Research Plan on Scheduling Algorithms for WDM-PON under SUCCESS-HPON Architecture

• To provide better fairness among all traffic flows both up- and downstream, we need more systematic approach in designing scheduling algorithms, hopefully based on some quantitative analysis like fairness bounds. For systematic approach and quantitative analysis, it's critical to extend the definition of fairness to multiple-server case.
• Deficit Round-Robin (DRR) fair queueing and its many variations could be good starting points in that they could naturally support variable size packets and rather simple to implement.
