| 摘 要： | 针对核心无状态公平队列调度(CSFQ)的丢包算法不适用于TCP流的问题,提出了一种改进算法my-CS-FQ,能够根据网络状况动态地调整TCP流和UDP流各自的丢包行为,解决TCP流与UDP流的带宽分配公平性.大量仿真实验结果表明my-CSFQ算法能够提高TCP流同UDP流竞争网络资源的能力,更有效地利用链路带宽,提高网...

| Abstract: | CSFQ(core stateless fair queuing) can achieve as well fairness in bandwidth allocation as that implemented by stateful networks.However,its dropping algorithm is derived from non-responsive flows such as UDP flows,and does not suit TCP flows.In accordance with the drawback,the paper proposed a method that can enhance CSFQ algorithm,which dynamically can regular the dropping probability based on network condition among TCP flows and UDP flows,the fairness of bandwidth allocations between TCP and UDP is well ... |
