摘要
软件定义广域网是将软件定义网络技术应用于广域网,以实现高效、特色连接服务的技术。研究分析政府、企业新型云化业务部署快速发展后,针对网络传输承载的需求,结合软件定义网络和网络功能虚拟化等技术的发展,提出了一种较为精简的、内生安全的软件定义广域网网络架构,并给出了其典型的应用场景。该网络架构主要包括软件定义安全接入路由器、虚拟化安全路由器、动态编排与智能控制设备等关键设备,并给出了实现上述关键设备的初步原理框架,具有较好的可实现性。
Software-Defined Wide Area Network is a technology that applies the Software Defined Network technology to achieve efficient and characteristic connection services.After researching and analyzing the rapid development of the deployment of new cloud services by governments and enterprises,in response to the needs of network transmission and bearer,combined with the development of Software Defined Network and Network Function Virtual technologies,a relatively streamlined,endogenous and secure Software-Defined Wide Area Network architecture is proposed,and its typical application scenarios are given.The network architecture mainly includes key devices such as security software defined secure access router,virtualized secure router,dynamic arrangement and intelligent control equipment,and gives a preliminary principle framework for realizing the above-mentioned key equipment,which has good feasibility.
