A switch device includes: a first relay circuit deciding a transmission port to which the frame of the first communication is output, when the received frame is the first communication; a processor deciding a transmission port corresponding to a destination address of the received frame, and generating a second relay table including information for identifying the transmission port corresponding to the destination address of the received frame; and a second relay circuit deciding a transmission port to which the frame of the second communication is output, as the transmission port to which the frame of the second communication is output, a transmission port corresponding to the destination address of the received frame among the plurality of ports on the basis of the content of the second relay table, when the port that has received the frame of the second communication is an end port. |

1. A switch device including a plurality of ports, the switch device comprising:
a determination circuit configured to determine whether a received frame is either a first communication or a second communication; a first relay circuit configured to decide a transmission port to which the frame of the first communication is output, among the plurality of ports, on the basis of content of a first relay table when the determination circuit determines that the received frame is the first communication; a processor configured to decide a transmission port corresponding to a destination address of the received frame among the plurality of ports, and to decide an upstream port corresponding to each of an end port and a downstream port among the plurality of ports, and to generate a second relay table including information for identifying the transmission port corresponding to the destination address of the received frame, and information for identifying the upstream port corresponding to the end port or the downstream port; and a second relay circuit configured to decide, as a transmission port to which the frame of the second communication is output, the upstream port corresponding to the end port or the downstream port among the plurality of ports on the basis of the content of the second relay table when the port that has received the frame of the second communication is the end port or the downstream port, or to decide, as the transmission port to which the frame of the second communication is output, a transmission port corresponding to the destination address of the received frame among the plurality of ports on the basis of the content of the second relay table when the port that has received the frame of the second communication is neither the end port nor the downstream port, in the case where the received frame is the frame of the second communication. |
