摘要
软件定义网络(Software defined network,SDN)将网络的控制面与转发面解耦。面向云计算的GIS服务当前的研究热点和发展方向,将SDN运用于GIS云,能有效提高服务效率和质量。针对基于云计算的GIS系统GISCloud,提出在基础网络中引入SDN,设计了四层SDN架构,实现控制面与转发面的分离;设计了面向GIS的网络负载优化方法,提高网络效率;设计了SDN对GISCloud的虚拟化支持,满足定制化的服务,从而实现SDN在面向时空信息数据中心中的应用和发展。
According to GISCloud, this paper introduced SDN into the basis network. The paper designed the four-layer SDN architecture to separate the control plane and the forwarding plane, designed a network traffic optimization approach to enhance the network efficiency, and designed the visualization support for GISCloud to meet the specialization requirements. This study could implement the application and development of SDN in GIS data center.
