The system discussed before is analysed and modeled by means of using Unified Modeling Language. On the basis, the distributed Web Service frame of the system and distributed database structure is studied in detail. Meanwhile, the function of system, such as user management and human basic information management and so on, is implemented in detail.

Because DHT methods just provide exact-match query facility, not satisfying the flexible query requirements, the paper also discusses a scalable, flexible multi-keyword resource located technology. The paper proposes the filtering conjunctive operation scheme similar with distributed database. It also includes an incremental search over the peers to decrease the query latency and bandwidth consumed. Lastly we investigate the popularity of user search behaviors and provide the cache strategy to reduce the overhead associated with operations spread across the wide area to provide the efficient resource query and access in scalable P2P system.

由于分布式哈希路由算法只能提供精确的资源定位，不能满足人们灵活的查找需求，因此本论文也讨论了一种便于扩展，灵活的多关键字资源搜索与信息服务技术，提出类似分布式数据库的过滤器连接算法，并采用增量式查找算法减少查询延迟及带宽消耗，利用缓存策略加速查询，以期为大规模的P2P网络提供高性能的资源搜索与数据访问服务。
