A system comprises a first asynchronous transfer mode switch, a second asynchronous transfer mode switch, and a system control module. The first asynchronous transfer mode switch and the second asynchronous transfer mode switch are interconnected with one another via a physical interface. The first asynchronous transfer mode switch is in communication with the with the second asynchronous transfer mode switch via a virtual connection on the physical interface. The virtual connection has a corresponding bandwidth. The system control module is in communication with the first asynchronous transfer mode switch. The system control module is in communication with the second asynchronous transfer mode switch via the first asynchronous transfer mode switch and the physical interface. The system control module dynamically controls the corresponding bandwidth of the virtual connection over time. The system control module is centralized for the first asynchronous transfer mode switch and the second asynchronous transfer mode switch. The physical interface has a corresponding utilization level and further wherein the system control module periodicallly and continuouly checks the utilization level to determine what the corresponding bandwidth should be. A process comprises creating at least one virtual path extending from a first location to a second location through at least one asynchronous transfer mode switch for a customer in response to a customer request, selectively destroying at least one selected virtual channel of the at least one virtual channel of the virtual path as needed, checking each selected virtual channel of the at least one virtual channel that is created with the connection admission control module of each asynchronous transfer mode switch that the virtual path extend through to determine whether the selected virtual channel will fit in the virtual path, and checking the customer contract and the time of day to determine necessary adjustments.
