Abstract

Input queuing has advantages for building ultra-broadband ATM switches with the throughput beyond 100Gb/s because it imposes minimal memory bandwidth requirements. Using a novel multi-tag-queue input module and a novel matrix-unit-cell-scheduling module, our input queue-based ATM switch avoids head-of-line blocking and provides almost 100% utilization. In a 32-port configuration, the switch can deliver an aggregate throughput of 128Gb/s.
