摘要
本文提出并分析了一种连续值反馈闭环拥塞控制方案.证明了它的无振荡稳定性,推导出使得系统性能达到最佳的参数设置.所谓最佳是指:系统达到稳定的速度很快;稳态下,系统的带宽利用率最大,并且延迟最小.文中的仿真结果表明,该方案在各种情况下运行正常,且性能优于其它的一些连续反馈控制方案.
A new multivalue feedback closed-loop control algorithm for handling and preventing congestion in highspeed networks is proposed and analyzed. The asymptotical stability (oscillation-free) of this algorithm is proved. The issue of optimal parameter design which gives the optimal transient behavior (in the sense that the asymptotic approach to steady state is fastest), and the optimal steady-state behavior (non-oscillation, maximum of throughput and minimum of delay) is presented. Extensive simulation results show the robustness of the algorithm and the better performance than other multivalue feedback closed-loop control algorithms.
