2 is a conceptual diagram illustrating an operation of a connection device according to an embodiment of the present invention.

In FIG. 2, the rack 200, the first network switch 220, the second network switch 240, the connection device 250, the first communication terminal 260, the second communication terminal 270, and the third communication Terminal 280 is shown.

The connection device 250 according to the embodiment of FIG. 2 includes 20 ports. For convenience, the ports located in the A row 1 column and the ports A1 and C located in the C row 3 column are referred to as port C3.

Referring to FIG. 2, unlike FIG. 1, the first network P1 of the first network switch 220 and the second port P1 of the second network switch 240 are directly connected to each other. The first port P1 of the switch 220 is connected to the port A1, and the second port P1 of the second network switch 240 is connected to the port D1. The port A1 and the port D1 are connected to each other through a wire connection w1 in the connection device 250. Thus, these connections have the same effect as the cable connection 170 of FIG. 1. The wiring connection operation inside the connection device 250 will be described later with reference to FIG. 3.

Referring to FIG. 2, unlike FIG. 1, the first network P2 of the first network switch 220 and the second port P2 of the second network switch 240 are directly connected to each other. The first port P2 of the switch 220 is connected to the port A2, and the second port P2 of the second network switch 240 is connected to the port D2. The port A2 and the port D2 are connected to each other through a wire connection w2 inside the connection device 250. Thus, these connections have the same effect as the cable connection 172 of FIG. As shown in FIG. 1, when the cable connection corresponding to the reference numeral 172 is changed to the cable connection corresponding to the reference numeral 174, according to the embodiment of FIG. 2, the network manager requests a corresponding wire connection request from the connection device 250 ( For example, the control command to change the connection of A2 and D2 to the connection of A2 and D4) is performed, and in response, the connection device 250 changes the wire connection w2 to the wire connection w3. Therefore, according to the present embodiment, when the network manager wants to change the connection between the network switches for reasons such as reconfiguration of the network connection, the connection can be softly changed without detaching or attaching the cable. In addition, as will be described later, according to another specific embodiment, the network manager transmits the wire connection request through a remotely located communication terminal (eg, a computer, a mobile phone, etc.), and the connection device 250 receives the above-described information. Perform the wiring connection change.

To this end, according to the present embodiment, when the user of the first communication terminal 260 makes a corresponding wiring connection request (for example, a control command to change the connection of C5 and D5 to the connection of C5 and A5), the user connects in response. Device 250 changes wiring connection w6 to wiring connection w7. From now on, the user of the first communication terminal 260 can receive 100 Mbps Ethernet service. That is, unlike FIG. 1, a user of the first communication terminal 260 may be provided with 100 Mbps Ethernet service in 10 Mbps Ethernet service without a cable detachment / installation process. If the request is sent remotely, the connection can be changed remotely.
