摘　　要：TCP/IP已成为事实上的Internet标准协议 ,作为Internet扩展的非对称网络环境也必将采用它。通过对非对称链路上拥塞控制问题及当前主要算法的讨论 ,针对其中存在的不足 ,基于目前的TCP拥塞控制机制 ,提出了一种适于非对称链路的SACK改进算法 ,提高了多个丢失分组的重传效率和网络吞吐量。TCP/IP is actually the standard transport layer protocol over Internet as well as the asymmetry network environment.In this paper,the problem on congestion control is analyzed and the main solutions are discussed in the case of asymmetric links.As the solution,a novel SACK-based congestion control algorithm is given and tested through simulations,which improved the efficiency of packet retransmission as well as the throughout of the whole network.
