Research of Virtual Enterprise with MPLS VPN

摘要

The Virtual Enterprise (VE) is based on MPLS VPN (Multi-Protocol Label Switching Virtual Private Network), which can improve the performance of the routers effectively, enhance the scalability of the network layer, safeguard the Quality of Service and provide more fallibility in the routing function. Nowadays, the virtual enterprise makes use of not only language, word and symbol, but graphics, image, animation and video information. In the past, the private line is the right choice, but, it is expensive. With the increasing users and all kinds of applications, it is the desired method to add up the private line. In this condition, price and service are the first two matters. It is a severe challenge for the Internet providers to advance high-efficiency and steady-going Internet service on the basis of available Internet information. It is proved that the VPN is the alternative. For the reason of bandwidth and security existing in virtual enterprise, the paper will apply MPLS VPN to realize the perfect virtual enterprise.
