[摘要]：Round-robin-based packet schedulers generally have a low complexity and provide long-term fairness. The main limitation of such schemes is that they do not support short-term fairness. In this paper, we propose a new low-complexity round-robin scheduler, called Fair Round-Robin (FRR), that overcomes this limitation. FRR has similar complexity and long-term fairness properties as the STratified Round-Robin (STRR) scheduler, a recently proposed scheme that arguably provides the best quality-of-service properties among all existing round-robin-based low-complexity packet schedulers. FRR offers better short-term fairness than STRR and other existing round-robin schedulers. |
