| 摘要: |
| 在高速分组交换网络中,分组调度策略和算法的设计是一个关键问题.由于网络分组调度策略有着多方面性能的要求,如何同时满足多个性能目标是当前的研究难点.基于比例公平性原则,提出了一种分组网络中的比例公平调度策略(proportional fairness scheduling,简称PFS),该调度策略综合考虑了网络效率、用户QoS要求和系统公平性等多维目标,对该策略进行了详细的分析和论证.比例公平调度策略可以广泛应用于分组网络调度策略的设计研究和改进. |

| Abstract: |
| The design of packet scheduling strategy and algorithm is one of the most important issues for the high-speed packet-switched networks. Because the packet scheduling strategy has multiple performance objects, how to reach multiple objects simultaneously is a difficult problem. Based on the proportional fairness principle, a proportional fairness scheduling (PFS) strategy in packet-switched networks is provided. The PFS integrates several objects, such as network performance, user抯 QoS requirement and system fairness.And the proposed strategy is analyzed and proved in detail.Moreover,the proportional fairness scheduling strategy can be applied to design and improve the packet scheduling strategy and algorithms in packet-swithched networks. |
