1. A frame transmission method of an electronic device, comprising:
establishing a link with another electronic device to establish a plurality of virtual lanes, wherein each of the plurality of virtual lane has a corresponding priority;
receiving a pause frame from the another electronic device, wherein the pause frame comprises a plurality of inter frame gap control indicators, and each of the plurality of inter frame gap control indicators indicates a plurality of packet size ranges and corresponding pause times;
referring to the pause frame to select one of the plurality of inter frame gap control indicators according to a priority of a first packet to be sent to the another electronic device, and determining a first inter frame gap according to which packet size range a packet size of the first packet belongs to;
sending a first frame comprising the first packet to the another electronic device through one of the plurality of virtual lanes that corresponds to a same priority as the first packet; and
after the first frame is sent to the another electronic device, at least waiting for the first inter frame gap before starting to send a second frame to the another electronic device.
