基于SD-WAN技术的企业组网研究

企业广域网组网技术,一直受到传输效率低、网络延迟大、组网成本高等问题的制约。为此,该文将软件定义网络和广域网技术结合运用,为企业广域网设计基于SD-WAN(软件定义广域网)的架构模式。在这种架构中,充分运用SD-WAN技术,通过控制器单元、CPE单元、POP单元的配置,实现企业网和公共网络的高效对接。为了进一步提高传输效率,提出一种新的加速方案。实验结果表明,在该文构建的企业广域网架构下,经过该文提出的加速方案处理,视频信息流和文本信息流的传输实时性都得到明显改善。

The enterprise wide area network networking technology has always been constrained by low transmission efficiency,high network latency,and high networking costs.Therefore,this article combines software defined network and wide area network technology to design an SD-WAN based architecture pattern for enterprise wide area networks.In this architecture,SD-WAN technology is fully utilized to achieve efficient connection between the enterprise network and the public network through the configuration of controller units,CPE units,and POP units.In order to further improve transmission efficiency,a new acceleration scheme has been proposed.The experimental results show that the real-time transmission of video information flow and text information flow has been significantly improved under the enterprise wide area network architecture built in this paper after the acceleration scheme proposed in this paper.
