Traffic Shaping for Hybrid Satellite/Terrestrial Wide Area Networks

A system and method for traffic shaping of a hybrid network using Internet Protocol (IP) including a first transport and a second transport, the method including: establishing an on-course line to monitor usage of the first transport over a usage cycle, wherein the on-course line defines a usage-limit of the first transport for a given instant within the usage cycle; tracking a current usage of the first transport over the usage cycle; determining a preference between the first transport and the second transport based on a property of a traffic to be transported by the hybrid network; and adjusting the preference to shift the traffic to the second transport as a distance of the current usage from the on-course line decreases for a current instant, wherein the first transport has a lower latency than a latency of the second transport.
