通信层数据交换中间件设计实现

摘要

In order to solve the problem of the large data exchanging, varied data packet format, data's using and managing, in the communication level of enterprise information system, a universal data exchanging middleware is designed. The solution based on the tech of DLL, ACE (adaptive communication environment), XML, can solve the problem of data-frame defining in XML, dividing packet in TCP Sticky packet, data-stream compressing and failure-detecting, enhance the data exchanging and using ability, provide the node's failure detecting.%针对企业级信息系统通信层数据交换量大,数据帧编码协议不统一,难于利用和管理的问题,设计通用数据交换中间件解决方案,将系统的数据通信层独立封装,利用DLL、ACE(自适配通信环境)、XML等技术为上层应用提供数据交换服务.设计了基于XML的数据帧结构、TCP粘包处理算法、数据流压缩、节点故障检测技术等.适配器便于数据共享与集成利用,并提供节点故障发现能力.
