摘　　要：针对CSFQ算法存在的对TCP流的抑制及缓存策略等问题,提出采用ARED作为缓存管理的CSFQ改进算法A-CSFQ,并在多瓶颈链路下对其性能进行仿真。仿真结果表明,改进算法在保持CSFQ其他优点的基础上,显著减弱了对TCP流的抑制作用,提高了其对TCP流的公平性。This paper brings forward A- CSFQ algorithm based on CSFQ to solve the problem of CSFQ, such as its restraining effect on TCP flows and buffer management strategy. A - CSFQ uses ARED as its buffer management algorithm. It is simulated in multiple congested link network topologies. The simulation results show that the improved algorithm decreases its restraining effect and improves fairness on TCP flows based on keeping the virtue of original CSFQ algorithm.
