[Abstract]:With the popularization of computer technology, people's life is convenient and fast, and a great deal of data and information are produced at the same time in people's daily life. It is very difficult for ordinary computers to deal with these large amounts of data information, and the demand for data processing is becoming higher and higher, not only to be accurate, but also to quickly wait for a short time. The research and application of peer-to-peer network structure model can solve the problems of low efficiency of mass data processing and network paralysis caused by mass data processing in the traditional client / server model structure (C / S network model structure). In general, the structure of peer-to-peer network model is divided into three types: hybrid model, unstructured model and structured model [1]. Centralized Peer-to-Peer Network, which belongs to the structured model, has been widely used in various software applications for a period of time, but with the increase of the number of users and the improvement of commercial value of the centralized Peer-to-Peer Network Model software in the network. The disadvantages of P2P are gradually revealed, especially the increasing demand for network bandwidth, the increasing demand for real-time processing of data and the copyright disputes related to commercial documents. Cloud computing, as a new computer technology, has been developed rapidly in recent years, and a variety of cloud-based models and applications have been continuously studied and used. Cloud storage technology developed by cloud computing is replacing the old storage technology, and cloud storage technology is getting more and more users' favor. Services based on cloud computing IaaSU PaaS and SaaS are becoming the mainstream of network services. In view of the above knowledge background and technology, this paper proposes a centralized P2P model based on cloud computing services. The model uses cloud computing as the core platform, and the whole model adopts the management mode of hierarchical super nodes. The nodes between different levels use tokens to transmit exchange information. The hierarchical structure of the model will not result in network paralysis due to the massive nodes accessing the application operation simultaneously. The layered model also makes the architecture clear and easy to understand. For the network fault detection and system inspection and maintenance to play a role in helping. The size of the network structure can be controlled, according to the number of users who use the network, the structure of the system can be increased or decreased immediately, which makes the structure of the system more reasonable. The specific measures such as resource selection, path judgment, node access and departure in the service mode structure are the specific parts of this paper. This paper proves that the centralized P2P model based on cloud center can provide the persistent cloud storage service for users, and it can be used in dynamic network environment and has good availability. By introducing the cloud-centric centralized directory P2P model, this paper gives an example of the practical maneuverability of the centralized P2P model based on cloud computing services. Through the payment of the new electronic currency bitcoin in practice, it shows the robustness of P2P model and the integrity of network model in cloud computing environment. The whole transaction process not only takes into account the common trading model, but also adds the cloud regulation of lending behavior, which makes the transaction process more close to the actual trading methods. The evaluation of the user level can ensure the overall security and fairness of the transaction.
