发明名称 INFORMATION DISTRIBUTION SYSTEM AND METHOD, AND COMMUNICATION DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide an information distribution system capable of selecting a communication path via which information can be transmitted from a server to a user most efficiently to improve the utilization efficiency of communication network resources. <P>SOLUTION: A plurality of time distribution servers perform time distribution to a packet relay network to establish time synchronization in a communication network. A communication device that received time information from the plurality of time distribution servers acquires a time from the time distribution server at the shortest temporal distance from the device, and registers the connection with the server as a preference communication path to apply the path to distribution for information other than the time information. <P>COPYRIGHT: (C)2013,JPO&INPIT
