Abstract: A system and method for managing network communication in an asymmetric network environment. The system includes a gateway. The gateway receives a plurality of packets for transmission over first communication network. The plurality of packets are received via primary network path. The gateway dynamically evaluates the plurality of packets. The gateway classifies the plurality of packets into a latency sensitive packet and a latency agnostic packet. The gateway determines network capacity of the primary network path and a secondary network path. The gateway splits the latency sensitive packet and the latency agnostic packet between the primary network path and the secondary network path. The gateway selects the primary network path for transmitting the latency sensitive packet. The gateway selects the secondary network path for transmitting the latency agnostic packet over downstream transmission.
