ABSTRACT:
A connection admission control system for the link of an ATM switch generally includes a system for accepting a proposed call if the tangent effective bandwidth, a conservative approximation for the bandwidth, of the proposed call when added to the sum of the tangent effective bandwidths of all other calls being handled by that link are less than the capacity of the link is less than the capacity of the link. The proposed call may also be accepted if the zero-loss effective bandwidth for the proposed call when added to the sum of the zero-loss effective bandwidths of all other calls being handled by that link is less than the capacity of the link. The tangent effective bandwidths and zero-loss effective bandwidths are calculated off of the switch by a processor and stored in a table at the switch. When a call request is received it is placed into a connection class, and the tangent effective bandwidth and zero-loss effective bandwidth relating to that connection class is found in the table.
