As a component of message oriented middleware ismq , message transfer agent ( mta ) , which implements reliable message transfer service , delivers messages among ismq servers . based on the study of failure models , we introduced a reliable message transfer protocol in mta 消息传输代理mta是消息中间件ismq中的一个子系统,该子系统完成消息在服务器和服务器之间转发的功能,是分布式系统结点间可靠消息传输的实现。
The communication model is a twp - tier architecture , the main function of superstratum ( name server ) is tracing the domain which target agent belong to presently . the main function of substrate ( domain - inside tracing machine ) is the message transfer and denominating the new created agent 本文所提的通信模型分为了两层结构,上层的名字服务器主要提供按名字追踪目标agent所属域的功能,下层的域内追踪器完成消息转发及为新生agent命名的功能。
The activex controls shows the runtime status of the monitor object associated with each other . those controls realize the data transmitting and message transferring in the monitor system . the activex technology enables the application system to access remote data as dom documents 在监控系统软件的集成时,利用activexserver和activexcontainer技术并使系统支持activexdocumentserver ,使该应用系统软件以dom形式远程访问成为可能,为监控系统软件的版本升级打下基础。
The contents are as follow : 1 、 introduced the web service technology and it ’ s usage . described the usage of the modules of service - oriented architecture ( soa ) , the relied protocols , the realization ways , the three roles of the architecture , the way of message transfer and the advantage of soa 主要叙述了面向服务的体系结构( service - orientedarchitecture , soa )的各组件的作用、各自依赖的网络协议和实现技术、面向服务体系的三个角色和它们之间消息传递的机制,以及面向服务体系结构的优势。
Based on the discussion of middleware , this thesis demonstrates the history , the concept , the classification and the characteristics of middleware , and it discusses the general - used middleware , such as transaction processing middleware and message - oriented middleware , and especially demonstrates the implementation and feature of message queue - oriented middleware and message transferring - oriented middleware 在探讨中间件技术的基础上,本文概述了中间件技术的发展历史、中间件的概念、分类、中间件的特点等基础知识,并对交易中间件、消息中间件等几类常用的中间件进行了讨论,着重论述了面向消息队列中间件和面向消息传递中间件的实现机制和特点。
