摘要
设计并实现新型动态负载均衡系统。该系统在Linux服务器集群系统的基础上进行扩展,完善了B/S管理界面,能监控应用级服务,有4层高可用性保证。设计专门的算法,通过历史信息预测负载以达到动态负载均衡,提高了曙光4000A服务器集群的吞吐量和利用率。
This paper describes the design and implementation of a Dynamic Load Balancing system（DLB）. Based on Linux Virtual Server（LVS）, DLB has a comprehensive B/S GUI. DLB can monitor application service and has a 4-layer mechanism of high availability assurance. With special algorithm, DLB can predict future load by analyzing history information to do dynamic load balance, so the throughput and utilization rate of Dawning-4000A duster are increased.
