<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and method with a distribution type data storage processing configuration for efficiently executing processing of acquiring and reproducing data from each node. <P>SOLUTION: A reproduction instruction apparatus for transmitting a data reproduction processing request to a node connected to a network is configured to revise and set a reply probabilityβto be applied to the decision processing for deciding whether or not the node receiving the reproduction processing request packet executes the processing in compliance with the processing request depending on a packet transmission sequence and to control the transmission timing of the reproduction processing request packet. The apparatus sets a higher reply probabilityβfor an initial data request, executes the processing of setting a lower reply probabilityβto prevent reception of wasteful packets when a buffer free capacity is decreased and also adjusts the packet transmission interval. Thereby, the efficient utilization of the buffer and high speed reception are realized. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
