摘要
结合VOD系统的实际动态负载需求,针对中心服务器,可以从动态负载均衡方向分析如何根据Android客户端的影片点击量,采取有效的调度方案来对用户请求、中心的资源进行调度管理,设计访问基于大数据存储的云分支嵌入式服务器的调度策略。使用iftop软件分析监控网卡的实时流量,通过大量Android终端同时访问多台嵌入式服务器统计超过与未超过阈值的连接数,经分析可得出该调度策略大大降低了中心服务器的负载,从而有效提高了整个VOD系统的资源利用率、用户请求相应成功率以及系统响应速度。
Combining with the actual dynamic load demand of the VOD system,for central server, from the direction of dynamic load balancing, starting from the actual demand of VOD, analyzes how to take effective scheduling scheme to resource scheduling management of user requests for the center resource with Android client movie＇s hits and design for scheduling policy accessing to cloud branch embedded server based on big data storage. Using iftop software analysis flow of real-time monitoring network card, through a lot of Android terminal access to embedded server at the same time and statistics the number of connections if or not exceed the threshold value,thus effectively improving the system resource utilization and user requests corresponding success rate and the system response speed.
