Multi-Channel Deficit Round-Robin Scheduling for Hybrid TDM/WDM Optical Networks

Sathiyanarayanan, M. & Kim, K. S. (2012). Multi-Channel Deficit Round-Robin Scheduling for Hybrid TDM/WDM Optical Networks. 2012 IV International Congress on Ultra Modern Telecommunications and Control Systems, pp. 552-557. doi: 10.1109/ICUMT.2012.6459727


In this paper we propose and investigate the performance of a multi-channel scheduling algorithm based on the well-known deficit round-robin (DRR), which we call multi-channel DRR (MCDRR). We extend the original DRR to the case of multiple channels with tunable transmitters and fixed receivers to provide efficient fair queueing in hybrid time division multiplexing (TDM)/wavelength division multiplexing (WDM) optical networks. We take into account the availability of channels and tunable transmitters in extending the DRR and allow the overlap of `rounds' in scheduling to efficiently utilize channels and tunable transmitters. Simulation results show that the proposed MCDRR can provide nearly perfect fairness with ill-behaved flows for different sets of conditions for inter-frame times and frame sizes in hybrid TDM/WDM optical networks with tunable transmitters and fixed receivers.
