随着计算机网络的持续快速发展,各种网络需求不断涌现,拥塞控制成为保证网络的稳定性和鲁棒性的重要因素,拥塞控制的发展要求网络本身也要参与其中.传统的端到端机制不能解决所有的拥塞问题,作为主动管理队列算法的REM原算法由于对RTT的不精确估计导致不能准确反应网络中拥塞状态.根据控制论中将链路价格化的方法,对REM算法的进行了改进,提出了新的拥塞控制机制.仿真实验表明,该方法能有效减少包的丢失,提高系统性能.

With the rapid development of Internet,various applications based on the Intemet have emerged.The congestion control becomes a most important protocol which improves tlle Intemet's stability and robustness.Its development requires network to manage itself.The traditional end to end strategy can not solve all congestion problems.As a result of imprecise estimate on RTT,original REM is not able to accurately reflect the congestion state.Based on the cybernetics and REM algorithm,an improved AQM algorithm and a congestion control strategy are proposed.The simulation result shows that the new one can effectively decrease the packet loss rate and improve network performance.
