<p><P>PROBLEM TO BE SOLVED: To provide digital contents which can be efficiently distributed when a mobile terminal registered to a network sends a request for distribution to a different proxy node. <P>SOLUTION: In an overlay multicast system 10, a proxy node (specified proxy node) 21 to which a mobile terminal 11a is connected informs proxy nodes 22 to 25 that the mobile terminal 11a itself is a rendezvous point by using a retrieval result obtained by using a decentralized hash table when the mobile terminal 11a having a digital content distributes the digital contents to mobile terminals 12a to 15b. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
