The Research And Design Of Network Service Accounting System Based On Proxy

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.
