摘要
为了缩短网络地理信息系统(WebGIS)所有并发用户的响应时间,解决并发访问时产生的响应滞后问题,提出一种基于任务响应比优先调度的WebGIS动态负载均衡算法,该算法提升了目前WebGIS负载均衡算法并发处理能力,均衡了并发访问情况下所有用户响应时间。通过仿真实验,证实该算法与具有代表性的传统负载均衡算法相比,能有效缩短所有用户并发请求的平均响应时间,提升服务器的并发处理能力。
In order to reduce all of the concurrent user response time and solve the response lag in WebGIS,a WebGIS dynamic load balancing algorithm based on response ratio priority scheduling is proposed.The algorithm enhance the concurrent processing capabilities of load balancing algorithms in current WebGIS,balance all of the concurrent user response time.Simulation results show that,compared with the traditional load balancing algorithms,the algorithm proposed in this paper can effectively reduce the average response time of all concurrent requests and enhance concurrent processing capabilities of the map servers.
