【Abstract】 In this paper, the net bottleneck problems that are caused by net routing have to depend on traditional router after local net are divided are analyzed firstly.Then, the latest 3-layer packet-switch technology is studied in detail from three aspects: its basic principle and topology, its principle chart of its implementation of hardware and software and its feature. At last, its application in various networks and its development in the future are discussed briefly.更多还原
