Method and system for performing diagnostics in a gateway device based on monitoring parameters

A gateway device comprising:

• 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 network processor communicating a first congestion notification request signal to the first communication system;
• the network processor communicating a second congestion notification request signal to the second communication system;
• and
• the first communication system modifying first network signals, that are communicated between the first communication system and the network processor, at the first communication system in response to the first congestion notification request signal to form first modified network signals to allow coordinated control of the first modified network signals relative to the first network signals and relative to second network signals, that are communicated between the second communication system and the network processor, and to allow receipt of the first modified network signals at the network processor.

A method of controlling a gateway device comprising a network processor, a first communication system, and a second communication system, the method comprising:

• generating a first congestion notification request signal and a second congestion notification request signal at the network processor to allow coordinated control of first network signals and of second network signals, the first network signals being communicated between the network processor and the first communication system and the second network signals being communicated between the network processor and the second communication system;
• communicating the first congestion notification request signal from the network processor to the first communication system;
• communicating the second congestion notification request signal from the network processor to the second communication system;
• and
• responsive to the first congestion notification request signal, modifying the first network signals at the first communication system, the modifying forming first modified network signals to allow coordinated control of the first modified network signals relative to the first network signals and the second network signals.
