摘要

互联网宏观拓扑结构下时延特征的研究对互联网结构与性能的理解具有重要作用。择取CAIDA Ark项目下分别位于4个不同地区的探测数据，提取网络时延与通信直径，发现网络时延与通信直径关系很小且超过70%的有效路径中存在支配时延。经分析，正是支配时延的存在影响了网络时延与通信直径的关系。对支配时延链路两端进行地理映射，发现支配时延以较高概率出现在同一国家同一城市某一链路传输之间。在此基础上，得出链路两端距离小于5 000 km的支配时延主要由排队时延组成，而链路两端距离大于5 000 km的支配时延主要由传播时延组成的结论。

Abstract

Research on the delay of the Internet under marcrotopology plays an important role in comprehension of Inter-net architecture structure and performance. Using effective samples in four different regions authorized by CAIDA Ark and getting network delay

there is little relationship between network delay and communication diameter and the number of the effective paths happening dominant delay is over 70%. The analysis presents that it is dominant delay that affects the relationship between the network delay and the communication diameter. The geographic mapping of the link hap-pening dominant delay supposes that the dominant delay happens frequently in the link across one city in a country. Fi-nally

the conclusion is draw that queue delay is the major composition of the dominant delay for a short range(less than 5 000 km)

whereas the propagation delay is the main factor for a long distance(greater than 5 000 km).
