高可用性企业数据交换平台的设计与实现

为了使企业中构建在不同平台上的众多应用系统能够进行安全、可靠的信息交换,基于企业应用集成（EAI）的理念,提出了一种独立于原有系统、具有星型拓扑结构的高可用性企业数据交换平台解决方案。该平台采用通信层、服务层及适配层三层架构应用模型。对构成平台的这三个层次进行深入研究,说明设计实现的方法。此外,为保证平台的高可用性提出了以内存镜像为基础的双机热备算法。该平台的实现不仅能为企业中各应用系统提供高可用的数据交换,而且还可对数据交换的过程进行集中监控和管理,大大提高了数据交换的可管理性与可扩展性。

Design and Implementation of Enterprise Data Exchange Platform with High Availability

In order to make safe and reliable information exchange among large amount of applications constructed on various platforms in the enterprise,a solution of enterprise data exchange platform with high availability is introduced which is of star topology and independent of the existing applications based on concepts of Enterprise Application Integration（EAI）.The platform adopts an application model with 3-layers architecture（communication,agent and adaptor）.The design and realization methods for the 3-layers architecture are elaborated,and an algorithm of dual-computer hot-standby based on memory mirroring is proposed to guarantee the whole platform＇s high availability.The implementation of the platform not only can provide highly available data exchange for various applications of enterprises,but also accomplish centralized monitoring and management during the data exchange procedure,so as to greatly increase the manageability and expandability of data exchange.
