Title:
CONTENT DISTRIBUTION SYSTEM, NODE, CONTENT DISTRIBUTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2010/125791
Kind Code:
A1
Abstract:
Disclosed is a content distribution system wherein a logical network for each content is configured using user devices and an update information distribution server as nodes. If one of the user devices has come to be unable to exist in the logical network, a connection invitation message is transmitted from one of the nodes to one or more other user devices. When the other user devices receive the connection invitation message, each of the other user devices transmits the connection invitation message with a delay according to the distribution efficiency of the logical network of the user device. The node having transmitted the connection invitation message connects to the logical network the user device which has first transmitted the received connection application message in place of the user device which has come to be unable to exist in the logical network.
