摘　　要：基于非中心化思想的P2P技术发展迅猛。文章分析了P2P覆盖网的4种拓扑结构与算法;包括:集中目录式非结构化拓扑结构、全分布式非结构化拓扑结构、半分布式非结构化拓扑结构,以及全分布式结构化拓扑结构。并以集中目录式非结构化拓扑结构为基础,设计了一套计算力共享系统,以针对海量地球物理数据的处理。该系统结构简洁、新颖、成本低,研发意义显著。P2P systems, based on decentralization, are being developed very fast. This paper analyses P2P overlay network s four main topologies and algorithms, including centralized unstructured topology, decentralized unstructured topology, partially decentralized unstructured topology and decentralized structured topology. Then, based on centralized unstructured topology, it designs a new kind of CPU shared system, which is designed for jillion geophysical data processing. And this system has typical features of st...
