摘要
网络流量特征分析是提高网络性能的基础.其自相似特征是一个普遍存在的现象.通过对主干链路上的流量进行基于流的流量特征的分析,结果表明流间隔时间序列在小时间尺度上的自相似程度较弱,而大时间尺度上的自相似程度较强.进一步的分析表明,流的大小以及ICMP流对流的自相似特征有显著的影响,特别是流大小为1个包的流对其影响更大.
The analyzing characteristic of network traffic is the base to prompt network performance. The self-similarity is a common characteristic of network traffic. Through the analyzing characteristics of backbone network traffic at flow level, it shows that the self-similarity of the time series of flow intervals at small time scales is weaker whereas it is stronger at large time scales. The further study shows the size of flows and the ICMP flows apparently affects the self-similarity. Especially, those flows of one packet have larger effects.
