0引言为了提高计算机网络的可靠性,必须要使电脑系统在规定的时间内进行最高效的数据传输,可以采用信息熵的分析方法,让硬件系统在规定的条件下完成指定功能的表达。造计算机的硬件设备往往对对计算机网络的稳定性影响较小。在一般的情况下,计算机硬件设备的性能越高,计算机的工作水平越高,网络环境的可靠性就会越高。1信息熵在网络异常检测中的常用技术方法 0 foreword In order to improve the reliability of the computer network, must make the computer system carry on the most efficient data transmission within the stipulated time, can adopt the entropy analysis method, let the hardware system finish the designation of the function under the specified conditions. Hardware devices made of computers tend to have less impact on the stability of computer networks. Under normal circumstances, the higher the performance of computer hardware equipment, the higher the working level of the computer, the higher the reliability of the network environment. 1 information entropy in the network anomaly detection technology commonly used method
