| Abstract: | L2TP VPN and MPLS VPN were IP VPN technology, L2TP was a technique which forwarded layer 2 Protocol Data Units （PDUs）, especially PPP, through a data transfer tunnel established on top of public data network services, so as to provide a means for setting up layer 2 virtual leased links. MPLS technique, combined with the fast ATM and dynamic IP routing protocol, was simplified route choose of core routers, constructed wideband Intranet, Extranet, and satisfied flexible applications. It was introduced the application of L2TP VPN and MPLS VPN in VPN System of railway administration. |
