软件定义网络的发展及其在医院网络中的应用

Development and Application of Software Defined Network in Hospital Network

随着网络技术的发展,医院的网络系统也趋于复杂,主要存在管理困难、安全性低、更新复杂等问题。软件定义网络(Software Defined Network,SDN)通过使数据平面和控制平面分离,提高了网络的灵活性和扩展性,把SDN应用到医院网络中能很好的解决医院网络的问题。因此,本文首先对SDN体系进行了简单的介绍,包括SDN的基本体系与关键组件。其次,结合国内外的研究进展,本文综述了SDN在医院网络中的应用现状,并总结了医院网络现存的问题以及解决办法。最后,本文对未来SDN在医院中的应用做出了展望。

With the development of network technology, the hospital network system tends to be complex, which raises a series of problems, such as the management diffculty of hospital network, low safely, update complexity and so on. Software defned network （SDN） improved the ？exibility and extensibility of the network by making the data plane and control plane separation. The problems of network can be solved well as SDN is applied to hospital network. In the present study, frst of all, the SDN system, including the basic system and key components of SDN, was brie？y introduced. Secondly, based on the research progress of SDN at home and abroad, this paper stated the application status of SDN in hospital network, and summarized the existing problems and solving methods of the hospital network. Finally, this paper made an outlook on the application situation of the SDN in the future.
