An experimental ATM network featuring de-coupled modular control

An experimental asynchronous transfer mode (ATM) network spanning two cities is described. A novel architecture is employed in which the control processor for the switch is interfaced via an ATM link. It is suggested that this architecture offers a number of unique advantages over conventional switch designs for both network operators and manufacturers. These include flexibility in locating and dimensioning control processors and the opening of a new market in exchange controllers. The switch also features multiple discard and delay priority levels
