【Abstract】 The net bottleneck problems caused by net routing have to depend on the traditional router after the Ethernet is divided into several sections using the VLAN technology, which is firstly introduced in this paper. Then, the third layer switch technology is studied in detail which is included with its basic principles and the structures. The realization of the practical project both in software and hardware aspects is also presented and its characters and practical values are emphasized in this article. At last, its application in the Ethernet and prospects in the future are discussed briefly.更多还原
