| 摘 要： | 提出了一个动态自适应的加权负载均衡运算机制.它以离散型均匀分布的原理为基础,通过各服务器向均衡器发送不同速率的请求流来实现集群节点负载的动态负反馈.仿真测试结果显示该算法优于静态算法,与动态算法相比,也减轻了前端负载均衡器的负担.

| Abstract: | To reduce the possibility of balancer becomes performance bottleneck in cluster,a dynamic adaptive weighted load-balanced computing mechanism is presented in this paper.In this mechanism,each server sends the ask stream at different rates to balancer based on the principle of discrete uniform distribution to achieve the dynamic negative feedback on workload.Simulation test results show that the algorithm is better than static algorithm.Compared with the dynamic algorithm,it can also reduce the burden on loa... |
