Abstract:
1. A method for controlling a relay device connected to another relay device and a plurality of terminal devices via a network, the relay device relaying a frame between the plurality of terminal devices and the other relay device, the method comprising: selecting a Media Access Control address as a first address of a terminal device, among a group of addresses containing different addresses based on a rule for selecting the first address, the first address being used between the relay device and the terminal device; sending to the terminal device pointer information for selecting the first address among the group of addresses stored in the terminal device; receiving a frame containing an address of a device that transmitted the frame; judging whether the received address included in the frame is the first address selected based on the rule; producing a converted frame by converting the received address included in the frame as received into a second Media Access Control address of the first terminal device used between the relay device and the other relay device when the received address included in the frame is the first address selected based on the rule; and transmitting the converted frame to the other relay device.
