With the continuous strengthening of network security requirements,one-way network communication control strategy(only from the designated side of the firewall to the opposite side,otherwise it will be rejected)is more and more applied in the high security network environment.One way network communication control strategy is conducive to improve the level of network security protection,but it brings additional complexity(data secondary synchronization)and transmission delay to real-time data access and transmission.This paper designs a"relay"data file transmission software scheme based on FTP protocol,which has been successfully applied in the real-time data business system of Huafeng Meteorological Media Group Co.,Ltd.and effectively solves the problem of repeated data storage and large data delay of high-frequency real-time data transmission in the scenario of one-way network communication control.
