CERNET网络业务的自相似性及性能分析

SELF-SIMILARITY OF CERNET TRAFFIC AND THEIR PERFORMANCE EVALUATION

针对真实网络业务的自相似性问题 ,分析了 CERNET网络业务数据 ,证实 CERNET网络业务具有典型的自相似性 ,并用这些数据对自相似业务下的队列系统性能进行了仿真研究 ,结果表明 ,定标律对理解自相似性给网络性能带来的影响具有重要意义 .

In recent years many measurements have shown that the real traffic has self similarity.This paper discusses the analysis of CERNET traffic made by us,and the result has also shown the existence of self similarity in CERNET.We also completecl a simulation study of queueing performance using CERNET traffic data and found that the Scaling Law playsa key role in understanding the impact of self similarity on network performance.
