Method and system for preventing congestion of communication signals in a gateway device

A system includes a first communication system, a second communication system and a network processor in communication with the first communication system and the second communication system. The first communication system and the network processor communicate first network signals therebetween. The first network signals include first higher priority network signals and first lower priority network signals. The second communication system and the network processor communicate second network signals therebetween. The second network signals include second higher priority network signals and second lower priority network signals. The network processor communicates a first congestion notification request signal to the first communication system. The first communication system throttles or shapes the first lower priority network signals at the first communication system in response to the first congestion notification signal to form first modified network signals and communicates the first modified network signals to a first user device.
