Abstract：This paper analyses the present situation and existing problems of computer network training teaching in technical colleges. It points out that the importance of building network training room based on virtual simulation technology. Firstly，the paper introduces virtual simulation technology，and then describes its advantages in computer teaching. Taking Cisco Packet Trace as an example，it discusses how to use the virtual simulation software to carry out small bureau. The networking and testing work of LAN proves the feasibility of virtual simulation technology in computer network training teaching. At the same time，it points out the existing problems of using virtual simulation technology in computer network teaching，and tries to give solutions. Finally，the paper summarizes the points and aspects，and points out that we should not only see the innovation brought by virtual simulation technology to computer network teaching，but also recognize the challenges it brings to us. In this paper，virtual simulation technology is introduced into computer teaching.
