Instantaneous interruption switching device, instant interruption switching method and program

摘要

To provide a method of performing non-interruptive switching of data transmission regardless of the delay relationship between transmission lines.SOLUTION: The non-interruptive switching device detects a synchronization signal included in data for each of the data received via multiple transmission lines, determines the identity of the data which has been received via each transmission line until the synchronized signal is received, calculates the delay relationship and the amount of delay between transmission lines from the synchronization signal detected for each transmission line and the result of determination of the identity, and writes the data received via the multiple transmission lines to the memory while synchronizing with each other.SELECTED DRAWING: Figure 1
