| 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. |
