摘要
智慧园区云计算场景要求多租户环境下的业务安全部署和快速变更,传统网络较难适应。软件定义网络(Software Defined Network,SDN)具有转控分离、可编程接口开放、控制集中化、业务自动化应用等特点,可满足园区网络极简融合、集成管理、统一运维、策略随行、弹性拓展和业务灵活等需求。笔者在阐述智慧园区建设需求的基础上,探讨SDN Overlay技术的作用以及在智慧园区建设中的适用性,提出基于虚拟可扩展局域网(Virtual eXtensible Local Area Network,VXLAN)的智慧园区SDN网络架构方案,设计智慧园区网络整体架构和拓扑结构,并对SRv6+SDN、5G+AIoT等新技术在智慧园区中的未来应用作出展望。
The scenarios of smart campus cloud computing require secure deployment and quick response to changes in a multitenant environment, therefor a traditional network is difficult to adapt to. The SDN has the characteristics of separation in transferring and controlling, programmable interface, centralized controlling, and automation in business application. With these characteristics,the SDN network is capable in agile integration, integrated management, unified operation and maintenance, policy accompanying,flexible expansion and business flexibility of a campus network. On the basis of expounding the needs of smart campus construction,the role of SDN Overlay technology and its applicability in the construction of smart campuses are discussed, and a VXLAN-based smart campus SDN network architecture solution is proposed. The overall architecture and topology of the smart campus network are designed, and the future application of some new technologies such as SRv6+SDN and 5G+AIoT technology in smart campus construction is prospected.
