随着信息化的普及发展,电力行业的数据网也正在发生着翻天覆地的变化,其网络更为复杂、数据流量更大,包括虚拟化和新的应用服务体系结构,传统的网络体系结构已经难以适应新的需求,落后的网络体系结构阻碍了电力企业的发展。软件定义网络(SDN)是一种新型的网络体系结构,它的设计理念是网络控制平面和数据转发平面分离,并实施控制程序。我们从设备模型进行深入研究SDN的技术内涵,同时,实际需求和存在的问题的电力数据通信网,最后,讨论了软件定义网络在电力中的应用。
With the popularization of information technology, the power industry’s data network is also undergoing earth-shaking changes. Its network is more complicated and its data traffic is larger, including virtualization and new application service architecture. The traditional network architecture has been difficult Adapt to new demands, the backward network architecture hindered the development of power enterprises. Software Defined Network (SDN) is a new type of network architecture that is designed to separate the network control plane from the data forwarding plane and implement control procedures. From the equipment model, we conduct an in-depth study on the technical connotation of SDN, as well as the actual demand and existing problems of power data communication network. Finally, we discuss the application of software-defined network in power generation.
