什么是SDN ?
SDN
Software-Defined Networking
ONF： SDN is a new approach to networking and its key attributes include: separation of data and control planes; a uniform vendor agnostic interface between control and data planes; a logically centralized control plane; and slicing and virtualization of the underlying network・
Gartner： Software-defined networking (SDN) is a new approach to designing； building and operating networks that focuses on delivering business agility while lowering capital and operational costs. It is far more than just a new set of APIs designed to replace command line interfaces for managing individual devices・
开放API
Overlay
Google: As networking systems scale, whether it be growth in bandwidth or the number of users being served, one has to worry about manageability, cost-efficiency, robustness and availability of the network fabric. SDN allows you do tackle many of these problems.
控制面与数
VMware: VMware Software Defined Networking (SDN), available today, helps solve the data center networking challenge, which virtualizes the network and creates logical networks that meet the agility, performance and scale requirements of virtualized applicationsand data・
Verizon： Verizon has deployed SDN as an overlay network for video distribution services・ For scale and flexibility, the SDN framework must support multiple VM domains, multiple network domains, and multiple services/applications with open, standard interfaces： |
