SDN的架构包含三个不同的层:应用层、AO810 3BSE008522R1控制层和基础设施层[3]。

最顶层是SDN环境中的应用层，它包含各种程序，这些程序提供通信并检查应用编程接口使用的行为和其他资源[4]。SDN的控制器是中间层，它从不同的设备获取数据，并与SDN应用程序进行通信。基础架构层负责数据平面。

AO810 3BSE008522R1此外，它接受来自控制器的指令，并进一步转发数据进行解析。SDN技术在SDN发现后发展迅速，各种新兴技术如SD-WAN [5]、SD-Storage、第五代等都有了显著的提升。此外，它还与云计算、网络安全等其他技术相集成[6]。

随着集中化成为网络行业的新常态，思科等公司也开始在网络设计的几乎每个部分使用这种方法，无论是企业广域网、园区网络、无线、安全，我们都看到SDN或其他软件定义的技术快速加速网络，帮助组织实现自动化、更快的部署、零接触供应、应用感知、服务链、单一窗口门户等优势。

The architecture of SDN consists of three different layers: the application layer, the AO810 3BSE008522R1 control layer and the infrastructure layer [3].

The top layer is the application layer in the SDN environment, which contains various programs that provide communication and check the behavior and other resources used by the application programming interface [4]. The controller of SDN is the middle layer, which gets data from different devices and communicates with the SDN application. The infrastructure layer is responsible for the data plane.

AO810 3BSE008522R1 In addition, it accepts instructions from the controller and further forwards the data for parsing. SDN technology has developed rapidly after the discovery of SDN, and various emerging technologies such as SD-WAN [5], SD-Storage, and the fifth generation have been significantly improved. In addition, it integrates with other technologies such as cloud computing and network security [6].

As centralization becomes the new normal in the networking industry, companies like Cisco are also starting to use this approach in almost every part of network design, whether it's enterprise wide area networks, campus networks, wireless, security, and we're seeing SDN or other software-defined technologies rapidly accelerate networks. Help organizations realize the benefits of automation, faster deployment, zero-touch provisioning, application awareness, service chains, single-window portals, and more.
