Abstract：With the development of network technology, the hospital network system tends to be complex, which raises a series of
problems, such as the management difficulty of hospital network, low safely, update complexity and so on. Software defined network
(SDN) improved the flexibility 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, first of all, the SDN system, including
the basic system and key components of SDN, was briefly 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.
