The Reseach And Implementation Of The Campus Network Multi-export Strategy

All along with the progress of times, human being has stepped into the network information era and the network has becoming the foundation of life and work.All of these office activities such as real-time conversation,handling official business,cooperation and so on and entertainment events can not do with network,which means the network has been the centre of human being's life and work in the new age.As one of public services of universities, The campus network reconstruction is a long-term foundation engineering.To construct a campus network as a collection of voice, video and data which achieves a high standard, being safe,high-powered and reliable ,we should make full use of all kinds of advanced network technology, which aims at providing services for the school's teaching, scientific research, offering facilitating conditions such as resource sharing,academic exchange and video conference for school, improving the efficiency of higher institution running with cost reduction, providing a solid base for making a digital campus.Taking UPC for example,this article will discuss how to make use of thousand trillion ethernet(part of the backbone nodes can use 10Gb ethernet technology)to transform the campus network into a multifunctional and advanced network system collecting digital DS(digital speech),VI(video image) and high data rate transmission.In the future, the campus will provide wired or wireless network interconnected function(NIF) for all kinds of communication equipment such as telephone,PDA,laptop and so on. Meanwhile, it will offer instant and efficient networking feature for students dormitory and teacherage, which makes it convenience for teachers and students to acquire latest information resource rapidly and fosters the capability of autonomic learning of students.This article will discuss how to use the technology such as Policy Route, routing policy, NAT, GRE Tunnel, achieve the technology of Tethering for students,teachers,lads and public school computer rooms, promote the awareness of getting online safely.
