The media plays an important role in laboratory opening management. Asymmetric information and poor communication have aggravated the contradiction between supply and demand of equipment，and affected the quality of laboratory opening and students^enthusiasm for creation. Media environment，managers and students^habit determine the choice and use of media. As a mobile office platform，Dingtalk can make the laboratory managers who do not have the capability of technology development complete the design and development of relevant applications. By the platform，a mobile open system is built to achieve totally open in laboratory contents，equipment and management， it is suitable to the changing of student U media behavior in the mobile Internet environment. The applications and practice of the platform in the Media Opening Laboratory of Chongqing University，contain to deploy related equipment booking module， lab reservation module and undergraduate innovative experiment projects submitting module. The platform can also enhance the collaboration efficiency and bring some references for other opening laboratories in the new media era. [ABSTRACT FROM AUTHOR]

The lab study for routing and switching technology generally needs the support from a certain number and different types of physical devices and networking environment，but in most cases，teachers and learners dont have the ability to buy the physical devices and to build networking environment. The paper uses Cisco Packet Tracer free software and open source project GNS3 open source software as simulator and implements to give the integrity lab solution for routing and switching technology on the background of campus network in single machine environment + it can provide the network configuration requirements of campus network and the network topology structure. The paper compares and discusses the use process of two kinds of simulator software from three aspects including routers，switches， terminal equipment，and provides the design thought and the configuration reference for otlier comprehensive lab about routing and switching technology in single machine environment [ABSTRACT FROM AUTHOR]
