Abstract
VPN is one of the most potential new generation telegraphy professional works. The program based on MPLS VPN improves the disadvantage of traditional IP network. At the same time, it can provide the same security service as ATM network. So it can adapt the VPN work requirement. The MPLS VPN model is introduced, the MPLS/L2 VPN and MPLS/L3 VPN program, and analyzed the advantage and challenge of the technology.
