| Abstract(in English) | Measurement studies of the Internet topology have revealed that the degree distribution follows a power-law. That is, the probability P(k) that a node has k outgoing links follows P(k)～k^<-γ>. Many methods to generate power-law topologies are proposed, however, structure of the actual ISP topology and sturcuture of the model-based topology differ from each other even if they have the same degree distribution. Besides, it is known that the power-law degree distribution does not determine traffic-level behaviors in the Internet topologies. In our previous work, we investigate packet-level delay behavior of topologies having power-law degree distribution. As a result, we revealed that end-to-end packet delay distribution of ISP topology has a long-tail characteristic caused by modularity structure of ISP topology. In this paper, we investigate the long range dependence (LRD) in time series of queue length on real ISP topology and model-based topology. Our results show that ISP topology prevents queue length from fluctuation against increased traffic. |
