<p>PROBLEM TO BE SOLVED: To make representatives relay communication between groups with each other and to improve economicity by deciding a repeater belonging to a second group connected through a third line as the representative device of the second group and informing it in the case of becoming the representative device for representing a first group and relaying a communication packet to the second group. SOLUTION: A relay system is constituted of these repeaters 11-13 and 21-23 and they are respectively connected by a first line 1, a second line 2 and the third line 3. The repeaters 11-13 belonging to the first group 100 are connected to the first line 1 and the repeaters 21-23 belonging to the second group 200 are connected to the second line 2. To the first line 1 and the second line 2, network devices are respectively connected. The third line 3 connects the repeater belonging to the first group 100 and the repeater belonging to the second groups 200 and the repeaters relay the communication between the network devices.</p> |
