Accurately modeling the Internet topology
Based on measurements of the internet topology data, we found that there are two mechanisms which are necessary for the correct modeling of the internet topology at the autonomous systems (AS) level: the interactive growth of new nodes and new internal links, and a nonlinear preferential attachment, where the preference probability is described by a positive-feedback mechanism. Based on the abo...
متن کاملUnderstanding the internet topology evolution dynamics
The internet structure is extremely complex. The Positive-Feedback Preference (PFP) model is a recently introduced internet topology generator. The model uses two generic algorithms to replicate the evolution dynamics observed on the internet historic data. The phenomenological model was originally designed to match only two topology properties of the internet, i.e. the richclub connectivity an...
متن کاملFluctuation-driven dynamics of the internet topology.
We study the dynamics of the Internet topology based on empirical data on the level of the autonomous systems. It is found that the fluctuations occurring in the stochastic process of connecting and disconnecting edges are important features of the Internet dynamics. The network's overall growth can be described approximately by a single characteristic degree growth rate g(eff) approximately 0....
متن کاملVisualizing Internet Topology Dynamics with Cyclops
The Internet AS-level topology is a highly dynamic structure that evolves over time under diverse technical, economical and social forces. Up to now the few efforts on topology visualization have taken only static snapshots of the topology graph. In this poster, we present Cyclops, an interactive visualization tool that highlights the changes in the Internet AS-level topology. We use case studi...
متن کاملA Survey on Internet Topology Modeling
As the basis of Internet development and exploitation on higher levels, the Internet topology modeling starts from the random model to the hierarchical model. Then it developed to a more realistic one, scale-free network model. Many characteristics of topology are analyzed with the corresponding metrics, including power law. Moreover, the related work on the current topology models, topology ge...
