Abstract
The invention provides an electronic device and a flow control method thereof, wherein the electronic device can transmit a specific pause frame to another electronic device, or receive a specific pause frame from the other electronic device. The specific pause frame includes a local port flow control ability and a remote port congestion status for the electronic device to perform the most appropriate processing of each received packet, or to selectively transmit a pause frame to external devices to improve the efficiency of the network system.
Claims17
