【摘要】 随着Internet的发展,网络的规模和复杂度越来越大,信息技术的应用模式发生了很大的变化。为了保证网络的运行效率和性能,网络管理技术正朝着分布式和Web化的方向发展。SOA(Service Oriented Architecture,面向服务的构架)是一种有效解决异构性所产生问题的新的体系架构,其思想是提供统一接口,通过服务的发布、服务的发现以及服务的调用等机制为其他的应用程序提供服务。这使得构建在各种这样的系统中的服务可以以一种统一和通用的方式进行交互。通过采用SOA框架,企业可以最大程度地减少系统间地耦合,从而提高系统组件的可重用性。Web Service技术为本系统的开发提供了技术支持,Web Service技术使基于SOA的系统的实现成为可能。本文在深入分析了这些基础理论后,针对分布式网络管理的特点,系统的阐述了基于SOA的分布式网络管理系统。主要研究内容包括:首先对系统进行了总体设计,主要包括整个层次和架构的划分,核心地方用到的设计模式,这是本文的一个研究重点;其次详细阐述了该系统的实现,特别是业务层中Web服务的构建和设计,持久层设计方案、安全策略的研究与实现,这是本文研究的另一个重点;最后,是系统的功能测试和性能测试部分,验证了该系统的优越性。研究内容重点包括业务的设计与实现,在整体采用J2EE构架的基础上应用Web Service技术开发应用程序以及系统的设计模式和安全策略,并对实现中存在的技术难题进行详细分析。更多还原

【Abstract】 With the development of Internet, the scale and complexity of networks has increased greatly, and the application pattern of information technology has changed greatly. In order to guarantee the execution efficiency and performance of networks, network management technologies are developing towards distribution and Web.SOA (Service Oriented Architecture) is one of new architectures to resolve the problems caused by isomerism effectively. The mainly ideology provides with a uniform interface, and provides services for other applications through service publishing, finding and invoking. All services build on different systems can communicate by uniform method. Through SOA framework, enterprise can reduce coupling between systems in most extent and enhance the reuse of software.Web Service technology has provided the important theory support for the development of this system; it makes the realization based on the SOA theory into possibility. After thoroughly analyzing these basic theories, aiming at characteristic of distributed network,this paper expound the research and the application of distributed network based on SOA. The main research content includes: First ,this paper design whole system, mainly includes the entire layer ,the architecture and the design pattern in the core model which is a key part ; then, in introduce realization of this system, specially how to design and construct a Web service in the business layer, the design proposal in the data layer , the research and realization of security policy, this is the other key part; Finally, the last part is the function test and the performance test which confirmed superiority of this system. The important research content includes the design and the realization of services, applying Web Service technology on the development on the foundation of J2EE skeleton as well as the design pattern and the security policy of system, and analyzing the difficult technical problem which exists on the implement process.更多还原
