There is provided port switches SWP1 to SWP4, fabric switches SWF1 and SWF2, and user switches SWU1 and SWU2, the port switches SWP1, SWP2 functioning logically as one switch by being connected with a shared communication line between redundancy ports Pr. The port switch SWP2 may receive frames from the user switch SWU1, and when the frames are to be originally transferred from a port P1 to the fabric switch SWF1, the frames are transferred though the redundancy port Pr to the port switch SWP1 if there is a fault on the port P1 side. The port switch SWP1 transfers the frames received from the port switch SWP2 through the redundancy port Pr to the fabric switch SWF1 that is the original transfer destination. |

1. A communication system, comprising:
a first port switch, a second port switch, and a third port switch; a first fabric switch and a second fabric switch; and a user switch, wherein the first and second port switches each comprise a redundancy port, wherein the redundancy port of the first port switch and the redundancy port of the second port switch are connected by a shared communication line, wherein the user switch is connected to each of the first and second port switches through different second communication lines, and ports of the user switch that are connection sources of the second communication lines are configured for link aggregation, wherein the first port switch, the second port switch, and the third port switch are each connected to the first and second fabric switches through different first communication lines, and ports of each of the first port switch, the second port switch, and the third port switch that are connection sources of the first communication lines are configured for link aggregation, wherein the ports of the first and second fabric switches, which are the connection sources of the first communication lines connected to the first and second port switches, are configured for link aggregation, wherein, when there is no fault, the second port switch transfers actual data signals received from the user switch through the second communication line to the third port switch through the first communication line between the second port switch and the first fabric switch, and when there is a fault in the first communication line between the second-port switch and the first fabric switch and there is not a fault in the first communication line between the second port switch and the second fabric switch, the second port switch transfers the actual data signals to the first port switch through the shared communication line and does not transfer the actual data signals to the second fabric switch through the first communication line between the second port switch and the second fabric switch, and wherein the first port switch transfers the actual data signals received through the shared communication line to the third port switch through the first communication line between the first port switch and the first fabric switch. |
