摘　　要：Peer-to-Peer模型是一种新型的体系结构模型,许多优势有待于进一步发掘,拥有广阔的应用前景。首先指出基于模式的高可扩展的P2P系统可以满足P2P研究领域中对语义支持的需求以及对高可扩展性的需求,是P2P数据管理的发展趋势;通过综述基于模式P2P系统和高可扩展性P2P系统的研究现状,指出现有P2P数据管理研究项目分别从P2P网络的语义重叠网络和重叠网络两个方面改善P2P网络的性能和服务质量,两者之间缺乏衔接,各自的研究成果无法直接结合产生基于模式的高可扩展的P2P系统;给出基于模式的高可扩展P2P系统的研究目标,分析该方面的初步研究成果;最后指出未来需要进一步研究的问题。Peer-to-Peer is a new model of architecture, which has a lot of advantages to be further discovered and has a cheerful application future. Firstly, the paper points out that the schema-based highly scalable P2P system can satisfy the needs for both semantic support and high scalability in P2P research area, and so it is the trend of P2P data management. Then, through the survey on the current schema-based P2P systems and the highly scalable P2P systems, the paper points out that the current P2P data management research projects improve the efficiency and quality of service of the existing P2P network from two facets： the semantic overlay and the overlay, and the lack of connection between them makes it too difficult to generate the schema-based highly scalable P2P system from them. After that, the goals of the schema-based highly scalable P2P system are given, and the initial result of this research area is analyzed. Finally the issues which need to be further studied are pointed out.
