PURPOSE: A diary-based SNS(Social Network Service) providing method and a system using the same are provided to supply an SNS through tagging information, thereby forming a new social network with experts or people having common interests. CONSTITUTION: A request for using a diary-based SNS is received from a user terminal in order to make a user tag list(S210). The user tag list composed of tags obtained by the user terminal is made(S220). A social network is formed between a user and other users based on the tags of the user tag list(S230). A diary is made based on the user tag list and the social network related to the tags of the user tag list(S240).

단말 중심의 네트워크 (endpoint-oriented network) 와 컨텐트 중심의 네트워크 (Content-oriented network) 가 결합된 하이브리드 네트워크 시스템을 제안한다. 인터넷의 접속이나 웹 서핑 등과 같이 대화 중심의 네트워킹에 대해서는 단말 중심의 네트워크로 접속되고, 영화, 음악 등의 대용량의 컨텐트 데이터를 전송하는 경우에는 컨텐트 중심의 네트워크로 접속된다. 하이브리드 네트워크
Abstract:
PURPOSE: Inter-networking between an Internet protocol network and a content-centric network is provided to enable content to be requested and delivered between two heterogeneous networks through inter-networking. CONSTITUTION: A heterogeneous networks internetworking device (200) performs inter-networking between an Internet protocol network (100) and a content-centric network (110). The heterogeneous networks internetworking device comprises a proxy function unit and a packet convert unit. The proxy function unit receives a content requesting packet from a first network and determines a destination network including a node where the received packet is delivered to. If the destination network is the content-centric network, the packet convert unit converts the content requesting packet into a packet for the content-centric network. The packet convert unit delivers the converted packet to the content-centric network.

Abstract:
PURPOSE: A mobility and multicast supporting method in a content recognition network structure and system thereof are provided to change a content focused network based on an existed IP(Internet Protocol) network into a gradual content focused network through a content recognition router and a content recognition agent. CONSTITUTION: A first content recognition agent(750) communicates with a first access station(720) and other apparatuses within one or more networks. A portable terminal(710) transmits content request packets including requested content information to a first content recognition agent through the first access station. The first content recognition agent acquires the content through the network connected with other apparatuses. The first content recognition agent transmits the content to the portable terminal.
Abstract:
PURPOSE: An automated internet video journal writing method and a system using the same are provided to automatically write a real life journal without user intervention, thereby keeping a journal with abundant records. CONSTITUTION: A request to write a video journal is received(S310). User information and time information are obtained from the request(S320). A tracking list with a plurality of tracking items from location data is generated based on the user information and the time information(S330). A video list with a plurality of video items from video data is generated based on the tracking list(S350).
Abstract:
The present invention relates to a method and an apparatus for delivering contents over a named data network (NDN). According to a first aspect of the present invention, a method for delivering contents in a content delivery system configured to deliver packets from one node to another node, based on an open flow network system including multiple nodes configured to transmit and receive packets using content names, a switch device configured to relay a flow transmission/reception among the multiple nodes, and a controller device configured to control the switch device, comprises the following steps. When a packet is received, the switch device determines whether the received packet is a packet to be delivered over the NDN. And, when the received packet is the packet to be delivered over the NDN, the switch device acts as an entity of the NDN based on a type of the packet. By using the present invention, an NDN which utilizes a pre-established network is configured.
