面向数据中心异构SDN的网络协同编排平台设计与实现
|
摘要
软件定义网络(SDN)技术为高速发展的云计算提供了网络解决方案,而数据中心SDN的规模化部署必然带来SDN异构互通、统一管理和协同编排需求。在研究SDN异构互通、北向接口标准化和协同编排等关键技术及其发展现状的基础上,提出通过网络协同编排平台SDNHub实现跨域、跨厂商、跨SDN控制器互通和互操作的方法,并给出了平台的方案设计和系统实现,最终实验结果证明,平台具备多控制器接入和异构资源池调度能力。
The requirements of interoperability, unified management and orchestration for heterogeneous SDN data center solutions have been identified. Based on the study of heterogeneous SDN interoperability, northbound interface and orchestration technology, SDN Hub was proposed as the orchestrator to satisfy the requirements. The architecture and system design of SDN Hub was also presented. Experiment result proves SDN Hub achieves the design goal of multi-controller access and heterogeneous resource pool scheduling.
