| According to the requirements of heterogeneous and distributed users, how to ensure the business management, data sharing and stable data transmission in heterogeneous and distributed environment has become a very urgent problem. The message is the basic unit of information exchanged between distributed application data, messaging middleware, support and protection between distr ibuted applications synchronous and asynchronous messaging, the communication interface betwe en distributed applications is provided by the messaging middleware.This paper aims to study the existing problems of the product, provide a highly reliable distributed messaging middleware system. The system is capable of highly reliable messaging features, reasonable regulation of the load status of each node in the cluster, to avoid some of the nodes because the load is too large to enhance system instability; for news production to further control the flow, the flow in the system It can be maintained in good working order when the sudden rise or traffic plummeted, and unified management for the cluster metadata. This paper developed messaging middleware named Vessel MQ, which is generally divided into message publishing, message subscription, Name Server metadata management, Broker module and supporting management services. Message Publish interfaces and message subscribe interface provides the calling of the user service system and processing system, publish the news publication and subscription of consumption, Name Serve for metadata management system service, is responsible for the maintenance of the metadata of cluster nodes, the broker is responsible for message forwarding and storage landing.The implementation of this system degresses the coupling bet ween Busine ss Systems and Process systems significantly. Consequently, it meets the requi rements of the company, which includes hightly reliability, concurrency, stanbil ity when message has been transferred. This systems will be used brightly. |
