Frame transmission system

摘要

A frame transmission system includes a frame transmitter and a frame receiver. The frame transmitter includes a frame fragmentation unit and a reproduction header appending unit. The frame fragmentation unit fragments an input frame and outputs transfer frames when the length of the input frame exceeds a predetermined fragmentation reference frame length, and does not fragment the input frame and outputs 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. The reproduction header appending unit appends a reproduction header to the transfer frames outputted from the frame fragmentation unit. Here, the reproduction header being required when the transfer frames are reproduced at a receiving side. The reproduction header appending unit varies the header length of the reproduction header to be appended to the transfer frame, according to the length of the input frame.

1. 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; andappend 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.
