  • Patent number: 7292595
    Abstract: Input buffer type packet switching equipment, which can output cells to an external output line having a slower output line rate than a corresponding input line rate without having buffers in its output line sections, is provided. The input buffer type packet switching equipment provides M input line buffers that store cells inputted from M input lines temporarily in a state that one of the M input line buffers stores cells inputted from corresponding one of the M input lines, in this the M is an integer being 2 or more, an M×N crossbar type switch, which provides N output lines, for switching cells outputted from the M input line buffers based on a cross point on/off control signal, in this N is an integer being 2 or more.
