ABSTRACT:
A network device that controls the communication of data frames between stations receives data frames from a number of stations. The network device detects a congestion condition associated with processing the received data frames and generates a pause frame including source address information relating to the source of the congestion. The network device transmits the pause frame to a second network device. The second network device identifies the source address included in the pause frame and suspends transmission of data frames with that source address to the network device. The second network device may also transmit the pause frame including the source address to a third network device.
