基于移动Agent与主动网络网上选课系统

The On-line System of Selecting Courses Based on the Mobile Agent and the Active Network

学生大量集中于某个时间段进行选课时,服务器承受的压力不亚于DDOS攻击。通过使用移动Agent技术,在构建主动网络体系结构的基础上实现了网上选课系统。2008年6月的选课表明,系统通过分布式技术、利用廉价PC网络节点充当临时服务器,在资源利用和效率上达到了一个很好平衡点,对需要短期承受压力的系统有借鉴、推广意义。

The pressure born of the server is not second to the distributed denial-of-service （DDoS） attack when a large number of students are focus on a period of time for selecting courses. The on-line system for selecting courses is accomplished by using the mobile Agent technology and building the architecture of Active Network. The actual information of selecting courses on June 2008 shows the architecture has achieved a good balance on resource utilization and efficiency by the use of distributed technology in which low-cost PC network nodes are acted as temporary servers, which has good practicality and generality for the system to bear pressure on short-term.
