| 摘 要： | 本文提出了一种支持分级服务和最小带宽保证的改进TCP算法－DSAS－TCP，通过对TCP算中慢启动阈值和最小拥塞窗口的分级设置来使不同等级连接的平均吞吐量产生分级，并保证用户的最小带宽需求。通过理论分析和仿真实验验证了该算法的有效性。

| Abstract: | This paper proposes a modified TCP algorithm(DSAS TCP)that supports both differentiated services and assured services The algorithm differentiates the average throughput of the connections with different quality of service requirement by differentiating the values of the slow start threshold hopping coefficients and supports assured services by using the minimum congestion window The theory analysis and simulation results prove the validity of the algorithm |
| |
| Keywords: | transmission control protocol differentiated services hopping coefficient minimum congestion window throughput |
