文档介绍：摘要摘要近年来,中国医院的信息化建设取得了一定的成绩,有些医院已经初具规模。但是,各个医院的信息系统之间数据无法实现共享,造成资源的严重浪费。为此,我们提出了区域化PACS系统的概念,通过院间信息的完全共享,消除信息孤岛,减少医疗资源浪费。为了配合区域化PACS系统的建设,本课题通过对群集系统的深入研究,网关部分进行优化,达到高可用性。标准技术文档。然后对PACS系统架构进行了阐述,介绍了富有特色的三层PACS构架和基于区域化的PACS模型。然后,分析了基于Linux的LVS群集技术,介绍了群集的类型、特点、以及动态漂移技术,并介绍了LVS群集的实现方式和负载调度算法。通过比较,选择了VS/网关的群集解决方案。最后,网关群集系统(DCS)的接收模型和服务模型,网关的高可用性。并且针对方案中存在的单点故障问题,通过动态漂移技术,设计了群集调度的优化解决方案。基于Linux的DCS模型的设计和实现,为区域化PACS系统的推进,提供了强有力的支持。关键词:PACS,,LVS,DCS,LinuxAbstractAbstractInrecentyears,constructionofinformatizationofChinesehospitalshasattainedcertainachievements,,,,,gatewayofthePACSSystem,,,itanalyzesLVSclustertechnologybasedonLinux;andthenintroducesthetype,characteristicsanddynamicdriftingtechnologyofthecluster,andrealizationmeansandloadschedulingalgorithms ,itchoosesVS/,gatewayclustersystem(DCS)arebuilt,,:PACS,,LVS,DCS,Linux目录目录摘要„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„IAbstract„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„Ⅱ目录„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„Ⅲ第一章绪论„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„2第二章 标准研究„„„„„„„„„„„„„„„„„„„„„„„32
