High-speed connection admission control in ATM networks by generating virtual requests for connection

摘要

This paper proposes a high-speed connection admission control scheme, named PERB CAC (CAC based on prior estimation for residual bandwidth). This scheme estimates the residual bandwidth in advance by generating a series of virtual requests for connection. When an actual connection request occurs, PERB CAC can instantaneously judge if the required bandwidth is larger than the estimated residual bandwidth, so the connection set-up time can be greatly reduced. Therefore, PERB CAC can realize high-speed connection set-up.
