Frame transmission system

A frame transmission system comprising:

• a frame transmitter adapted to:
• fragment an input frame so as to output transfer frames when a length of the input frame exceeds a predetermined fragmentation reference frame length, and not fragment the input frame so as to output the input frame as a transfer frame when the length of the input frame is less than or equal to the fragmentation reference frame length;
• and
• append a reproduction header to the output transfer frame, the reproduction header being required when the transfer frames are reproduced at a receiving side;
• and
• a frame receiver adapted to reproduce the input frame from the transfer frames received from the frame transmitter,
• wherein the frame transmitter is adapted to vary a header length of the reproduction header to be appended to the transfer frame, according to the length of the input frame,
• wherein, when the length of the input frame is less than or equal to ½ of the fragmentation reference frame length, the frame transmitter is adapted to not append the reproduction header to the transfer frames,
• when the length of the input frame is greater than ½ of the fragmentation reference frame length and less than or equal to the fragmentation reference frame length, the frame transmitter is adapted to append a first reproduction header having a first predetermined header length to the transfer frames, and
• when the length of the input frame is greater than the fragmentation reference frame length, the frame transmitter is adapted to append a second reproduction header having a second predetermined header length, which is longer than the first predetermined header length, to the transfer frames.
