In this thesis, the advantages and disadvantages of the current prevalent congestion control algorithms are discussed in detail. Based on some general AQM algorithms such as RED, REM, RED/ ECN and RED/ BECN, an improved congestion control scheme is proposed.

本文在对当前几种流行的主动队列管理算法&RED，REM，RED/ECN以及RED/BECN进行详细的分析基础上，总结出当前拥塞控制算法的优势和不足，并提出了一种更优化的解决方案。

Backward ECN ( BECN) suggests a congested router to directly return the congestion information to the sender through ICMP source quench ( ISQ) messages to reduce the reaction time to congestion.

其中，后向显式拥塞指示（BECN）建议拥塞的路由器直接把拥塞信息通过ISQ返回给发送端，以减少对拥塞的反应时间。
