基于非结构化P2P网络的地形数据存储系统

A Terrain Data Storage Model Based on an Unstructured P2P Network

  • 摘要: 为了提高三维地形漫游系统获取数据的速率,根据地形数据的特点和非结构化P2P网络的优点,提出了一种基于非结构化P2P网络的地形数据存储系统(unstructured P2P-based terrain data storage system,UPTDS)。与采用传统存储服务器模式的地形数据服务系统相比,系统搜索效率得到了提高,消除了服务器的性能瓶颈问题。

     

    Abstract: In order to improve the speed of obtaining terrain data in 3D terrain roaming systems,an Unstructured Peer-to-Peer Terrain Data Storage System(UPTDS) is proposed on the principle of terrain data characteristics and Unstructured Peer-to-Peer System's virtue.Massive terrain data is stored in the peers of the UPTDS.And UPTDS is divided into two layers,data sever layer and data download layer,according to peer's property and function.The two layers are incharge with data searching and supplying data respectively.Compared with the traditional storage system,UPTDS advances the searching efficiency as well as eliminates server performance bottlenecks.
