| Abstract: | A solution combining high-speed network communication and gateway pattern is presented to realize the hard consistency and integrity of distributed real-time database system in SCADA(Supervisory Control And Data Acquisition). Its implementation is introduced. A performance test is carried out with 100 Mb Ethernet and Intel 100/1000 Mb net card. The results show that the speed of receiving client information matches the updating of real-time database in SCADA. The scheme has been practiced. |
