Abstract:
An authentication switch monitors a failure of an external server, and redirect information to a Web server that holds authentication information registration screen data is provided to a terminal using a monitoring result. A life-and-death monitoring control unit for monitoring life and death of an external Web server is disposed within an authentication switch to monitor the life and death of the external Web server. An authentication processing unit within the authentication switch switches the redirect information on the basis of a life-and-death monitoring table of the external Web server provided in the life-and-death monitoring control unit in response to an authentication request from the terminal, and enables web authentication even when the external Web server is in failure.
Abstract:
A relay device connected to a node and connects the node to a network, wherein, when receiving an address acquisition request through a physical port, the relay device transmits, to the node, an address acquisition reply including an address to be set in the node, node information identifying the node that has transmitted the address acquisition request, and an address of the setting information storage device which is connected to the network and configured to store setting information of the node, transmits, to the setting information storage device, a setting information acquisition request which is transmitted with an address of the setting information storage device set as a destination and which includes the node information, and transmits, to the node, setting information which corresponds to the node information included in the setting information acquisition request and which is transmitted from the setting information storage device.
Abstract:
A virtual tunnel endpoint that makes a communication of a specific tenant is separated from virtual tunnel endpoints that make communications of the other tenants. A forwarding route from the virtual tunnel endpoint that makes a communication of the specific tenant is separated from a forwarding route from the virtual tunnel endpoints that make communications of the other tenants. Accordingly, a communication of the specific tenant is forwarded with priority.
Abstract:
A communication apparatus including: a plurality of physical ports to be coupled to different terminals via a network; a plurality of authentication processing units configured to execute an authentication process; and a controller configured to determine which one of the physical ports on which a packet was received from a terminal, to specify a preset authentication process corresponding to the determined physical port on which a packet was received, and to distribute the specified authentication process of the packet from the terminal to an authentication processing unit for executing.
Abstract:
It is provided an authentication method for realizing a network authentication function for an authentication system, the authentication system including an authentication server for authenticating a terminal used by a user, and a switch for mediating an authentication sequence between the terminal and the authentication server. The authentication method includes steps of: providing, by the switch, identification information for identifying the switch to the authentication server in the authentication sequence; authenticating, by the authentication server, an authentication request transmitted from the terminal; transmitting, by the authentication server, an authentication result of the authentication to the switch based on the provided identification information on the switch; and authenticating, by the switch, access from the terminal based on the authentication result received from the authentication server.
