The Research And Implemention Of MOM's Key Technologies

Message Oriented Middleware is a message-middleware based on distributed system; and it acts as a message system providing reliable and stable communication platform for inter-node. It can be based on different protocols, hardware platforms, languages and operating systems, which providing reliable distributed systems solution to facilitate communication and application integration.During the research of distributed network management system, we found that there were some deficiencies, such as synchronous communication, client-server tightly coupled, and only peer to peer communication. Based on this, design and implement a messaging middleware system——SPMQS.The current messaging middleware faces the complexity and non-reliability of the environment, so the thesis design and implement the cluster service, which can not only replicate a session but also be an effective solution to resolve single point of failure. It is able to switch machine between the distributed nodes. Results show that the cluster service can be normal and implement session replication such as automatically switches the machine so as to support reliable distributed communication nodes.Aiming to solve the sensitivity of corporate datum, the thesis introduces the advanced algorithm——Rijndael algorithm. The thesis analyzes its principles of encryption and decryption, and carried out in the SPMQS. The formation of API facilitates the secondary development and the integration of distributed system applications to ensure the security of enterprise information.How to handle the multiple client-connections and deal with a number of messages have been a key problem, the thesis uses the IOCP to explore the effectively of massive client connections. Additional, it studies the asynchronous message delivery modes, such as point to point and publish/subscribe communications, and analyzes the look-up and routing services technologies.
