is true with conventional VP-separation management. This is another merit of PERB CAC. Therefore, PERB CAC can achieve high-speed connection set-up while utilizing network resources in a cost-effective manner.
