网络已是人们学习生活不可缺少的一部分，如何能够准确、快速地检测出网络流量异常，并做出合理的响应，是网络正常运行的保证。本文提出改进的CUSUM流量异常检测算法，通过对CUSUM算法对网络流量进行检测，在警告判断条件和增加约束条件两方面进行改进。最后实验结果表明，CUSUM算法实现简单，在提高异常流量检测的误报率和漏报率方面有较大改进。

The network is an integral part in people living and learning. It is an assurance of a normal network running how to be able to detect the abnormal network traffic accurately and fast, and to make a reasonable response. This paper put forward the algorithm for an abnormal network traffic detection based on the improved CUSUM, it was improved through two parts of the warning judgement and improvement constraints according to the detection algorithm. Finally, experimental results showed that CUSUM algorithm was a simple, had a great of improvement in the aspects of improving traffic abnormal detection false positive negative rate.
