<P>PROBLEM TO BE SOLVED: To reduce the amount of data stored on a network to prevent delay of content delivery to a client from being prolonged. <P>SOLUTION: A data distribution system includes a plurality of nodes and distributes data to a client terminal. Each node included in a node group that forms a distribution route to the client terminal comprises: a storage part for storing at least one block satisfying a predetermined condition corresponding to a cost required to reach the client terminal among a group of blocks that are generated by dividing a piece of distribution data, which is data for delivery to the client terminal, into multiple pieces in the chronological order of execution; and a segment transmission part for transmitting the at least one block stored in the storage part when a distribution request for the distribution data is made from the client. <P>COPYRIGHT: (C)2012,JPO&INPIT |
