Design And Implementation Of The Hfc Network Data Services Billing System

As one of the five primary functions of network management, accounting management plays more and more important roles. Especially nowadays, when information become one kind of strategic resources and networks are used in commercial areas, how to manage networks, especially how to charge for using networks, is becoming a hot point in the network development process.Meanwhile, accounting management is also a hard point. What it faces is complex network environments, various network applications, varying accounting policy and varied network users. Moreover it involved many kinds of knowledge and technology, such as operating system, network architecture and protocol, data compression and network security. How do you collect the original data on the network? How do you compress the data already collected? How do you arrange information? How do you transfer data safely? All these problems must be handled. In the process of designing and implementing Shenzhen HFC network data transaction accounting system, the author of this paper studied these problems carefully.HFC network data transaction accounting system solved these problems successfully. Different from other accounting software, HFC network data transaction accounting system is an integrated network accounting system. It integrated data collection, data process and information management. And it can adapt to various network environments and it can use different accounting policy depending on different user and different access. And furthermore, it can implement various networks traffics statistics. Meanwhile, it can monitor the system and trace the illegal access, and so on. In theory, HFC network data transaction accounting system uses the mode of monitoring packets on the data link layer to collect data, merges the packet according to the characteristic of transferring packet on the network, uses data compression and encryption technology to transfer accounting information to the manager station. On the basis of the data collected, it constructs a web-based integrated accounting management system.There are many advantages in the implementation of this system.(1) Connecting the stations collected data in parallel instead of in serial mode has less influence on the network.(2) Merging and compressing accounting information enhances the efficiency, and therefore reduce the cost for transferring accounting information.(3) Data are encrypted before transfer, and this certainly enhances the security of the system.
