摘　　要：计算机网络系统是智慧医院的核心,大型智慧医院建设对网络架构的要求越来越高,人随网动的传统网络架构一般存在安装效率低、策略下发速度慢、资产台账易混乱等问题,应对医院复杂网络需求时面临着网络扩展性差、管理繁琐等诸多挑战,选择合适的网络虚拟化技术,搭建新型、高速、可靠的网络架构对促进大型智慧医院的发展起到关键作用。广州某大型三甲医院从2023年起基于软件定义网络新建分院区网络项目,从部署速度、策略配置、终端管理方面体现该架构的优势,最终实验数据表明使用软件定义网络架构可以显著提升医院网络策略下发的效率。The computer network system is the core of a smart hospital,and the requirements for network architecture in the construction of large-scale smart hospitals are becoming increasingly high.Traditional network architectures with users moving with the network generally suffer from problems such as low installation efficiency,slow policy deployment speed,and easy confusion of asset accounts.When faced with complex network requirements in hospitals,they also face challenges such as poor network scalability and cumbersome management.Selecting appropriate network virtualization technology and building a new,high-speed,and reliable network architecture play a crucial role in promoting the development of large-scale smart hospitals.Starting from 2023,a large tertiary hospital in Guangzhou has built a new branch network project based on software-defined networking,showcasing the advantages of this architecture in terms of deployment speed,policy configuration,and endpoint management.Experimental data ultimately shows that using a software-defined networking architecture can significantly improve the efficiency of policy deployment in hospital networks.
