Abstract
An approach is provided whereby multiple broadband connections operate together to provide a highly available secure private networking solution. Data packets of a communications flow are received by a networking device, for transmission to a remote destination node, over a wide area data communications network. A service classification is determined for the data flow. A sequence number is generated for each data packet, where the sequence numbers indicate an order by which the data packets are received. An indication of the service classification and the sequence number is added to each data packet. For each data packet, a transport policy is determined that indicates one or more VPN tunnels through which the data packet is to be transmitted, where the determination of the VPN tunnels is based on the service classification, and wherein each VPN tunnel is carried over a respective WAN transport of the wide area data network.
