Low complexity scheduling algorithm for a buffered crossbar switch with 100 throughput

摘要

Scheduling techniques for use with buffered crossbar switches, without speedup, which can provide 100% throughput are described. Each input/output may keep track of the previously served VOQ/crosspoint buffer. The queue lengths of such VOQs and the queue lengths of VOQs corresponding to a uniform probability selection output (e.g., from a Hamiltonian walk schedule) are used to improve the schedule at each time slot.
