摘要: 为了更好地实现分布式构件库之间的信息共享与交互,使复用者更加便利地在多库中进行构件查找、提高查准率,提出一种基于P2P的分布式软件构件库检索机制。采用分层混合对等网络体系结构,其中的超级节点可以自动地对检索条件进行重构,从而使复用者可以透明地在多库中进行检索。该机制可以有效提高分布式构件库间的信息共享性,以及检索的便捷性与有效性。

Abstract: In order to achieve better resource sharing and interaction among distributed component libraries, make reusers search components in multiple component libraries more easily and improve the accuracy, this paper puts forward a distributed software component library retrieval mechanism based on P2P. The mechanism uses a mixed-layered architecture of P2P network. The super nodes can automatically refactor the query conditions. Thereby the reusers can be transparent to retrieve components in multiple libraries. The mechanism can enhance information sharing of distributed component libraries and increase the convenience and effectiveness of retrieval.

Key words: Peer-to-Peer(P2P) network, distributed query, software component library, query conditions refactoring, routing query algorithm
