Abstract: With the gradual expansion of enterprise scale and the rapid development of networks and enterprise information technology, large and medium-sized enterprises have successively established many business systems, and higher demands have been placed on the security of data synchronization between systems. For this demand, this paper designs and implements the data sharing module between unreliable communication links based on open source RabbitMQ message queue middleware. The problem of two-way data synchronization between two data centers within an enterprise is solved. Through RabbitMQs message confirmation mechanism and persistence mechanism, the data can be delivered safely without loss. The experimental results show that the function of this data sharing module is stable, which can improve the data transmission efficiency and ensure its security.
