我研究生阶段研究定的方向是网络拥塞管理，而我研究RED算法也有挺长时间了，很久以前就有解析NS中的队列管理算法RED的源代码（red.cc&red.h）的想法，借寒假有时间，匆匆写了一下。有些东西自己也没完全弄懂，但是对于困惑于如何修改RED算法的同学来说，应该有很大的参考价值。

　　本文档首先分析了RED算法涉及参数的含义，然后给出了主要函数的作用，最后对主要函数的源代码进行了分析。

　　希望本文档对你有用。

-I set the direction of post-graduate stage of the study is to network congestion management, but I have studied the RED algorithm also has quite a long time, long ago have resolved NS in the RED queue management algorithm source code (red.cc &　red.h) the idea, by winter have the time to rush to write a bit. Some things they themselves have no fully understood, but for the confusion on how to modify the RED algorithm for the students, it should be a great reference value. This document first analyzes the RED algorithm is related to the meaning of the parameters, and then gives a major role in the function and finally the main function of the source code analyzed. Hope that this document useful to you.
