Abstract: Provided are methods of ensuring network continuity performed at a local gateway, a fixed gateway, and a network device. The method of ensuring network continuity performed at a local gateway includes establishing a tunnel with a fixed gateway serving as a relay between an Internet service server and the local gateway, and performing communication with the fixed gateway through the tunnel. Therefore, even when the type of an uplink signal received by a local gateway changes or the local gateway is in an uplink signal shadow area, a terminal connected to the local gateway can be provided with a seamless Internet service.

Abstract: A method and an apparatus of integrative network management, which provide connection between private networks and real-time connection according to various policies depending on security or a quality of service (QoS), manages information required to provide the connection, and controls connection by using the managed information in order to defend and cope with various types of cyber attacks and fundamentally invalidate a cyber attack.

Abstract: Disclosed are a system for managing virtual private networks (VPNs) includes: terminals configured to transmit user data; a manager configured to transmit information for concealing networks and managing the VPNs; border gateways configured to decrypt the user data and perform a network address translation (NAT) procedure and a filtering procedure on the decrypted user data based on the information; and servers configured to receive the user data subjected to the NAT procedure and the filtering procedure, wherein the filtering procedure is a procedure discarding the user data to be transferred to the servers that are not allowed so as to allow the terminals to access only the allowed servers, the NAT procedure is a procedure changing an Internet protocol (IP) address used in a first network to an IP address used in a second network, and the first network and the second network are different networks.

Abstract: To conduct video conferencing between a plurality of distributed clients, a distributed controller receives a request from a first distributed client for a packet from a second distributed client selected as the main speaker, and a distributed media processor creates a switching entry for switching packets from the first and second distributed clients, in response to a request from the distributed controller. The distributed controller sends a packet transmission request to the second distributed client, and the distributed media processor receives a packet from the second distributed client and sends the received packet to the first distributed client based on the switching entry.

Abstract: A system for providing a video conference service is provided. The system includes a Multipoint Processor (MP) configured to process media occurring during a video conference so as to allow the processed media to be transmitted/received between user terminals; and one or more Multipoint Controller (MC) configured to control a session of a user terminal participating in a multi-participant video conference, wherein the MP and the MC are separate from each other.

Abstract: The invention relates to a method and an apparatus for controlling seamless handover between heterogeneous networks based on IPv6 over IPv4 tunneling. When IPv6 service is provided using tunneling in an IPv4 based network environment, handover of a mobile terminal between different networks is achieved through switching of an active tunnel and a standby tunnel, and thus handover between different networks is facilitated and data loss is prevented to secure continuity of service provided to the mobile terminal even when the mobile terminal hands over to a heterogeneous network.

Abstract: In order to select a conference processing device to host a video conference between conference participation devices, a video conference system selects conference processing devices that are positioned most adjacent to each of conference participation devices that participate in the video conference as candidates for a conference processing device. The video conference system forms network topology based on candidate conference processing devices and conference participation devices, and aligns candidate conference processing devices based on preset alignment reference information. The video conference system selects one of the aligned candidate conference processing devices as an optimal conference processing device to host the video conference.

Abstract: The present invention relates to tunneling an IPv6 packet through an IPIv4 network. In using a tunneling method upon transmitting an IPv6 packet in an IP network, when destination nodes desired to be communicated are located within the same IPv6 prefix network, IPv6 prefix information is added for the management of a tunnel entry. Hence, tunneling information on terminals located within the same IPv6 prefix network can be managed as one tunnel entry. Accordingly, the time consumed when retrieving a tunnel entry can be reduced.
