Todays Internet application needs grow with each passing day, the bandwidth, delay requirements are also getting higher and higher; how to improve the transmitting efficiency, each router manufacturers made a lot of improvements, such as Cisco with CEF ( CiscoExpressForwarding ) function, modify the routing table search algorithm and so on. But this does not completely solve the current serious problems the Internet is facing with . ATM and IP were two opposite to each other, but in the end the two technology integration, that is MPLS ( Multi-ProtocolLabelSwitching ) technology was born! MPLS technology combined with IP technology and ATM signaling simple exchange engine has high efficiency, can easily deal with all kinds of flexible business needs. This paper mainly introduces the MPLS VPN technology and a
