An Application Of JMS In SDH Network Element Management System

The current trend towards developing large-capacity and standardized communication networks makes SDH the mainstream transmission network, and the management of SDH network and its facilities is thus a project worth exploring. A sophisticated and standardized SDH management system is of crucial significance in determining the operation, service quality, and maintenance cost of the whole SDH network. In order to make the SDH network management system run more harmonious, fluent and stable, we have to figure out how to solve the communication problems between different management modules.With regard to the enterprise developing process of SDH network element management system, the current paper introduces the technical principles of JMS and Message-Driven Bean and analyzes the JMS architecture and message system models. According to the practical demand of the network management system, this paper discusses how to use JMS message in SDH network management system so as to construct a J2EE enterprise application system which has loose coupling and reliable and asychronism communication. The present paper focuses on asynchronous message transferring and described the complete design of the system. By using Point-to-Point pattern in message sending while Messaged-Driven Bean in message receiving, the event transferring between the SouthBound module and the Server module is accomplished. By employing Publisher/Subscriber pattern to send out messages and Message-Listeners to receive them, the event transferring between the Server module and the Client module is achieved. By taking JMS as the structure of asynchronous message transferring, the coupling between management modules is loosened, the reliability of the system is strengthened and future updating of the system is well-prepared. In the end, merits of JMS application are summarized and directions for further development are listed.
