<p><P>PROBLEM TO BE SOLVED: To provide a technology for achieving high-speed data insertion, retrieval, and deletion in a P2P network including a low-performance communication terminal or the like which becomes a bottleneck. <P>SOLUTION: The communication terminal configuring a P2P network forming a hierarchical structure is provided with: a performance comparing part 10 for comparing the performance of a communication terminal with the performance of the other communication terminal in a P2P network; a layer setting part 20 for setting the layer of the other communication terminal having lower performance and belonging to a layer same as or higher than the layer to which the communication terminal belongs, to the layer which is lower than that to which the communication terminal belongs; and an another terminal recognition part 30 for recognizing the other communication terminal belonging to the layer higher than that to which the communication terminal belongs and for not recognizing the other terminal which belongs to the layer lower than the layer to which the communication terminal belongs. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
