摘　　要： 探讨利用对等网络技术(P2P)来构建一个选课系统,将学生选课的处理任务分发到不同的网络节点,解决原有选课系统出现的单点服务瓶颈问题.选课系统采用两层的半中心化结构,利用JX-TA所定义的服务来构建学生选课服务组,不同服务组可以为不同的学生提供选课服务,以此来减轻单个服务器的负担,达到有效的负载均衡. In order to avoid the performance bottleneck of having a single server system in the existing System of Selecting Courses, this paper proposes a new approach for constructing P2P network based on JXTA platform. The framework for the System of Selecting Courses based on JXTA is structured around a semi-centralised P2P network model-super peers and ordinary peers, super peers are generally more powerful in terms of connectivity, bandwidth, processing, and provide Selecting Courses Service to students. Ordinary peers are connect-ed with super peers, and use the Selecting Courses Service published by the super peers to finish the courses selection. This architecture based on JXTA can lighten the burden of the server greatly and reach the load balancing effectively.
