高并发访问下的移动Web前端浏览性能优化研究

Research on Optimization of Mobile Web Front-End Browsing Performance Under High Concurrent Access

为了提高浏览移动Web前端的流畅性,提出了一种高并发访问下的移动Web前端浏览性能优化方法。通过收集和计算移动Web链路的CPU负载特征值、内存负载特征值、磁盘负载特征值和业务流负载特征值,构建移动Web业务流训练样本集,判断移动Web前端的负载状态。根据移动Web负载的过载序列和轻载序列,获取负载均衡分配节点的状态,结合移动Web负载均衡分配的时间延迟状态和带宽状态,利用带宽等级优化均衡分配移动Web负载。利用通信子站的连接关系计算数据传输路径的可利用率,通过计算用户权限验证时延得出用户浏览移动Web前端的适应度函数,从而优化移动Web前端浏览性能。通过实验验证了该方法的良好优化效果。

In order to improve the fluency of mobile Web front end browsing,an optimization method for mobile Web front-end browsing performance under high concurrent access is proposed.By calculating the characteristic values of the mobile Web link in terms of CPU load,memory load,disk load and traffic flow load,a mobile Web traffic flow training sample set is constructed to judge the load status of the mobile Web front-end.According to the overload sequence and light load sequence of the mobile Web load,the status of the load balancing distribution node is obtained.Combined with the time delay status and bandwidth status of the mobile Web load balancing distribution,the mobile Web load is balanced and distributed by using bandwidth level optimization.The availability of data transmission path is calculated by using the connection relationship of communication sub-stations,the fitness function of mobile Web front-end browsing is obtained by calculating the user permission verification delay,and the browsing performance of mobile Web front-end is optimized by the security design of communication links.The good optimization effect of this method has been verified through experiments.
