Abstract
A data synchronization system transfers data between multiple data synchronization servers connected to a network path. The data synchronization server calculates a transfer delay on a network path involved in the transfer of data of multiple applications in an application server to another data synchronization server, predicts a time at which the transfer delay will exceed the requested delay of each application, and controls the transmission rate of data for each application so that times, at which the transfer delays will exceed the requested delays of all applications, become the same. In this way, the data synchronization system controls the data synchronization of applications between remotely installed distributed data centers so that the requested delay of each application is satisfied as much as possible.
