A Research Of Internet Physical Properties And Their Models Based On CAIDA Data Analysis

With the high-speed development of the computer, Internet has already become the biggest computer network in the world at present,but it is increase continuously to grow in intensity , become qualified leap space-time and the region's " World Wide Web ". Then what kind of network is Internet network on earth? Whether we can define it into regular network , random network or complicated network ; This text passes and carries on the research of the hops from statistics of true data of Internet network, is based on this and draw some results of possessing the characteristics of statistics of the actual meaning. But Internet innate different person who construct, dynamics, development non-getting centralized and huge scale bring to topological modeling enormous to challenge nowadays. Internet topological modeling remains an open question so far, occupies the important position while studying in the computer network.This chapter is with Internet network background and introduction of relevant knowledge of CAIDA data at first, therefore launch various kinds of models of the topological structure chart of survey and state complicated Network Communications behavior, several kinds of classics which have enumerated the complicated network propagate models and Network Communications propagate behavior application. After putting to CAIDA data analysis in order , counting filtering through the author , summarize some laws of possessing the characteristics of statistics of the actual meaning, prove network topological diameter in what range change roughly , and the network topological diameter can reach density of network than inverse ratio relation fully, Can be found out through a lot of data analysis, the result that the data draw is accumulating and will often describe out some physics characteristics of Internet network constantly, thus set up some Internet networks topological model, the setting-up of Internet topological model is the foundation of Internet systematic model, the meaning of topological modeling reflecting therefrom, it is a meaning of Internet modeling that we can say too, is it analyse , predict , make policy or control as one tool people with their to Internet to come. What the topological part in Internet model is portrayed is Internet characteristic on the macroscopic, reflect a kind of overall trend, so their application is all launched on great yardstick.
