Abstract: This paper studies the flow control technology in Ethernet switch to the problem of frames losing. The flow control technology to Ethernet switch is applied. In the design, the flow control mechanism based on the data buffer is realized and the data buffer in reason is distributed. Thus the frame losing which results from buffer can be resolved.

Key words: MAC, flow control, pause frame
