摘要
为提高内容分发网络(content delivery network,CDN)分发管道的智能分配响应速度,文章提出了一种基于CDN和软件定义网络(software defined network,SDN)相结合的相关架构。该结构是将SDN的控制与转发分离架构和CDN网络结合,将CDN网络的转发平面与控制平面分离,将控制平面集中起来,并将SDN的控制平面划分区域管理,使得数据转发时的管道更加智能和迅速,区域划分则能让用户在管理上更加清晰明了,流量管道的转发上也更加透明。最后与传统CDN-SDN架构进行对比,结果表明该文所提出的架构比以往的架构在数据转发时管道智能选择以及连接方面有了一定的优化提升。
In order to improve the intelligent distribution response speed of content delivery network(CDN) distribution pipeline, a related architecture based on the combination of CDN and software defined network(SDN) is proposed. This architecture combines the SDN control and forwarding separation architecture and the CDN network, separates the forwarding plane of the CDN network from the control plane, concentrates the control plane, and divides the SDN control plane for the regional management, thus making the pipeline faster and more intelligent in data forwarding, and allowing clearer management for users and more transparent forwarding of traffic pipeline. Compared with the traditional CDN-SDN architecture, the proposed architecture has the advantages in optimizing the intelligent selection and connection of pipeline in data forwarding.
