Abstract:

Nowadays, the control and management of computer networks becomes more and more complex,and we put forward more and more requirements on high-end routers,which is the key device in networks. There are so many problems we should take into account when we design a new network router architecture. These  problems include the opening, extensibility, scalability and flexibility, security and safety,and users＇choice of routers. This paper presents a survey y of the new network architecture of high-end routers. It discusses new network  twork controlling, software scalable router architecture and user-oriented network control.

Key words: high-end router, router architecture;active networking
