Call Admission Control (CAC)

Figure 5-5: Traffic Management

When a SVC establishment request signaling is received from the originating terminal, CAC, or Call Admission Control, determines whether to accept that request. CAC checks the current usage of the network to determine whether the communication band and traffic quality requested by that SVC can be satisfied, then decides whether to establish the connection.

Usage Parameter Control (UPC)

UPC, or Usage Parameter Control, monitors whether the traffic of the user’s communication in progress has exceeded the band declared in the request for SVC establishment. This control is necessary to prevent deterioration to the quality of the communications of the user and other users in the network.

The ATM Switch employs a six-stage parameter control using the dual leaky bucket method.
