企业服务总线研究综述

企业服务总线（Enterprise Service Bus，ESB）结合事件驱动技术，提出了一种新的服务连接架构，以实现服务间基于标准、松散耦合的通信方式，为基于服务的系统集成和扩展提供了更有效的支持。本文首先介绍了ESB的基本概念，然后从消息机制、消息转换、消息路由、服务容器四个方面分析了ESB核心功能组件，讨论和比较了当前主要的ESB软件产品和开源项目。ESB技术尚处在发展初期，本文分析了ESB研究目前存在的主要问题以及今后研究方向。

A Survey on Enterprise Service Bus

ESB (Enterprise Service Bus) is a key infrastructure for SOA (Service-Oriented Architecture)with event- driven technology. It is a new architecture which connects standard-based and loosely-coupled services. ESB enables transparent system integration and enhances system extensibility. This paper first introduces the general concepts of ESB. It then analyzes the state-of-the-art research on the four key components in ESB, including message mechanism, message transformation, message routing and service container. The paper also introduces major ESB products and compares three open-source ESB projects. It finally discusses the main problems of ESB and future research directions.
