基于SDN的云计算网络模型设计

A Cloud Computing Network Model Based on SDN

目前,园区网络的三级架构模型已经无法满足云计算网络发展的需求。分布式应用的数据处理需求,使数据中心网络的带宽瓶颈从南北向变成东西向,采用基于软件定义网络(Software Defined Network,SDN)的云计算网络模型可以满足当前大数据数据交换的网络需求。该模型采用Clos硬件架构,基于软件实现了SDN控制器与Neutron网络模块集成。笔者探讨基于SDN的云计算网络模型,以期为相关研究提供借鉴。

At present, the three-level architecture model of the park network can not meet the needs of the development of cloud computing network. The data processing requirements of distributed applications change the bandwidth bottleneck of the data center network from north-south to east-west. The cloud computing network model based on SDN can meet the current network requirements of big data exchange. The model adopts Clos hardware architecture and realizes the integration of SDN controller and Neutron network module based on software. The author discusses the cloud computing network model based on SDN, in order to provide reference for relevant research.
