BECN

The characteristic relations has becn developed and it is very suitable to use the Courant difference method with the guarantee condition of convergence.

经特征变换后，采用收敛和稳定性均有保证的Courant差分格式进行数值计算，克服了对称差分格式在处理线路边界条件时的困难。

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。

Backwards Explicit Congestion Notification ( BECN) Rm-cell may be generated by the network or the destination.

后向明确拥塞通知（BECN）源管理（RM）信元可以由网络或目的设备生成。

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。
