摘 要:软件定义网络(software-defined networking,简称SDN)作为一种最新网络构造,对网络设备控制面、转发面和应用层功能进行重新定义抽象,使得网络设备软件可编程,为研发网络新应用和未来互联网技术提供了一种新的解决方案.基于此背景,OpenFlow技术SDN逻辑控制和数据转发分离的结构,并介绍了其相关键部件的研究进展,包含OpenFlow交换机、控制器和SDN技术。探究了SDN技术的网络管理自动化和网络虚拟化。剖析了基于OpenFlow的SDN 技术的应用以及当今面对的问题和未来研究趋势。关键词:OpenFlow;控制器;自动化;SDN8127
OpenFlow-based SDN Technology research
Abstract:Software Defined Network (software-defined networking, referred SDN) as a new network structure, network device control plane, forwarding plane and application layer functions redefined abstraction, making the network programmable device software for new applications and future R & D network Internet technology provides a new solution based on this background, OpenFlow technology SDN logical separation of control and data forwarding architecture, and describes the research progress of its associated key components, including OpenFlow switches, controllers and SDN technologies. Explores the SDN network management automation technology and network virtualization. Analyzes based on the application and the problems faced by today's SDN OpenFlow technology and future research trends.
Key words:OpenFlow; controller; Automation; SDN
