<p><P>PROBLEM TO BE SOLVED: To download a file over a tranfer rate of a server, and to download the file, even if it is difficult to receive data because of access concentration to the server, by receiving a file required by a client not only from the server but also from other PC on a network which retains a copy. <P>SOLUTION: On an information network NW capable of communicating one another, data is obtained not only from a server SV but also from a client C2, which retains a copy or a part of a required file, by peer to peer communication when a client C1 requires a file to the file server SV. Thus, the file can be downloaded at a higher speed. Besides, the file can be received from the client C2 even if it is difficult to download because network load is concentrated on the server SV. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
