【摘要】 分布式的监控环境中,基于发布/订阅的push模式能及时地反映用户关注的最新信息,很好地满足松散通信的需要。但当订阅条件关联多条数据信息时,传统的订阅描述方法和匹配算法难以满足要求。提出了基于ECA(event-condition-action)的信息发布/订阅机制,利用ECA规则描述复杂的订阅条件,并初步研究了匹配方法。介绍了在卫星测试中该机制的设计实现及应用。更多还原

【Abstract】 In the distributed surveillance system,the push method based on public/subscribe system offer the latest information in time.It meets the demand of relax communication well.But when a subscribe rule refer several information,traditional publish/subscribe method doesn’t satisfy this requirement.A publish/subscribe system is described,which defines the subscribe conditions by ECA rules,and pilot studies the matching method.Then the design and application of this publish/subscribe system is presented in satellite test.更多还原
