An article distribution system is provided that can find threads that are active for articles among the users of a community. A user terminal for receiving the contribution of articles that are viewed among users is connected by way of a communication network to an article distribution device for registering articles and appraisal data in an article database. The article distribution device is provided with an article distribution unit, an article registration unit for performing registration, and an article appraisal unit. The article distribution unit receives article distribution requests from the user terminal and transmits article registration data that are relevant to the user terminal. The article registration unit displays article registration data that have been transmitted by the article distribution unit and receives the input of articles that contain cited portions to register these article registration data in the article database. Based on the articles that have been registered in the article registration unit, the article appraisal unit calculates appraisal values that include the article volume, the citation volume, and the citation ratio for each article and each thread and registers these appraisal data in the article database.

Article distribution system and article distribution method used in this system

In a data packet transfer network in which a communication data is transmitted by dividing the communication data to a plurality of data packets, each of a plurality of packet transfer nodes included in the data packet transfer network comprises at least a data packet comparison circuit for comparing sequential numbers of received data packets with sequential numbers of data packets received in the past and a data packet copy circuit for copying the data packets in the order of the sequential numbers thereof and transferring the data packets to a next packet transfer node in the order of the sequential numbers. Data loss is reduced even when there is a time delay until the data is received by a destination node, so that the data is transmitted reliably.

Data packet transfer network and data packet transfer method

A routing processing system in a packet transmission is capable of restricting a delay in a routing process based on particular applications being utilized. The packet transmission routing processing system performs a routing process for an input packet and includes parsing and timer processing for identifying an application corresponding to an intended transmission of an input packet and monitoring a timer value provided for the application. Routing and transferring processes determine a transmission destination port on the basis of a destination address stored in a routing table, and dispose of the packet or transfer packet to a preliminary determined route depending on the identified application when routing process exceeds the timer

Routing processing method in packet transmission and system therefor

A network address assigning system includes sub-networks connected to each other, a network composed of the sub-networks connected to each other, an address server for managing network addresses of the sub-net-works, nodes for transmitting and receiving messages over the sub-networks, routing nodes for transmitting and receiving messages, for transferring messages over the sub-networks, and for managing addresses of the sub-networks, a change indicator for causing the address server to re-assign network addresses of the sub-networks and for causing the routing nodes to notify the address server of the network addresses of the routing nodes, storage for causing the address server to store address information, and a notifier for causing the address server to communicate with the routing nodes and to notify the routing nodes of network address information that has been newly registered/changed.

Network address assigning system

A speech information communication system includes a speech recognizer which converts an input speech signal to character code information and speech feature information. The character code information and the speech feature information are transmitted to a receiving side where the received character code information is converted to an output speech signal depending on the received speech feature information.

Speech information communication system

A communication quality control system for deciding an optimum communication quality in a received datagram to transfer the datagram, in which not only a destination is decided according to the data of the protocol layer and beneath included in the datagram, but also attribute information of communication is taken out by an attribute detecting unit, according to the information of the respective protocol layers , and or one of them, and communication quality for sending the datagram is decided by a communication quality deciding unit and a connection communication quality control unit, according to the quality information of connection corresponding to the attribute information taken out.
