| With the popularization of Internet technology,information system has greatly improved people's efficiency,information system plays an increasingly important role in enterprises.The popularization of the Internet also brings the problem of network security.All computers connected to the Internet are likely to suffer from network attacks.Enterprises deploy their important systems in the internal network,they strictly control the data exchange between networks to avoid disclosure of confidential information and hacker attacks.The data unidirectional transmission system designed in this paper is deployed between two networks with different dense levels,the system enables data to be unidirectional transmitted between networks.In this paper,unidirectional optical Ethernet and serial simplex are used to design and realize unidirectional transmission channel,on the both sides of the one-way transmission channel can't connect each online.This method ensures the security of the internal network and prevents the internal network from being attacked by the external network.In this paper,one-way transmission channel is researched to how to achieve the stability transmission and how to achieve maximum transmission speed.This paper analyzes the characteristics of one-way transmission,studies the application based on one-way transmission channel,how to achieve data forwarding and how to deal with large number of connections.In this paper,the design and implementation of data one-way transmission system is completed.The system includes one-way transmission channel and synchronization service based on one-way transmission channel.In this paper,the stability and reliability of the transmission channel are tested,and the transmission speed is higher than the current one-way transmission technology in some cases. |
