  • Publication number: 20130301654
    Abstract: A reception IF receives a frame from a transmission source. A transmission IF outputs the frame received from the transmission source. A frame counting unit counts a frame having a size not more than a predetermined value, out of the frames output from the transmission IF, for each transmission source. When a transmission source from which a predetermined number of frames having a size not more than the predetermined value are continuously counted is present, a fragment control unit fragments a frame having a size larger than the predetermined value from other transmission source than the transmission source, and outputs the fragmented frame from the output IF.
