Abstract:
1. A method for data synchronization, which applies to distributed systems that comprise a transmitting (Tx) device and at least one receiving (Rx) device, the method comprising: the Tx device using one or more bulk data channels to transmit bulk data and a real-time data channel to transmit real-time data to the at least one Rx device; prior to a continuous bulk data transfer, the Tx device sending a first message through the real-time data channel to instruct the at least one Rx device to switch to the one or more bulk data channels; and after the continuous bulk data transfer, the Tx device sending a second message through the one or more bulk data channels instructing the at least one Rx device to switch to the real-time data channel, wherein the first message instructing the at least on Rx device to switch to the one or more bulk data channels carries Rx device information, the Rx device determines whether the Rx device information carried in the first message includes itself, the Rx device switches to a corresponding one of the one or more bulk data channels indicated in the Rx device information, if the Rx device determines that the first message includes itself, and the Rx device remains on the real-time data channel, if the Rx device determines that the first message does not include itself.
