  • Publication number: 20130166775
    Abstract: Provided are a load balancing apparatus, which is configured to prevent an overload from occurring and perform effectively a load balancing operation even for servers distributed throughout a network, and a load balancing method performed using the same. the method may include determining whether a data packet received from a client may be a packet requiring a load balancing operation, determining at least one of physical servers provided in a distributed server farm as an target server to provide a service to the client, depending on the judgment, determining a forwarding path between the client and the target server, determining a header rewriting node, and referring the forwarding path and the header rewriting node to determine a forwarding rule and load the forwarding rule on a switch provided on the forwarding path.

  • Publication number: 20110270985
    Abstract: An open access node receives a dynamic IP address corresponding to a terminal that requests a connection from a specific server, and provides the dynamic IP address to the terminal. Next, the open access node receives a service that is requested by a user from the terminal that is connected using the dynamic IP address, and stores a MAC address of the terminal and a service in a database. When the terminal again requests a connection, the open access node identifies a service that is requested by a user of the terminal based on the MAC address of the terminal.

  • Publication number: 20110255545
    Abstract: A virtual local area network (LAN) control system for controlling at least one virtual LAN through a network accessed by a plurality of terminals includes a terminal, a virtual LAN switch, and a virtual LAN controller. The terminal has a proper identifier address to access the network, or receives a proper identifier address through an external device connected to the virtual LAN switch. The virtual LAN switch sets and provides at least one virtual LAN through the network. When the terminal accesses the virtual LAN controller to request to change the configuration of the virtual LAN, the virtual LAN controller assigns authority to change the virtual LAN to the terminal so as to change from the virtual LAN to which the terminal belongs to another virtual LAN.

  • Publication number: 20110131630
    Abstract: A service access method and device, a user authentication device, and a terminal are provided. A service access method includes requesting a terminal to transmit authentication information in response to a service access request that is received from the terminal, receiving the authentication information from the terminal, permitting a temporary access to the terminal based on a result of a temporary authentication performed based on the authentication information, and processing a main authentication based on the authentication information.
