Abstract:
An ATM exchange in which a plurality of connections are established and a plurality of processes arise with respect to the plurality of connections, each having a transmission rate, the ATM exchange comprising:a priority computing circuit which computes a priority of a process according to a transmission rate assigned a connection to which the process is associated; a priority comparing circuit which compares a plurality of priorities corresponding to the plurality of processes to select a process having a higher priority among the plurality of processes; a processing circuit which carries out the selected process; and a managing circuit that recognizes a process relating to one of the plurality of connections and provides notification of a process request to the priority computing circuit wherein the managing circuit comprises: a queue registering circuit coupled to the plurality of connections and recognizing processes from the plurality of connections; a plurality of queues, to one of which the queue registering circuit assigns a particular process; and a plurality of queue managing circuits, each associated with one of the plurality of queues, updating the queue, and providing requests from the queue to the priority computing circuit.
