Scheduling algorithms for Virtual Output Queuing switches

Baranowska A., Kabaciński W.

In this article we have given an overview of different scheduling algorithms for virtual output queuing switches. We have also proposed three new scheduling algorithms for VOQ switches called Hierarchical Round-Robin Matching (HRRM), Matching Matching with Random Selection (MMRS) and Maximal Matching with Round-Robin Selection (MMRRS). Evaluation of the proposed algorithms was performed under Bernoulli and bursty packet arrivals with uniform and non-uniform distributions to output ports. Performance evaluation of the proposed algorithm under different traffic models is given and compared with other well-known algorithms. The simulation results show that MMRRS and HRRM achieves 100% throughput and low MTD for high loads.
