Automated integration of real-time and non-real-time defense systems

Various application domains require the integration of distributed real-time or near-real-time systems with non-real-time systems.Smart cities,smart homes,ambient intelligent systems,or network-centric defense systems are among these application domains.Data Distribution Service(DDS)is a communi-cation mechanism based on Data-Centric Publish-Subscribe(DCPS)model.It is used for distributed systems with real-time operational constraints.Java Message Service(JMS)is a messaging standard for enterprise systems using Service Oriented Architecture(SOA)for non-real-time operations.JMS allows Java programs to exchange messages in a loosely coupled fashion.JMS also supports sending and receiving messages using a messaging queue and a publish-subscribe interface.In this article,we pro-pose an architecture enabling the automated integration of distributed real-time and non-real-time systems.We test our proposed architecture using a distributed Command,Control,Communications,Computers,and Intelligence(C4I)system.The system has DDS-based real-time Combat Management System components deployed to naval warships,and SOA-based non-real-time Command and Control components used at headquarters.The proposed solution enables the exchange of data between these two systems efficiently.We compare the proposed solution with a similar study.Our solution is superior in terms of automation support,ease of implementation,scalability,and performance.     

基于CDMA和JMS的后勤应用系统数据通信方案研究

数据通信是后勤领域应用系统中亟待解决的重要问题.大部分接入军事综合信息网的单位,可利用该广域网,采用JMS消息服务技术,实现分布式系统数据通信.尚未接入军事综合信息网的单位,可以依托专用CDMA无线通信网络,该网络覆盖面广,通信可靠,建立迅速,维护费用低,能够实现安全、及时地传输业务数据.两者结合,将构成一个全方位、一...

基于公平谓词法的JMS消息过滤改进算法

研究了JMS发布／订阅消息传递模式的工作机制，分析了JMS在对事件进行匹配时的过滤算法，针对该算法的不足提出了采用公平谓词法来改进JMS的消息过滤速度，改进方法对基于JMS的发布／订阅应用程序的开发具有一定的指导意义。
