Analysis And Research, P2p Networks Based On Opnet

Nowadays, information technology develops quickly, the network structures and scales become complicated. With continuously extending in scope and scale of the applications, it is difficult to program and design the network, the development of the network protocols, and the design of the network equipments also. So there has an urgent needs of means in science urgently to reflect and predict the function of the network, the system simulation technique emerge with the tide of the times. Is 20 near in the last years the system simulation technique develops particularly, the network simulation, the intelligence programming, network optimizing and managing become hot issues of the data network domain. The application of system simulation techniques can raise the credibility and accuracy of the network programming and designs, furthermore it can lower the network investment risk clearly, and reduce the investment waste. System simulation technique will become the link of the programming and designing of network indispensability.The simulated OPNET network software has provided powerful exploitation environment for the network simulation , the main body of a thesis has been submitted (Hierarchical Aggregation P2P NetworkRouting Model , HARM) classifying concentrating the dyadic P2P network route model, has been a model's turn to be a Internet topology frame-based P2P network route model, Structuring the purpose being a model's turn is numerous and repeated for going ahead in HARM basis build one apply to network (WAN) broad region high-performance , height are available , loads balance , dynamic P2P apply platform. And be platform's turn to be located in application , suppose logic topology structure by building a layer on Internet physics topology basis owing to that Haxi is encircled by region structure (Hash Ring's) the systematic P2P route algorithm, builds up a P2P network route model having complete distributed structure thereby effectively in being put into use on the person owing to structure-rization. Owing to that the HARM model relevance function index has carried out the network analogue test, and, the node adds system...
