数字化校园网络架构优化与实现策略研究

The optimization and implementation strategy of digital campus networks

网络架构优化及其各节点的实现策略是数字化校园建设的关键技术,通过对数字化校园网络的链路均衡技术和负载均衡技术的研究,给出了具有高稳定性、高可伸缩性的网络架构,同时给出了架构中外部接入的互联及链路均衡策略、内部应用服务的二级负载均衡策略,Windows Server 2003环境下各策略的测试结果表明,该网络架构在多个策略的支持下有效地实现了稳定的互联及链路均衡、高可伸缩性及高效负载均衡的目标,有效地增强了服务器性能的适应性,降低了数字化校园建设的硬件投入成本。

The optimization and implementation strategy of every node is the key technology for digital campus network architecture. The network architecture with high stability and scalability is given on the basis of the investigation on link balancing and load balancing technology. The external internet access, the link balancing strategy and the two-stage balancing strategy of internal application services are also provided. In Windows Server 2003 the results of each strategy measurement show that the objectives of stable interconnection, link balance, high scalability and high load balance of this network architecture are implemented effectively due to these several strategies. The adaptability of server performance is greatly improved. The costs of the digital campus construction hardware are reduced.
