| 摘要 |
The present invention provides a network connection method which prevents connection by virus-infected communication devices or communication devices intended for unauthorized access to a network, and enables connection to the network in a simple manner. A user of a requestor communication device connects to a main network by inserting a cable of the communication device to a port of a network device. When the requestor communication device is connected one-on-one to a reception box by a check-in network inside the network device, check-in is performed using the reception box. When the reception box determines through check-in processing that the requestor communication device satisfies connection qualifications, the reception box switches the network, to which the requestor communication device will be connected, from the check-in network to the main network. The requestor communication device then makes a transition to actual use of the main network. |

1. A communication system, comprising:
a main network that provides various services, a check-in-network for qualification screening/setting provided independently from the main network, a reception control section connected to the main network and the check-in-network, a plurality of ports including at least ports a through h, a communication device, and each port c-h is configured to connect the communication device to the main network and to port b via the check-in-network on a one-on-one basis, the reception control section being connected to the main network via port a, and the reception control section controls switching of the connect of the communication device to the main network from port b, a hub that is incapable of mutually connecting communication devices respectively connected to ports c to h, and a device comprising at least one processor and memory storing a computer program, the at least one processor executing instructions of the program to perform: quarantine connection of the communication device on a one-on-one basis to the reception control section via the check-in-network when the communication device requests connection to the main network; qualification screening, provided at the reception control section, that acquires status information of the quarantine-connected communication device on a one-on-one basis to determine whether the status satisfies preset qualification requirements; and connecting the check-in-network, that the communication device is connected to, to the main network upon determination that the qualification requirements are satisfied, wherein the qualification screening/setting is executed in a VLAN or a VPN at a layer lower than a network layer of an Open System Interconnect model upon status change of a link. |
