<p><P>PROBLEM TO BE SOLVED: To provide a frame multiplexing device having a function of fairly using the output bands of a frame multiplexing device among a plurality of lines, in which the number of storage lines is increased, and an output speed is increased without generating the increase of costs or the large-scaling of the device. <P>SOLUTION: This frame multiplexing device 100 is provided with counters 30a and 30b for each of a plurality of lines. A flow rate monitoring part 10 monitors the frame flow rate of each line based on the value of the counter corresponding to each line, and adds the frame length of the passing frame to the value of the corresponding counter. A band management part 20 cyclically selects one line from among the lines to which the frames are input, and subtracts predetermined token quantity from the value of the counter corresponding to the selected line. An output control part 40 stores the frame passing through the flow rate monitoring part 10 in a queue buffer, and outputs it as the output band of the frame multiplexing device 100. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
