Abstract:
PURPOSE: A device for configuring a virtual private network is provided to allocates private internal address. CONSTITUTION: A mobility support unit(210) generates a first conversion packet through a processing of a mobility tunnel about the packet. A data security unit(220) inspects security about the first conversion packet. A virtual address conversion unit(230) converts an HOW of the connection node into a internal address on the private network. The virtual address conversion unit generates a second conversion packet.

PURPOSE: A method for providing direct communication in an IP(Internet Protocol) network is provided to enable the direction communication between P2N(Peer-to-Network), P2P(Peer-to-Peer) or an N2N(Network-to-Network) in an IP network. CONSTITUTION: A peer node(P1) requests its own virtual address to a server(100), and the server receives a virtual address request message. The server receives a virtual address request message, and searches the virtual address corresponding to the ID of the peer node(S306). The server includes the searched virtual address in the virtual address response message for the virtual address request message. The server transfers the virtual address response message to the peer node, and the peer node sets up the virtual address included in the virtual address response message to the tunnel interface(S310).

PURPOSE: A method and a device for controlling birds using a mobile robot are provided to prevent a collision between birds and an aircraft by exterminating the birds using a remote or free control mode. CONSTITUTION: A method for controlling birds using a mobile robot is as follows. Information about surrounding situations detected by a mobile robot is input. Birds are detected from the surrounding situation information(800). Bird control patterns, corresponding to the surrounding situation information, are extracted(810). A bird control task is allotted to the mobile robot(820). Processing information about the bird control task is received from the mobile robot and is analyzed(830).
Abstract:
PURPOSE: A multi image compression apparatus and a method thereof for compressing an image inputted from a camera are provided to accurately monitor network resource in order to support a data ratio compression mode. CONSTITUTION: A video input unit(301) acquires an image which a client desires to watch the image inputted from a camera and transfers the image to an image compression unit(402). An image compressing system(405) is embedded in a plurality of compressors. A controller(309) decides whether each compressor compresses the image in a JPEG2000 mode. A network interface unit(307) receives the compression mode information from a client.

본 발명은 다중 로봇을 원격제어하기 위한 휴대 인터넷의 상향 링크 자원 할당 시스템 및 그 방법에 관한 것으로, 로봇의 역할에 따라 로봇에서 원격통제센터로 전송하는 영상의 요구품질이 서로 다르고 영상 데이터의 인코딩 특성상 전송하는 영상 데이터 크기도 가변적이며, 각각의 로봇은 무선 통신 특성상 서로 다른 통신 채널 품질을 갖고 있으며 이에 따라 변조방식과 코딩 방법이 수시로 변경되어 통신 대역폭의 변화가 자주 발생되는 상황에서, 각 로봇 역할의 중요도에 따른 영상품질과 각 로봇의 통신 채널의 품질을 고려하여 효율적인 WiBro 시스템의 상향링크 자원할당이 가능하게 할 수 있다. 로봇, WiBro, 상향 링크, 스케쥴링
Abstract:
PURPOSE: An apparatus of collecting and processing communication sensitivity is provided to perform self-control driving or monitoring of a robot by storing wireless communication sensitivity data according to location corresponding to GPS receiving coordinates. CONSTITUTION: A Wibro(Wireless broadband) base station(105) receives wireless communication sensitivity data according to location GPS(Global Positioning System) receiving coordinates. A remote control unit(106) performs path planning or channel coding using GPS information according to location and the wireless communication sensitivity data. An application(206) requests communication sensitivity a remote unmanned robot of a data receiving unit(202) according to location to a data processing unit(205). The data processing unit transmits pre-stored sensitivity data about the coordinates of the robot.
Abstract:
PURPOSE: A closed user network configuration method and a closed user network system using IP tunnel technology are provided to configure a specific purpose of network for limited user only. CONSTITUTION: A control server(10) sets the TEED(Tunnel Endpoint Edge Device)(21~27) and a control tunnel. The control server forwards the TEED and a transmitted and received packet by using closed IP section information assigned to the TEED. The TEED sets the control server and a control tunnel. The TEED assigns a closed IP within the close IP interval assigned from the control server to terminals(31~36) connected to the TEED. The TEED comprises a NAT(Network Address Translation) function.
Abstract:
PURPOSE: A high speed IP flow mediation apparatus using a network processor is provided to process and mediate IP flow information generated and transferred from an internet high speed circuit to lossless. CONSTITUTION: A server(210) collects flow information about an IP traffic of a high-speed circuit. A network processor board(220) of a NIC form based on a PCI is mounted on the server. The network processor board analyzes the collected flow information. The network processor board transfers the analyzed information to plural flow analysis systems. A flow transmitting unit(214) transfers the collected flow information from the network processor to the board.
Abstract:
A method and system for supporting Internet protocol (IP) mobility independently of the IP version of a transport network are provided. The method includes providing a mobility control apparatus, which maps the home addresses of a plurality of mobile terminals, including first and second mobile terminals, and the Care-of-Addresses (CoAs) of the mobile terminals, and setting a first control tunnel between the mobility control apparatus and the first mobile terminal, the care-of-addresses varying from one transport network to another transport network; setting a second control tunnel between the mobility control apparatus and the second mobile terminal; and enabling the first and second mobile terminals to exchange a data packet with each other through the first and second control tunnels.
