Design and Research on the Special System Architecture for Peer-to-Peer Distributed Storage System Based on Node Grouping

The organization pattern of P2P (Peer-to-Peer), has become an important form of internet application of new generation because of its such features, as good expansibility, fault tolerance and high-performance. The persistent data storage is the key to inhibiting the development of global storage system, and is also difficulty issues of the research.This paper describes a design idea and a system architecture of distributed storage system established on P2P in detail, and proposes an effective mechanism according to resource topic and predicted network distance for node grouping, and verifies the persistent data storage performance of P2P global storage system.
