摘要
PROBLEM TO BE SOLVED: To provide a technology for efficiently executing data synchronization processing even when a low speed communication path or an unstable communication path is used.;SOLUTION: A synchronization target data processing device comprises: a synchronization target data acquisition unit 12; an available channel monitoring unit 13 for detecting a communication path that is available with a synchronization destination device; a communication state monitoring unit 14 for selecting one communication path on the basis of transfer speed of each detected communication path, and measuring stable communication duration time in the selected communication path; a division parameter calculation unit 15 for calculating a division parameter in dividing synchronization target data, on the basis of a data amount that can be transmitted at the transfer speed within the measured stable communication duration time; a data division unit 16 for sequentially storing division data obtained by dividing the synchronization target data on the basis of the division parameter in a division data storage unit 17; and a synchronization processing unit 18 for performing synchronization processing which sequentially transfers the division data being stored to the synchronization destination device through the selected communication path, and deleting the division data whose synchronization processing has been completed from the division data storage unit 17.;COPYRIGHT: (C)2013,JPO&INPIT
