A New Integrated Unicast/Multicast Scheduler for Input-Queued Switches

The 8th Australasian Symposium on Parallel and Distributed Computing (AusPDC'10), Brisbane, Australia, 18-22 January, 2010.

Researchers have thus far considered scheduling unicast and multicast traffic separately, and have paid little attention to integrated schedulers. To this end, we present a new integrated scheduler that considers both unicast and multicast traffic simultaneously and also addresses key shortcomings of existing approaches. Specifically, we outline a scheduler that achieves 100\% throughput, and unlike existing schemes, do not require a tuning knob. Moreover, from our extensive simulation studies, we show that it works well in uniform, non-uniform and bursty traffic scenarios.
