Abstract: A content control system capable of controlling delivery destinations of user contents in respective groups, identifying each group through which each content is delivered, and delivering information/advertisements according to the attribution information of the content. In a content control server, group identifying information is set in each user content to be uploaded to or downloaded from a group memory area corresponding to a gateway ID from a terminal through a gateway having a plurality of its subordinate terminals. The information identifies each gateway through which each object content is delivered according to the gateway ID. The control system controls the delivery destination of each content according to the combination of the content delivery route and a table prepared in the content control server.

Abstract: A label switching type packet forwarding apparatus having a routing information table in which a forwarding type of a reception packet, output port identification information, and output routing information of a specific layer in the OSI reference model determined by the forwarding type are defined in correspondence with routing information which is found upon reception of a packet, for converting a header of a reception packet in accordance with the packet forwarding type and the output routing information obtained by a table search.

Abstract: An access node run as a packet switching apparatus enables IP connection services for a plurality of access methods; e.g., relatively low-speed IP connection, high-speed IP connection, and mobile network IP connection. By using this apparatus of the present invention, cost can be reduced and upgrading to advanced access networks and access services is easily carried out. Provision of the above access nodes implements upgrade-type network services common for diverse protocols. Each access node retains a pathfinding table to which input port, input tunnel identifier and input session identifier entries in a set are registered per session. When routing a packet, by looking up the set of these entries matching with the packet, the associated output port, output tunnel identifier, and output session identifier are obtained. After processing for the packet, appropriate for one of the plurality of access methods and network services, the node forwards the packet over the routed path.

Abstract: In a specific embodiment of the invention, a peer-to-peer interfacing device is described. The particular embodiment of the invention facilitates access by a Web browser, allowing a Web user to benefit from the access capability of a peer-to-peer network, such as file sharing. The interfacing device can communicate using a standard protocol (e.g., HTML), thus allowing the Web user to access the peer-to-peer network with a conventional Web browser. The interfacing device can interact on the peer-to-peer network side, and thus appears to the peer-to-peer network as a peer machine.

Abstract: To provide technology whereby operations for registering authentication information when connecting wireless equipment to a network via an access point can be safely conducted at the store where the wireless equipment is purchased. Member identification information identifying a user and identification information for a first access point disposed in relation to the user are stored in association with each other. The member identification information is received from a terminal installed at a store that receives wireless equipment. Subsequently, identification information for the wireless equipment is received from the wireless equipment via a second access point disposed in relation to the store.

Abstract: The selection of video content to be delivered to a video reproducing terminal is enabled from a communication terminal with WEB function without exposing a user ID. When a terminal makes a transfer request of content data, a web server requests a delivery management server for a transfer ID. The delivery management server issues the transfer ID each time the request is made and transmits it to the web server. The web server transmits the content data to a delivery server. The delivery server stores the content data from the web server correspondingly to the transfer ID. When receiving a delivery request including a transfer ID inputted to a video reproducing terminal from the video reproducing terminal, the delivery server reads the content data corresponding to the received transfer ID, and transmits it to the video reproducing terminal.

Abstract: There is disclosed an electronic advertisement system including: an advertisement displaying device; a local area network that transmits a summary of a content to a terminal; a wide area network that has at least one local area network and gains access to a detail of the content corresponding to receiving the summary by the terminal; and a center device that stores the details of the content, monitors the access to the stored detail of the content, and changes the schedule of an advertisement displayed on the advertisement displaying device located near the local area network based on the monitored result.

Abstract: Disclosed embodiments of the present invention include a peer-to-peer network comprising management server and a notification server. Information of interest can be subscribed to by peer clients. The notification server can then notify subscribing peer clients of modified information. A pure peer-to-peer architecture is also disclosed.

Abstract: Upon initialization, a VPC is set up between edge nodes. A control processor of each node creates an IP address/VPC mapping table using IP routing information and an address mapping table mapping correspondence between IP addresses and ATM addresses and supplied by a network management system. A gateway assigns a VCC to each packet input to the network. A sending-side edge node inputs the packet to the VPC corresponding to its destination by referring to the IP address/VPC mapping table. A transit node performs packet switching over VP. A receiving-side edge node transfers each packet to the gateway corresponding to its destination. If a series of packets meet a predetermined condition in a given edge node, its control processor sends VCC information to input interfaces of the edge node so that the packets are switched by an ATM switch in the edge node without intervention of the control processor.

Abstract: A scheme and a device for managing a user state and a plurality of terminal states on a presence server, and for automatically selecting an optimum terminal by using both the user state and the terminal states. Priority degrees which depend on the terminal states are set, then selecting a terminal whose priority degree is the highest of the plurality of terminals. In association therewith, a priority rank which is set depending on the user state is also taken into consideration, thereby selecting a final optimum terminal. The present scheme makes it possible to automatically perform a fine-grained selection of the optimum terminal in which both the terminal states and the user state are taken into consideration.

Abstract: This invention provides a network management equipment and a packet switching equipment which eliminate a connection setup delay time, reduce a delay and a delay variation involved in data transfer, and effectively perform connectionless data flow processing in a large data network. The network is divided into a connection-oriented core network and a plurality of connectionless access networks connected to the core network where a plurality of connections (called permanent virtual route (PVR)) are set up among a plurality of edge nodes. The network management equipment selects one route from a plurality of PVRs for connectionless data flow received from one of the access networks and transfers data along the PVR.
