摘要
随着SDN技术的快速发展以及开源SDN控制器的日益成熟,SDN相关技术的标准化进展迅速。各标准组织为SDN定义了南北向接口,在SDN接口标准化方面,控制器与底层网络的南向接口以OpenFlow为代表,通过控制器向上层业务应用开放的北向接口,其标准化工作正在逐步展开。SDN北向接口的发展目前主要包括几条主线,一条是以开源系统为代表的实践中的北向接口发展路线,一条是由各个标准组织推动的北向接口标准化发展路线,同时,学术界对SDN北向接口的开放也有自身的考虑,本文综述了这几个方向的发展现状及趋势。
Willi the rapid development of SDN lechiiology and the increasing maturity of SDN open source controllers,the standardization of SDN is making process.Various standards organizations defined southbound and northbound interfaces of SDN,in the SDN standardization of interfaces,there is no effective standard on northbound as OpenFlow on southbound interface.There are many achievements on the research of SDN northbound interface.The development of northbound interface includes some clues,one is open source system,the other is standardization,and acadeniia to open SDN northbound interfaces has its own considerations,the development status and trends of these directions were reviewed.
