Design And Realization Of The Connection Service Sub-system In The Broadband Accounting System

The high-speed broadband networks are becoming increasingly popular. Within a few years, high-speed broadband Internet network occupied most of the market. Video-on-demand, online remote medical service, such as real-time video conferencing on the Internet can not be realized in the narrow-band multimedia information services in the broadband Internet has been achieved. Along with the increase in the number of users, its existing and potential users of operator services provided by the proposed additional requirements. Single billing management model has been difficult to meet the needs of different users. At the same time, as operator, in order to make profit broadband network can also create a variety of content-based broadband services. Each user to choose different service projects, the costs charged by different networks.Thus, with the development of broadband networks, network management and billing issues become increasingly prominent. Currently, broadband MAN management is not yet complete; users do not improve billing methods. Ancient single monthly rates are difficult to cope with the complex and diverse needs of users'type. For these reasons carriers implemented by a flexible and diverse rates.The various charges of the existing standards together, as a full-featured, and the future unified broadband billing system, a radical improvement in these problems to achieve the entire broadband billing and integrated management. But more importantly, after the new fee demand will be directly incorporated into the broadband billing system .Netcom Broadband Billing System, Netcom broadband billing system is to satisfy all kinds of Netcom broadband rates, unified management and development projects. Its main purpose is to use the system to unify the management Netcom broadband services, broadband users at any time convenient for their own use (time, the flow, costs, etc.) for inquiries, to meet the telecom operators on the unified management of the broadband charges demand, but also has certain technical Application and forward-looking. The main purpose of this study was to explore broadband access services Billing System Design and Implementation.The paper said the specific work mainly contains the following contents: 1) On the current popular access, authentication, information filtering, and network management related products and technologies. Analysis of the system used by the PPPoE access technology, Radius authentication authorization technology, a state with no state firewall firewall combination of information filtering technology, SNMP network management agent technology.2) The realization of the system are related to the technology, the realization of the system applied to the needs of the relevant technology was introduced, and then on the technology in the system of an analysis of its analysis of how the system proposed in the application system of how to apply the technology ideas to the existing technology in achieving the application of the system, some new ideas. How the identities of the Internet users are certified and authorized by the system to solve an important problem, so the certification authorization technology is the application of systems analysis and the success in practice the key. Because of the system belong to the network access system, network security is the system can not avoid the issue. In this system of fire walls using packet filtering technology to users request access to the necessary information filtering application of the system in the packet filtering technology uses no state is a state packet filtering and packet filtering out ways to combine.3) Access service system design carried out a detailed analysis and introduced. First, the analysis of the three main applications of the system each corresponding workflow; Then, on the overall broadband billing system architecture and access service system architecture;Access modules in the design of the paper on the Linux operating system under the PPPoE server-side solutions to traditional in-depth study, the analysis of its deficiencies and proposed, which is based on the "single virtual device" thinking of the improvement program. The improved solution in dealing with all the conversation and links only need to create a virtual network equipment and a virtual terminal equipment, thus fundamentally solve the original online client restriction on the number of problems. In addition, since the program improved in the module division on the program followed the traditional practice, the implementation of the program has inherited the traditional high efficiency, good scalability advantages. After testing the program proved feasible and can achieve the desired results.Certification authority in the sub-module design, verification client was isolated as a separate daemon running, and the agreement of all its packaging process are in the shared library. The program not only reduce all of the coupling between modules, and increase the various sub-modules and the entire system robustness, but also to guarantee the good modules good scalability.Information filtering in the modules of the design, using state of the packet filter are stateless packet filtering and combining programs. Packet filtering is tracking the entire state communications processes, avoiding stateless packet filtering high-level agreement on the communication before and after the state of ignorance and ignorance of the natural defects.SNMP agent-in modules in the design of network management through SNMP and workstations communicate. Acting principal and adopt processes and MIB variables phase separation programs. Increase the flexibility of application of the MIB.Finally, the software modules to achieve the division, every module of the interior design were discussed in depth. Access service system to achieve the green and billing management system integrated Internet users access, authentication authorization; The green Internet users access to the necessary information filtering; For network management workstations provide relevant management information,4) Implementation of the system highlights several key technology areas (Access Module of the realization of authentication module empowers the realization of information filtering module of the realization of SNMP agent module to achieve) the realization of the details, the four modules of the procedures detailed data flow chart.5) Access to the entire system of two important sub-modules: Access son module, module-mandated certification test, the test access software modules, is divided into two parts: functional testing and strength testing. Functional test modules main function is to test the integrity of access, and strength tests are intended to limit certain circumstances test module performance and behavior. Give the test results and analysis. Finally, the system and the application software system were implemented by the effect. .
