DATA SYNCHRONIZING METHOD, DATA SYNCHRONIZING SYSTEM, AND DATA SYNCHRONIZING PROGRAM

摘要

PROBLEM TO BE SOLVED: To synchronize outputs of each data flow at each reception terminal when each reception terminal receives a different data flow respectively and to eliminate a load of synchronization processing from each reception terminal.

SOLUTION: In a first method, each packet included in a plurality of data flows is transmitted in order of a generated time. A synchronous node adjusts a transmission interval of each packet to be the same as a generating interval of each packet. In a second method, a receiver side synchronous node plays a different role from that of a transmitter side synchronous node. The receiver side synchronous node receives a plurality of data flows and composes packets included in each data flow and whose generated time is the same into one packet. The composed packet is transmitted to the transmitter side synchronous node, wherein the composed packet is decomposed and restored to the original data flow. The transmitter side synchronous node transmits the restored data flows to respective transmission destinations. Thus, the load of synchronous processing can be eliminated from the reception terminals for receiving the plurality of data flows. When each of the plurality of reception terminals receives different data flows, outputs from the reception terminals can be synchronized without the need for synchronization processing at reception terminal sides.
