Research On Routing Technology Of Date Storage Based On P2P

ABSTRACT:With the increasing importance of information, data storage becomes more and more important. At the same time, the growing network users and PC system capacity is rapidly increasing, which makes people more aware of the importance of storage resources in client systems. P2P (peer-to-peer) technology provide new ideas and means for data storage in network, it can take advantage of the idle resources in PC systems. But in a huge amount of the PC systems and resources, how to effectively search and locate the resources is the key. Therefore, the routing algorithm using in P2P network storage has very important significance.This paper conducted a systematic and comprehensive analysis and summary in the routing algorithm in the P2P Research, and based on that, the author design physics-based information to improve Chord model. The model is a distributed P2P network storage system, this system is not under any central of servers and nodes control themselves in the network storage system. According to the physical information, all nodes are divided into different groups. Finally, the author implemented a simple data storage system based on this improved routing model; the system can complete storage and retrieval capabilities more efficiently.This model uses P2P technology in network storage and is innovative in design. First, based on the Chord model, it proposes the way that will reduce the delay by making the logical structure match the physical network. Second, the rational improve of the logical structure of Chord model. Finally, to reduce redundant information, and increase the effective routing table information. In the simulation, the experiment could reflect that the improved model is more efficient than the classic Chord model in search.
