【摘要】 针对教育资源共享问题,设计了教育资源共享网络体系结构,定义了各层节点的功能。在此基础上,将层次环网络拓扑引入到节点组织模型中,详细给出了实现网络结构连接的方案。然后,基于层次环网络给出了一系列提高系统服务质量的策略,包括节点的加入/离开、代理、分布式资源检索策略。通过理论分析比较,证实了采用层次环网络的优势和相关策略的有效性。更多还原

【Abstract】 Focus on the problem of education resources sharing,this paper designed a resource sharing network architecture and defined the functions of various kinds of nodes.Based on this architecture,introduced a logical topology network——HRN,and gave implementation details of connecting two nodes.Then,to improve the QoS of this system,proposed a series of key strategies,which included the strategies for node joining or leaving,proxy strategy and the strategies for distributed resource retrieval.Finally,confirmed the advantages of the logical HRN network and the effectiveness of these strategies by theoretical analysis and comparison.更多还原
