PURPOSE: A network duplex system and method are provided to improve a system performance by simultaneously operating two processor boards. CONSTITUTION: Each processor board judges whether alarm is set to '1'(S150). If the alarm is set to '1', each processor board judges whether the other processor board has a failure(S160). If no failure has occurred in the other processor board, each processor board selectively receives only a data with an address assigned to itself and processes it(S170). If there is a problem in the other processor board, that is, for example, if processor board A is normal while processor board B has a problem, the processor board A processes the data in the address A, and at the same time, receives processing information from the processor board B to continuously process it in an address B(S180). |
