Centralized Directory Of P2P Model Based On Cloud Center

The popularization application of the computer technology makes people’ s life more convenient and fast, at the same time large amount of data produce d fill in people’s daily life. Ordinary computer processing these massive data has become very difficult, and the data processing requirements are also getting hig her and higher, not only to achieve accurate but also hope to quickly short waiti ng time. Peer to peer network (P2P) makes client and server structure (C/S stru cture) in the traditional server weakness in face of massive data processing and pa ralyzed with new ideas. Study and development of Peer-to-Peer network structu re model to solve massive data processing efficiency is low and massive data pr ocessing in network paralysis of the problem in Structure of the traditional clien t/server model (C/S model). The general concept model of Peer-to-Peer networ k structure is divided into a hybridmodel structure model, no structural model and structural model. Belongs to the structural model of centralized network has been widely used for a period of time inherent in various software applications, but as the model of software centralized network in the network number of us ersincrease and commercial value, related to the drawbacks of P2P gradually rev ealed, especially the user demand for network bandwidth upgrade, requirements of real-time data processing ability is more and more high and relatedbusiness documents copyright dispute problem.Cloud computing is a new technology in the recent period has obtained the fast development, various models and the application of cloud computing based on continuous research and use.According to the development of cloud computing to cloud storage technology, is to replace the old forms, cloud storage technology has been more and more users. IaaS, PaaS and SaaS three kinds of service model of cloud computing is becoming a mainstream service based on network service.Aiming at the problems, this paper presents a computing service cloud ba sed centralized P2P model, the model is to use cloud computing platform, the w hole model by using hierarchical super peer management, different levels betwee n nodes using the token passing information exchange. Model stratified structure will make not because at the same time the massive nodes in network operatio n and application access, Hierarchical model also makes the system structure clea r and easy to understand,for network fault detection and system maintenance hel ped. Network structure size can be controlled, according to the number of th e network users and instant increase or reduce, Make the system structure more reasonable. For the service patterns in a specific resource selection, path, node access and leave the specific measures are elaborated in this part. This paper through the experiments proved durable cloud storage service model of centraliz ed P2P cloud center can provide user based, can be used in the dynamic network environment and has good usability. The article also through the introduction of simulation examples of the ap plication ofcentralized directory P2P model based on cloud center, the centralized P2P models to compute the service based on the cloud of examples can be giv en a specific operating environment. The new electronic money bitcoin in actua1payment, showing that the integrity and robustness of network model calculates the P2P model under the environment of cloud. The whole process takes into account not only the ordinary transaction mode, also joined the borrowing behavi or cloud supervision, make the transaction process tend to be more practical mean s of transaction. For user level evaluation can ensure the transaction on the overa ll safety andfairness.
