摘要: 针对局域网流量性能,提出流量规一化概率,构建基于交叉熵的网络流量与容量关系模型,仿真并分析了流量规一化概率对网络性能的影响。与实际网络监测的流量指标进行了对比,给出流量规一化概率在TCP和FTP协议数据传输过程的误差。该分析结果能较好地应用于1 000 Mb/s及以上的局域网络及性能优化。

Abstract: Aiming at the flow of LAN,defining the flow normalization probability,a model on the relationship between flow and capacity,based on cross entropy,is built to simulate and analyse the impact of the flow normalization probability on network performance.By comparison of the simulated flow and the reality flow,in TCP and FTP protocol data transmission process,the error of flow normalization probability is presented.The results can be applied to optimize 1 000 Mb/s and above LAN.
