ABSTRACT:
Apparatus for executing the connection admission control for PVC and SVC efficiently in an ATM network system which includes a network management equipment and a network equipment. The control function of the network management equipment executes resource allocation to PVC and SVC and notifies the network equipment of resource management information for SVC. For a request of PVC setup, the control function of the network management equipment executes the connection admission control for PVC and notifies the network equipment of the admission result. For a request of SVC setup, the network equipment executes the connection admission control for SVC. Communication overhead is reduced since it is not necessary to inquire the network equipment about connection admission from the network management equipment during PVC setup. Furthermore, the network equipment can count call blocking of SVC.
