[导读]一直以来，DCN为实践中国SDN积累经验，致力于和业界同仁、科研学术机构和标准化组织合作，积极开发研究SDN技术。2011年，DCN与清华大学合作建设了国内最早的SDN试验床 2006年，SDN诞生于美国GENI项目资助的斯坦福大学Clean Slate课题，斯坦福大学Nick McKeown ...

很多做网络的同仁在初次了解SDN(Software Defined Networking)的架构后都会产生一系列的疑问：1)SDN真正的客户需求在哪里，它到底能解决什么问题?2)集中控制和集中网管的本质区别是什么?3)它是不是和软交换差不多?这些疑问也不无道理，简单地将控制和转发分离之后 ...

SDN诞生于美国GENI项目资助的斯坦福大学Clean Slate课题，斯坦福大学Nick McKeown教授为首的研究团队提出了Openflow的概念用于校园网络的试验创新，后续基于Openflow给网络带来可编程的特性，SDN的概念应运而生。 2006年，SDN诞生于美国GENI项目资助的斯坦福大学Clean Slate ...

SDN控制器就像是一个整个架构的中间件。控制器必须整合网络中所有物理和虚拟设备。控制器会从与设备一起工作的SDN软件中提取物理网络设备。控制器与网络设备之间高度融合。在OpenFlow环境中，控制器会使用OpenFlow协议和NETCONF协议与交换机联系。(OpenFlow是将 ...

* OpenFlow enables Ethernet network controllers to determine the path of network packets across a network of switches via software (SDN), not hardware. It is a standard supported by major switch ...

Over the past couple of years, software-defined networking (SDN) has emerged as a strong alternative to traditional networking approaches in the areas of WAN, data center networks, and network overlay ...

The future of networking will be defined by software. That was the overriding theme after the first day of the inaugural Open Networking Summit, a conference dedicated to software-defined networking ...

Brocade this week announced broad support for OpenFlow 1.3 across its IP product line to extend SDNs beyond research and academia and into commercial and enterprise networks. Brocade’s new 2x100G ...

Are We Now In The Post-OpenFlow SDN Wave? It feels like that even OpenFlow could play a role in SDN (as also OpenDaylight seems to support it) when either more custom ASICs (likely) or more scalable ...

At Interop this week, Cisco is unveiling an alternative to OpenFlow for software-defined networking and proposing it as a standard, while adding it as a vital component of the company’s new ...
