基于服务分类的预测型动态负载均衡调度算法
A Dynamic Load Balancing Scheduling Algorithm Based on Service Differentiation and Prediction
摘要
Abstract
The present dynamic load balancing algorithms usually monitor load on servers,however,most of them cannot differentiate the types of the request services and the load between monitoring intervals is so difficult to achieve in real-time. Based on this situation,pres-ent a predictive dynamic load balancing algorithm PSDLB. This algorithm takes the users’ services types into consideration,as well as, the resource utilization of each server node between monitoring intervals can be predicted in real-time. On the Web Server Cluster ( WSC) of the lab,the proposed algorithm’ s two models are compared with WLC algorithm and QSC-LB algorithm in the heterogene-ous environment. The content of the comparison is the failed requests rate and the system response time of the four request service types, such as,secure transaction service,database service,small file downloading service and big file downloading service. Results of the experi-ments show that the proposed algorithm is better than the other two algorithms under high system loading condition.关键词
