Patent ID: 8422491

Claim:
A network comprising: a network controller operating as a WAN node comprising a controller microprocessor, a controller memory module interconnected with the controller microprocessor and a WAN network interface device forming a network interface between a WAN and the controller microprocessor; a mobile router operating as a network interface between one or more local subnets and a cellular network that includes a network gateway to the WAN, comprising a subnet controller, a subnet memory module interconnected with the subnet controller, a network interface device forming a network interface between locally reachable network devices and the subnet controller and a plurality of cellular network interface devices forming a network interface between the subnet controller and the cellular network; program steps stored and operating on the mobile router for routing subnet exit data packets to the network controller over any one of the plurality of cellular network interface devices; and, program steps stored and operating on the network controller for routing subnet exit data packets to destination IP addresses listed therein including destination IP addresses on the WAN, for receiving reply data packets responsive to the subnet exit data packets, and for routing the reply data packets to the one or more mobile subnets over any one of the plurality of cellular network interface devices.
