【摘要】 随着Internet网的快速普及与应用，对网络用户和网络资源需要进行高效地管理，网络计费系统在网络管理中起着越来越重要的作用。 论文将从网络应用协议和计费系统架构两个方面，提出网络计费系统设计和实现的方法。首先根据网络用户对网络资源的不同服务质量需求，分析了Internet的QoS机制，给出了网络计费系统中应用QoS机制的计费方法。针对网络用户使用网络资源的实际情况，对网络用户采用不同的计费依据，利用RS232协议、RADIUS协议，SNMP协议采集程控电话用户、拨号用户、路由用户的计费数据。其次，考虑到网络计费系统分布式应用的趋势，将计费系统的各个功能模块集成到CORBA软总线上，使计费系统功能模块架构具有开放型和扩展性。最后，在应用平台上对计费系统应用模块进行了功能描述，同时阐述了实现思路。通过上述的解决方案，能够设计和实现强有力的网络计费系统。 在计费系统实施的整个过程中，利用分布式对象接口方法来支持系统的分析、设计和实现，实践表明分布对象接口技术给系统的开发提供了坚实的保障。更多还原

【Abstract】 With the rapid prevalence and appliance of Internet, network users and network resources need to be supervised effectively. Thereofore network accounting system perform more and more function in network management nowadays.This paper present a solution to design and implement network accounting system from two aspects in which network applicace protocol and accounting system construct are included. Firstly, the QoS strategy is analyzed to bill users which have the various quality requirement to network resoures and a method is given to adopt the QoS strategy in accounting system. Aiming at the factual case that ueser share different network resources and accountig standard, accounting data is collected by RS232 protocol , RADIUS protocol and SNMP protocol. Then function modules of accounting system are integrated on CORBA soft-bus and had the performance of opening and expandability to match the trend of distributed application demand. Finally, the modules are described and drew out in detail on application platform. According to the project, the better accounting system is gained.During the whole process, the idea based on distributed object interface is used to support analysis, design and implementation. The conclusion is that the thread is powerful.更多还原
