A new integrated unicast/multicast scheduler for input-queued switches

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.
