摘要：
A network device that transfers frames by repeating, in a constant cycle, a reserved transfer interval that is a time band, in which a frame is transferred with a reservation, and a free transfer interval that is a time band, in which a frame is freely transferred, includes: a BPDU generation unit that generates a first BPDU; and a BPDU transmission instruction unit that instructs to arrange the first BPDU in the reserved transfer interval and transmit the first BPDU to a first other network device.
