Dynamic use of multiple wireless network links to connect a vehicle to an SD-WAN

A non-transitory machine readable medium storing a program for execution by at least one processor of an edge router operating in a vehicle, the program dynamically distributing data message flows across a plurality of wireless network links for forwarding from a device operating in the vehicle to a software-defined wide area network (SD-WAN), the program comprising:

• determining future locations of the vehicle based on a route to be traveled by the vehicle;
• retrieving a plurality of metrics for each wireless network link in the plurality of wireless network links;
• based on the retrieved plurality of metrics, determining predicted metrics for each wireless network link at each of the future locations of the vehicle, the predicted metrics representing expected performance of the respective wireless network links at the future locations;
• based on the predicted metrics, identifying, for each of the future locations of the vehicle, candidate wireless network links to use from among the plurality of wireless network links;
• and
• when the vehicle reaches each of the future locations, forwarding the data message flows to a destination router of the SD-WAN using the candidate wireless network links identified for the respective future location.
