Abstract:
본 발명은 특수 목적의 메모리를 사용하지 않고 일반적인 메모리를 사용하면서 해시 방법을 이용하여 정책 기반 라우팅을 효율적으로 수행하기 위한 방법을 제공한다. 정책 기반 라우팅 테이블은 기본 테이블 및 확장 테이블을 포함한다. 기본 테이블 및 확장 테이블은 각각 복수 개의 단위 엔트리를 포함한다. 단위 엔트리는 해시 값 별 IPv6 검색 정보, 출력 포트 정보 및 확장 테이블의 엔트리를 지시하는 확장 포인터를 포함한다. 패킷이 입력되면, 기본 테이블에서 입력된 패킷에 대한 단위 엔트리가 검색된다. 입력된 패킷에 대한 단위 엔트리가 기본 테이블에서 검색되지 않으면, 확장 테이블에서 입력된 패킷에 대한 단위 엔트리가 검색된다.
Abstract:
The present invention relates to a system and a method for managing harmful traffic filtering information. More specifically, if an edge router of a second autonomous system (AS), which is positioned at the rear end, detects harmful traffic and sets up traffic filtering information, the edge router transmits the traffic filtering information to a first AS at the front end, from which the harmful traffic was transmitted, through a border gateway protocol (BGP), and then the corresponding first AS applies the received traffic filtering information to a related router. Therefore, harmful traffic can be blocked in advance at the front end from which the harmful traffic is transmitted.

Abstract:
PURPOSE: A system and a method for operating a network based on network virtualization are provided to obtain the scalability and flexibility of a virtual network with a virtual network discrimination method based on a network service. CONSTITUTION: A network operating device comprises an operation interface part (210), a resource management part (220), a virtual network control part (230), a virtual network configuration specification database (240), and a virtual network profile database (250). The resource management part manages network resources. The virtual network control part forms multiple virtual networks discriminated by domain names and sets a representative virtual router of each virtual network. The virtual network control part sets representative routing information including the IP address of each representative virtual router in a virtual router contained in each virtual network. The virtual network configuration specification database stores the IP address of each representative virtual router corresponding to the domain names. The virtual network profile database stores the profile of each virtual network.

Abstract:
PURPOSE: A network bandwidth distribution device and a method thereof are provided to equally distribute a network resource to all the users regardless of a connection order for each user. CONSTITUTION: An information collector collects information associated with a connection environment. A controller judges a state of the connection environment according to the collected information and collects the information for each user to judge whether an occupied bandwidth for each user is exceeded. A bandwidth allotter (130) limits an occupied bandwidth for each user based on the judged state of the connection environment, and whether or not an occupied bandwidth for each user is exceeded.

Abstract:
PURPOSE: A taxi information providing method is provided to effectively supply demand information and supply information to a consumer and a supplier of a taxi by using a terminal of a user and a terminal of the taxi. CONSTITUTION: A taxi information providing server receives taxi information of a corresponding taxi from one or more taxi terminals and receives a taxi usage request from a user terminal (220,240). The taxi information providing server transmits taxi demand information corresponding to the taxi usage request to one or more taxi terminals which transmit the taxi demand information (260). The taxi information providing server transmits taxi supply information corresponding to the taxi demand information to the user terminal (270). [Reference numerals] (210) Transmit a taxi usage request; (220) Receive the taxi usage request; (230) Transmit taxi information; (240) Receive the taxi information; (250) Select a taxi which is located in a predetermined distance from the position of a user; (260) Transmit taxi demand information; (270) Transmit taxi supply information; (AA) Start; (BB) End
