摘要
随着信息技术和网络技术的不断发展,网际互连协议(InternetProtocol,IP)网络中的访问量和需求量正在快速增加,对传统的IP网络中的波分复用和频分复用技术提出了新的挑战。文章从软件定义网络(SoftwareDefined Network,SDN)的基本概念出发,分析了SDN的现有架构,阐述了IP网络中SDN技术的优势和发展方向。从SDN流量控制、SDN接入控制和SDN访问控制3个方面分析了SDN控制技术的实际应用,探讨了SDN控制技术对IP网络的贡献,降低了网络信息交换的复杂度,对动态控制和分配流量提出了新思路,切实高效地提升了网络资源的利用率,实现了对IP网络的智能化管控。
With the continuous development of information technology and network technology, the traffic volume and demand in the Internet Protocol(IP) network are being rapidly increasing, which poses new challenges for the wave division multiplexing in the traditional IP network for frequency division multiplexing technology. Starting from the basic concept of Software Defined Network(SDN), this paper analyzes the existing architecture of SDN, and expounds the technical advantages and development direction of SDN technology in IP network. From SDN traffic control, SDN access control and SDN access control three aspects analyzes the practical application of SDN control technology, discusses the contribution of SDN control technology for IP network, reduce the complexity of network information exchange, for dynamic control and traffic distribution put forward new ideas, effectively improve the utilization of network resources,implements the intelligent control of IP network.
