Abstract：
Distributed message queue storage of data is an existing general solution, but there is a defect that emergency services
are difficult to be processed as priority. The purpose of this research is to provide a system for invoking distributed switching net
elements based on message priority queues to solve the problem of the prior art that cannot process orders according to priority
by increasing the number of message queue topics and calling the Json microservice ticket splitting module. The system can sim
plify business logic, improve system efficiency, and ensure that multiple hosts and multiple nodes work at the same time. It plays
the role of load balancing and automatic switching.
