CONNECTION ADMISSION CONTROL SYSTEM (CAC) FOR ATM NETWORKS

摘要

A method of carrying out connection admission control in an asynchronous network, comprises determining the virtual bandwidth in the set-up phase using a closed-form virtual bandwidth formula generalized from the exponential bounds for the queue length of incoming cells at a queuing point using a Martingale function, and permitting a connection to be established or maintained when the following condition is met: Σ virtual bandwidthj x number of connections of type j≤C( available bandwidth). The invention is useful for effecting connection admission control in ATM or like asynchronous data networks.
