【摘要】 对当前高校选课系统的模式和高并发情形进行了研究,分析了造成此类问题的原因。介绍可大幅降低WEB服务器压力的、抢占加抽签任意组合策略的、任意流控型选课系统设计方案。以及如何利用线程池应对极端选课模式下的高并发用户,该方案相比传统的负载平衡型方案可大幅降低硬件投入和易于维护的优点。在此基础上开发出高适应性、高性能和安全选课系统。更多还原

【Abstract】 Researching on the system of university course selection mode and high concurrency situations,the causes of these problems are analyzed. the design scheme of wilfully flow control type course selection system which can reduce WEB server pressure is introhuced. This design scheme is based on strategies of draw combined with preemption arbitrarily. And how to use the high concurrent user thread pool to extreme selection mode, the scheme is compared to the traditional load balancing scheme can greatly reduce the hardware investment and is easy to maintain the advantages. Based on the,above which of high adaptability, high performance and safety of elective system are developed.更多还原
