Research and Implementation of Architecture of Cluster-based Scalable Network Services
基于集群的可伸缩网络服务体系结构研究与实现*

On the analysis of present and future network service requirements, we present the architecture of cluster-based scalable network services called Linux Virtual Server, which has three tiers of load balancer, server pool and backend storage. The load balancer supports IP load balancing and content-based request distribution techniques. The LVScluster provides load balancing, scalability and availability, which can be deployed to build many scalable network services. We give a geographi-cally distributed LVS clusters, which can save bandwidth, improve quality of network services and be disaster-tolerant.
