摘要
传统广域网存在诸多问题,变革势在必行,重构广域网意义重大,从而引出软件定义广域网(SD-WAN)重构方式。综合现阶段多种技术,对SD-WAN定义、架构到开放平台、控制平面协议、南向协议等方面进行分析和探讨,如何选择具体技术需要结合技术本身成熟度和应用实践来决定。
There are many problems on traditional WAN, change is imperative, and it is very important to reconstruct WAN, which leads to software defmed-wide area network （SD-WAN） reconstructing style. Among the current tech- nology, the definition of SD-WAN, SD-WAN architecture, ODL open platform, protocol of control platform and southern protocol were analyzed and discussed. How to choose specific technology needs to combine technology maturity and application practice to decide.
