inly the following experiments: singlearm routing, static routing and access control lists, corresponding to the subway network or campus network, the pany’s routing backup and server filter. They are such practical problems that we have a deep impression on these experiments up to now.In addition, the teacher also told us some interesting things that our students are very concerned about, such as the PPPOE connection of campus tele broadband, the cause of the wireless router which is invalid in school, wireless’s way of encryption and how to decode and so on. He mainly introduced some experiences when he was engaged in this industry, the present situation of network industry and he also forecasted the future market.
