PROBLEM TO BE SOLVED: To utilize a duplexed network connector for improving a performance by distributing a load at the time of normal operation and to maintain usability without interposing any software of a host computer in the case of fault. SOLUTION: At the time of reception processing, respective network connectors 150 and 151 are connected to a network switch 180 to receive the same reception data. The reception data to be transferred to a host are selected based on contents of the data, so that the reception data can not be missed and overlapped as a whole. In this case, when any fault occurs, the reception data to be selected by the remaining network connector are dynamically changed so as not to lose a reception function as a whole.
