摘　　要：随着网络的不断发展,传统的TCP拥塞控制机制已经不能很好地适应现有的网络环境;文中在分析了不同反馈信息的价值的基础上提出了一种新的基于路由器反馈的拥塞控制机制RSCP,部署方便,不需要额外包头;该机制创造性地提出了信号包的方法与路由器交换信息,并以公平带宽和公平剩余带宽为反馈信息,在以公平带宽为基点的基础上根据公平剩余带宽的变化调整发送速率,同时采用快速启动机制使连接能够快速达到公平带宽;仿真实验证明RSCP在单瓶颈网络中能取得高利用率、低队列长度和零丢包以及良好的收敛性能。Along with the development of the network, the traditional TCP congestion control system has not good to adapt to the existing network environment. This paper analyzes the different feedback the value of information put forward on the basis of a new router feed- back congestion control based on RSCP mechanism, deployment, do not need additional convenient haotou. This mechanism creative puts forward the method and the router signal hag, and exchange information in a fair bandwidth and fair surplus bandwidth for feedback informa- tion, with justice in the basis of bandwidth based on the change of the bandwidth according to fair remaining adjustment, and send the rapid rate of starting mechanism that links can quickly reaching a fair bandwidth. Simulation experiments show RSCP in a single bottleneck net- work can achieve high efficiency, low queue length and zero lost package performance, as well as good convergence.
