摘要
传统的基于流量的网络报警系统往往根据系统配置的固定阈值来判断当前网络流量是否正常,通过运用统计学和预测学对网络流量预测方法进行研究,提出了一种能根据网络实际流量状态自己调整阈值的新型网络报警机制,能有效地发现网络流量异常,从而为评估和优化网络性能提供有力的依据。
Traditional network alarm system which based on traffic usually sets fixed threshold to determine whether the current network traffic are at normal situation. After researching on network traffic forecasts by using statistical arithmetic method, a new alarm mechanism is put forward, which will adjust the threshold automatically as well as send alarm messages according to the real network traffic states. Such kind of mechanism will find the abnormal states of the network traffic, sequentially provide strong evidences to evaluate and optimize it.
