摘要： 提出了一个面向TCP流属性的非对称性测度，包括该测度的定义和计算方法。并基于这个测度对CERNET的一个千兆省网边界的实际数据进行了分析。分析工作从流长度(报文数)和流字节数2个属性角度展开，利用一组函数对这些流属性的非对称测度进行了统计和分析，获得了一组有关的结论，可以用于与网络行为学有关的研究。

Abstract: An attribute-oriented asymmetric metrics for TCP flow is proposed, including the definition and the way of calculation, with which and after being rebuilt to TCP flow, two traces of IP packet sniffed from a gigabyte backbone boundary of CERNET are analyzed on the attributes of TCP flow length (packet number) and flow bytes. Some interesting characteristics behind the flow are obtained, which can be used for network behavior research.
