ABSTRACT:
A network switching system comprises a managing device and a first switching device comprising first and second ports. The first port communicates with the managing device. A queue communicates with the second port, stores frames for later output by the second port, and generates a congestion signal when filled above a threshold. A control module directs frames received from the second port to the first port, and selectively sends an outgoing flow control message to the first port when the congestion signal is present.
