Security Protection Design and Multi-port Transport Technology in Computer Network.

Computer network has realized its popularization after years of development. For its high office efficiency, computer network is widely used by enterprises and campus. However, factors such as the operating system, viruses and Trojan horses have brought serious concealed danger to network security in the process of practical application. Combined with the present situation of computer network security, the work studied the security protection design of the network. Besides, the work also analyzed the multi-port transmission technology briefly from transmission equipment and characteristics.
