P-Grid:一种高效的自组织P2P系统

P2P（peer to peer）技术在分布计算时代发挥着越来越重要的作用，但在数据管理方面，P2P的应用表现出较大的局限性。作为一种快速高效的P2P信息系统P-Grid，它能够极大地减少其它P2P系统所需要的网络带宽。P-Grid系统的构造和维护严格依照本地交互的随机算法，即使在不可靠的节点也能提供可靠的访问，并且能够较好地衡量存取和通信代价。

P-Grid: Efficient self-organizing P2P system

In recent years, peer-to-peer systems are driving a major paradigm shift in the era of genuinely distributed computing. But it shows up also some of the limitations of current P2P information systems with respect to their ability to manage data efficiently. P-Grid, a scalable access structure that is specially designed for peer-to-peer information systems is introdnced. P-Grids are constructed and maintained by using randomized algorithms strictly based on local interactions, reliable data access is provided even with unreliable peers, and scale gracefully both in storage and communication cost.
