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。

关键词: 重构, 广域网, 软件定义广域网

Abstract:

There are many problems on traditional WAN,change is imperative,and it is very important to reconstruct WAN,which leads to software defined-wide area network (SD-WAN) reconstructing style.Among the current technology,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.

Key words: reconstruct, WAN, SD-WAN
