| 摘 要： | 该文从区分服务和负载均衡两方面研究Web集群系统,设计并实现了一种支持区分服务的负载均衡集群模型,通过系统辨识和资源最优控制,对后端资源统一调度,动态调整每台后端节点不同优先级业务类的资源配额;同时设计了基于业务类的最大空闲节点优先的负载均衡策略以保证各个后端节点同一业务类资源被公平消耗,从而控制端到端延迟,实现比例延...

| Abstract: | From the view of differentiated service and load balancing,this paper proposes and implements a load balancing cluster architecture supported differentiated service.By system identification and resource optimal control,the front-end dispatcher can adjust the resource quotas assigned to different classes in every single back-end server,and Multi-class based Maximum Idle First(MIF) load balancing strategy is designed to ensure every class a fair consumption among back-end nodes.As a result,the end-to-end dela... |
