摘要:
A node device to participate in an overlay network formed by all or a part of a plurality of node devices, mutually connected through a communication network, including: a device information acquisition means for acquiring device information of node devices to which participation request information is to be transmitted; a reachable range setting means for setting up the participation request information, transmitted on the communication network; a participation request information transmission means for adding reachable range to the participation request information and transmitting it to each of the node devices specified by the device information acquired; a reply information receiving means for receiving reply information, transmitted from a node device, and including a transfer destination table for the overlay network; and a transfer destination table generation means for generating the own node device on the basis of the transfer destination table included in the reply information received.
摘要:
A tree type network system including an information delivery device, a plurality of node devices, and an administration, wherein the node devices are connected in a tree-like shape via a communication route while placing the information delivery device in an uppermost level and forming a plurality of hierarchy levels, and the delivery information is sequentially transferred from the node device in an upper hierarchy level to the node devices in lower hierarchy levels, wherein the administration device includes: a device for acquiring attribute information of a node device, which transmits participation request information, and determines device information on the basis of the attribute information thus acquired upon receipt of participation request information of requesting device information of node device as connection candidate, and a device for transmitting the connection end candidate information thus determined to the node device which transmits the participation request information.

摘要:
There is provided an information communication system or the like that reduces load to a node device or the like for transmitting information when information is transmitted to a plurality of node devices. In an information communication system formed by participation of a plurality of node devices, mutually connected through a communication route, a node device X determines representing node devices included in each of groups divided into a plurality of (four) groups in accordance with a predetermined rule (for example, DHT), transmits main information to node devices A, B, and C thus determined, and in a case where destination of main information received from another node device is the group the node device X belongs to, transmits the main information thus received to a node device representing a group, to which the node device X belongs.
摘要:
The present invention is to provide a node device, a shared information update processing program, a shared information update means, and an information sharing system, which can quickly and assuredly update the shared information in each of the node devices without applying an excessive load to a specific apparatus such as a server.According to the present invention, there is provided a plurality of node devices mutually connectable through a network, each of the node devices saving shared information, used in common with the nodes, and in a case where each of the node devices transmits predetermined data to the node device, being a connection counterpart, the node device describing version information indicative of a version of the shared information, saved by the own node device, including: a data receiving means; a version judgment means; and a shared information update means.
