【摘要】 在通信网向大容量、标准化发展的今天, SDH技术以其强大的组网能力已成为传输网发展的主流。与此同时,也对SDH网络及其设备的管理提出了新的课题。开发一个功能完善、符合统一标准的SDH管理系统对整个SDH网络的服务质量及维护成本都有着深刻的意义,是网络能够得以高效灵活运行的重要保证。为了SDH网络管理系统更协调、更流畅、更稳定地运行,如何解决SDH网络管理系统中各个管理模块之间的通信问题,就成为了摆在设计者面前的一个重要课题。本文针对SDH网元管理系统的企业级开发过程,介绍了JMS和消息驱动Bean的技术原理,分析了JMS的体系结构和消息系统模型,根据网管系统的实际需求,讨论了如何在SDH网元管理系统中应用JMS技术,以构造一个符合松耦合的、可靠的、异步通信要求的J2EE企业级应用系统。本文从异步消息传递的角度对系统进行总体设计,采用以点对点模式发送和消息驱动Bean异步接收的方式,实现了南向接口和服务器端之间的事件通信,同时,采用发布/订阅模式和消息侦听器异步接收的方式,实现了服务器端和客户端之间的事件通信。通过异步处理的方式,减少了各个模块之间的耦合程度,使得各个应用程序之间实现了松耦合,提高了系统的可靠性,便于系统的管理与拓展。最后论文总结了JMS技术在网管系统中应用的优点,以及今后的改进方向。更多还原

【Abstract】 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.更多还原
