基于发布订阅机制的态势信息实时分发框架

摘要

针对战场态势分发信息量大、实时性要求高、不同用户需求差异大的特点,提出了一种基于发布订阅机制的态势信息实时分发框架.构建态势元数据模型,能够描述战场态势信息和需求方的偏好,将态势更新看成发布事件,需求方看成订阅者,设计基于态势数据元模型设计合适的匹配算法.在此基础上给出了态势信息实时分发框架,能够指导构建面向服务架构的新型战场态势信息分发系统.%The battlefield has a large amount of information to be distributed real-timely,and the information also has different characteristics in user demand.To solve them,this paper presents a battlefield information real-time distributed framework based on the publish/subscribe mechanism.Firstly,a meta-data about the battlefield information is constructed,which can describe the information of the battlefield and the preference of the demanders.The update of the battlefield is as the publish event,and the demander is as the subscriber.Then,the appropriate matching algorithm is designed based on this meta-data.Finally,a distribution framework of battlefield information is proposed on this basis,which can guide to build the new service-oriented battlefield information distribution system.
