软件定义网络

在这样的背景下，基于OpenFlow的软件定义网络（SDN）体系架构应运而生。

OpenFlow-based Software Defined Network comes into being under this background .

比如Nicira（已被VMware以12.5亿美元收购）的软件定义网络；

Think of examples like Nicira ( acquired by VMware for $ 1.25 billion ) in software-defined networking ;

软件定义网络（SDN）是一种网络方法，允许管理员通过抽象更低级功能来管理网络服务。

Software-defined networking ( SDN ) is a networking approach that allows administrators to manage network services by abstracting lower-level functionality .

举例来说，软件定义网络（SDN）比传统的网络设备成本更低且更灵活，而思科当年正是靠传统网络设备成名的。

One example ? Software-defined networking , an approach that is considered to be cheaper and more flexible than the traditional networking equipment upon which Cisco built its name .

华为已同意收购Amartus专注于软件定义网络（SDN）的软件和团队。SDN是一种电信虚拟控制技术，能够减少工程师现场操作设备的需要。

Huawei has agreed to buy the Amartus software and team that specialises in software-defined networking ( SDN ) - controlling telecoms virtually , reducing the need for engineers to physically work with the equipment .

提出的路由协议可以很容易的在绝大多数已有路由器中实现，并且兼容未来的新型软件定义的网络（softwaredefinednetworks），如OpenFlow.5.研究并实现了LTE核心网络中的一个视频缓存子系统。

This protocol is compatible to most existing routers and also supports in further software defined networks , such as OpenFlow . 5 . Implementation of a prototype caching system of LTE core network .
