(Peer-to-Peer, P2P for short) is considered to be a technique, but should be considered more as a thought. It has the potential to change the basis of Internet and its advantages make it widely used. This not only invoked researchers' passion in information technique areas, but also inspired expectation on PLP from normal people. Now applications based on P2P are popular. P2P technique leads the network computing mode from centralization to distributi. That is to say the core network applications transfer from centralized server to edge end users. All the network nodes can establish P2P sessions. This high-leveled sharing behavior in the Internet and make people motivated to take part in to the network.Advantages of P2P is (1)it makes people connected directly through Internet. P2P makes communications on the Internet more easily, more sharable and more directly. It gets rid of middleware.(2) P2P is the application that you can connect directly to other computers to exchange files in stead of access to server to browse and download in the past .(3) The other important attribute of P2P is the change from centralization to un_centralised and give the rights back to end users. (4) Up to now, the most important advantage of P2P is to increase network use ratio of users. and is to access to more resources.P2P have many advantages, but it also have some connatural defects,the main defects are: it is difficulty to manage by P2P,and that conventional C/S is easy to manage in central server;because the node of P2P is disperseible,so it can free enter or exit network.,the answer is the band and information is instability,so P2P'policy is very complex in security and copy.But CDN can conquer these defects,but its defect is to need hardware,but the hardware is expensive;and the CDN also have the connatural defect of C/S,the central server is choke point.For settling these problem,a new architecture will be applied in this thesis, it make up of dynamic autonomic system and structural source server. In autonomic system allow dynamic delamination between source server and agent server will apply structural model.Base on different work character, it must be charged with different mission will distinguish different object, and apply different structural model to improve high effective data transfer and source share. A routing action often includes determination of arriving destination of the best of the route and along finded the best of the route transfer information grouping. In this thesis will base on constructed new network structure to form corresponding dynamic routing algorithm; base on high dynamic constructed dynamic structural diffused inner system routing algorithm in autonomic system.In this thesis,the innovation of point is :1. build a new hybird architecture,it combine P2P and CDN'advantage..2. in autonomic system allow dynamic delamination, apply architecture of tree,and set up super node,it save information of other nodes in network.3. apply a topology of graph between source server and agent server.4. apply a particular routing and search algorithm.5. adding a node of algorithm have a index,it is spare loading of power, and base on this index node offer its source to network,to dynamic delamination。... |
