Abstract:
1. An end-to-end virtual private networking system for transporting network packets securely through a public data network, comprising: a mobile device comprising an application client and a wireless roaming client managing data transfer from said mobile device to said public data network via one of a plurality of predetermined wireless links; a roaming gateway located in a data center and coupled to said public data network for tracking said plurality of predetermined wireless links and for managing data transfer from said public data network to said mobile device via one of said plurality of predetermined wireless links, wherein said wireless roaming client and said roaming gateway create a first VPN tunnel therebetween; an enterprise server in a private network for exchanging network packets with said application client in said mobile device; a CPE-VPN router in said private network coupled to said enterprise server and to said public data network; a VPN router located in said data center connected to said roaming gateway and to said public data network, wherein said VPN router and said CPE-VPN router establish a second VPN tunnel therebetween via said public data network; wherein said CPE-VPN router transports said network packets between said enterprise server and said second VPN tunnel, and wherein said VPN router transports said network packets between said roaming gateway and said second VPN tunnel; and wherein the connection between said VPN router and said roaming gateway provides a secure bridge between said first and second VPN tunnels within said data center.
