摘要
In an ATM network, the physical resources are shared by many connection and the bandwidth is allocated virtually to each connection. The connection admission control (CAC) algorithm uses traffic descriptors, desired quality of service (QOS) parameters etc., to compute a required bandwidth for a requested connection by which it makes a decision to admit or reject the connection. For admission control for a requested VBR connection, two required bandwidths are calculated in two different ways, both of which take into consideration impacts of CBR traffic which is being serviced. The admission decision is based on the lesser of the two bandwidths.
