US Patent 7613120 Dynamic wide area network packet routing

Methods, apparatuses, articles of manufacture, and systems for creating on a first router a first local route segment, notifying a second router of the first local route segment, receiving by the second router the notification, receiving by the second router a packet destined for a computing device coupled to the first router, routing the packet to its destination over a first (e.g. public) wide area network and the first local route segment, and, on “failure” to route a packet through the first network, routing the packet over a second (e.g. enterprise) wide area network connecting the first and second routers via a second local route segment, are described herein.
