【摘要】 随着网络经济的迅猛发展,计费系统已经成为网络应用中的一个极为重要的组成部分。目前市场上的计费产品有很多,但基本都是“以业务为核心”的系统构架,一般只能为一种特定的网络服务进行计费。各个网络服务的计费系统之间不能兼容,已经越来越不能满足网络经济发展的需要。为了解决以上问题,本文给出了一种“以用户为核心”的通用网络服务计费系统的设计与实现。本文首先研究了当前各种类型网络计费系统的发展现状和各种计费技术的优缺点,然后针对目前网络服务计费系统存在的不足,给出了一种与网络应用无关,能够同时支持多种网络服务的“以用户为核心”的网络服务计费系统的设计思想,并设计了以Socks5协议为基础的基于代理服务器数据采集的通用网络服务计费系统实现方案。接着按照设计方案建立了本系统的体系结构,分析了本系统各个组成部分以及各部分之间的交互过程。对于设计方案中的两个关键技术问题:计费网关的性能瓶颈和客户端网络数据的截取与转发,本文也进行了详细的研究,通过对多种解决方法进行了分析和比较,选择了比较理想的解决方法。最后对本系统中的计费客户端、计费网关、认证模块和计费后处理等几个主要部分的具体实现过程进行了详细的讨论。本系统完成以后,经过试用取得了比较满意的结果,达到了设计要求。证明了“以用户为核心”的网络服务计费系统的设计方案是完全可行的,并且在网络经济有巨大的实用价值。更多还原

【Abstract】 With high-speed development of network economy, network accounting system comes into being, and becomes an important part of the network applications. There are many products of network accounting system in the market but most of them that based on the services have some disadvantages in extensibility and flexibility. The accounting systems of each network service can’t be compatible with each other, so that they can’t meet the demand of the fast development of network economy today.In order to find a solution to these problems, this paper firstly studies current situations of the development of all kinds of network accounting system including the advantages and deficiencies of different charging technology, and then proposes a new design of the accounting system based on users, which has nothing to do with network services, and can not only apply to various kinds of network services, but also charge for a lot of network services at the same time. After that this paper provides a design plan of general-purpose accounting system of network service that is based on Socks5 protocol and collects data through proxy server. Then this paper builds the architecture of this system according to the design plan, including the introduction of each component and the interactions among those components.The two key technologies of this design plan: performance bottleneck of the charging gateway and intercepting of the client network data are carried on research carefully and given the rational solutions. Finally, this paper gives a detailed discussion of several important parts of the system such as the charging client, the charging gateway, authentication module and the management after charging.After this system is converted to a commercial product, it reaches the design requirement. It is proved that the design of the accounting system based on users of network services is feasible, and can make practical value in network economy.更多还原
