Abstract:
An apparatus and a method for monitoring a mobile Internet protocol network are provided to monitor conveniently and effectively a mobile Internet protocol network by managing correlation between nodes of the network, a current connection relation and a protocol operation state of the network. A configuration management unit of a mobile Internet protocol network registers a target node desired to be monitored and establishes a connection with the registered target node(S302). A packet transmitting/receiving unit receives a packet including management object information from the target node and transfers it to a packet translation unit(S304). The packet translation unit analyzes the received packet and transfers the management object information to a node management unit. The node management unit stores the received management object information in a management information base(S306). The packet transmitting/receiving unit receives a packet including packet transmission/reception history information from the target node and transfers it to the packet translation unit(S308). The packet translation unit analyzes the received packet and transfers the packet transmission/reception history information to the node management unit. The node management unit transfers the packet transmission/reception history information to a display unit so as to be outputted to a user screen(S310). The packet transmitting/receiving unit receives a packet including management object information from the target node and transfers it to the packet translation unit(S312). The packet translation unit analyzes the received packet and transfers the management object information to the node management unit. The node management unit stores the management object information in the management information base(S314). When the user requests the management object information, the node management unit displays the management object information on the user screen through the display unit(S316).

본 발명은 Mobile IPv6를 지원하는 망에서 실시간 서비스 제공을 위한 빠른 핸드오버 구현 시, 이동 단말에서의 빠른 핸드오버 기능을 구현하지 않고도 네트워크 측에서만 빠른 핸드오버 기능을 구현함으로써 빠른 핸드오버를 지원을 가능케 하는 방법 및 시스템에 관한 것이다. 이를 위해 이동 단말이 현재 위치한 라우터에서 데이터 링크 계층 핸드오버 신호를 수신하면, 이동 단말이 이동하려는 라우터로 핸드오버의 시작을 표시하는 메세지를 송신하고, 이동 단말이 이동하려는 라우터가 이동 단말이 현재 위치한 라우터로 핸드오버의 시작을 표시하는 메세지를 수신하였음을 알리는 메시지를 송신하며, 이동 단말이 이동하려는 라우터가 데이터 링크 계층에서 이동 단말에 대한 링크가 형성되었음을 표시하는 링크 업 트리거 신호를 수신하면 이동 단말로 라우터 광고 메시지 및 포워딩 된 패킷을 전송한다. 빠른 핸드오버, Mobile IPv6
Abstract:
A method and a system for supporting IPv6 neighbor discovery in a point-to-point oriented broadband wireless access network are provided to use an IPv6 neighbor discovery message without difficulty when an IPv6 network is configured by common network prefix information, thereby removing the necessity of modification of existing IPv6 neighbor discovery. A method for supporting IPv6 neighbor discovery in a point-to-point oriented broadband wireless access network comprises the followings steps of: enabling an access router(AR) of the broadband wireless access network to receive a message from a terminal existing within the broadband wireless access network(5); enabling the access router(AR) to detect whether the received message is a neighbor discovery message or not; and enabling the access router(AR) to relay the detected neighbor discovery message to terminals(SS1,SS2) existing within the broadband wireless access network(8).
Abstract:
Disclosed are a network node apparatus for information-centric networking and a method of operating the same. The network node apparatus according to an embodiment of the present invention has a separated network control plane and a data transfer plane, and manages location information of content on the data transfer plane in a centrally concentrated form. For example, the network node apparatus includes a content service coordination function (CSCF) for processing a content request from a user or an issue request from a content provider, a content delivery control function (CDCF) for selecting an optimum service node which will process the content request or the issue request, and a content delivery service function (CDSF) for providing the user with the requested content or downloading the content whose issue has been requested from the content provider to register the content.
Abstract:
The present invention relates to a system and a method for delivering content by combining a transparent internet cache server and a content delivery network and, more particularly, to a system and a method for delivering content which can overcome the capacity limit of a cache storage of a transparent internet cache service and the limit of service transparency of a content delivery network service. According to the system and the method of the present invention, a transparent internet cache server and a content delivery network are combined to overcome the capacity limit of the cache storage of the existing transparent internet cache service and the limit of the service transparency of the content delivery network.
