Claim Text:
1. A packet transmitting method using an input circuit and a plurality of relay devices coupled to the input circuit through a plurality of paths, the method comprising: receiving, by the input circuit, a first packet group including a plurality of packets, each of which has a same destination address; receiving, by the input circuit, a second packet group including a plurality of packets, each of which has a same destination address; selecting a relay device from among the plurality of relay devices based on a first rule that rules a round robin manner for each of the plurality of packets included in the first packet group, and transmitting each of the plurality of packets included in the first packet group to the selected relay device through the plurality of paths, respectively; selecting a relay device among the plurality of relay devices based on a second rule that rules the round robin manner for each of the plurality of packets included in the second packet group, and transmitting each of the plurality of packets included in the second packet group to the selected relay device through the plurality of paths, respectively; counting a difference between a first number and a second number, the first number indicating a number of packets transmitted to a first relay device included in the plurality of relay devices through a first path included in the plurality of paths, and the second number indicating a number of packets transmitted to a second relay device included in the plurality of relay devices through a second path included in the plurality of paths; when the first number is higher than the second number and the difference between the first number and the second number reaches a predetermined value, selecting the second relay device regardless of whether the first relay device is to be selected based on the first rule; and transmitting the first packet group to the second relay device through the second path.
