Abstract
Ports of an ATM (Asynchronous Transfer Mode) switch are consolidated into cluster modules to increase the aggregate throughput of the switch. Packets are routed between cluster modules using an intercluster switching network. The intercluster switching network includes a plurality of input channels and output channels. During a switch cycle, a maximum of 'K' packets are delivered to each of the output channels of the intercluster switching network. This maximum of 'K' packets is a speedup per cluster module that is shared between ports of each cluster module. Consequently, each output port of a cluster module operates with a peak speedup of up to 'K' packets per switch cycle thereby increasing the aggregate throughput of the switch.
