| 摘 要： | Claffy在1994年对1 h的主干数据分析的基础上,提出了基于时间驱动技术比基于报文驱动技术得出的抽样结果要差一些,但是二者之间的差别很小。为验证这个结论是否依然适用,以CERNET某2.5 G省网边界链路3个不同阶段连续1 h报文数据构成的Trace为对象,采用Claffy相似的方法,对报文长度分布测度进行了分析,获得了1组有关的结论,可以用于与网络测量和网络行为学有关的研究。

| Abstract: | Since drawn by Claffy in 1994,it has been well-accepted so far that the time-triggered techniques did not perform as well as the packet-triggered ones.Furthermore,the performance differences within each class(packet-based or time-based techniques) are small.Is this conclusion still suitable now? Based on three one-hour packet traces collected from a CERNET 2.5 G province net border link recently,we used a methodology similar to Claffy's and analyzed the metrics of packet size.Some interesting characters beh... |
