Design And Implementation Of Authentication And Accounting System Of Broadband

The object of this thesis: using the current popular memory database technology and distributed cloud storage concept, relying on the existing Shanghai Telecom broadband authentication and accounting system of the overall technical architecture, through the collection, collation of the front-end business sector demand, broadband authentication and accounting system platform based on RADIUS protocol to build a unified. In addition, the use of broadband user record data mining, user behavior analysis, and provide a theoretical basis for the management decision makers.The main problem of the broadband authentication and accounting system currently used in the system:1.Room no room for expansion room, can not simply rely on parallel increases the server to improve system performance.2.The key equipment is old, unable to support the new business(such as dynamicspeed)3.System message processing capability is insufficient4.The group proposed the user intelligence recognition request, and the original design structure conflict5.Version compatibilityThis thesis is in response to these above problems, with Shanghai Telecom certification system as the main object of study, through comprehensive analysis and understanding within the framework of the system and data to analyze how to adopt new technology to boost performance, the regulated sector demand.Analysis of the feasibility of the system:After some of the early users of memory certified pilot, after technical pre-research and feasibility analysis, in order to equip the system with high performance processing power, sudden peak has a better ability to resist, decided to adjust the billing system architecture to optimize system software upgrades; and the use of commercially available main memory database and realization of network-wide authentication user memory. Lifting capacity at the same time, reduce as much as possible the number of hosts under the same node, reduce system operating power consumption, ease of system maintenance and management. The new system uses a distributed cloud storage technology, multiple node redundant offsite certification, avoiding backbone network 1 node failure and impact on this system. In the design of programmes, but also on the original node within the near future as the expansion server uses the good old way, avoid the redundant investment, achieve full utilization of available resources.In order to comply with the operator management requirement, meet carrier-grade business application needs, under the premise of ensuring data accuracy and effectiveness of the new system, memory certification performance into full play, Shanghai Telecom broadband users authentication, operating data mining, driving business development. This paper focuses on in-depth study of broadband users authentication and accounting principles, combined with the memory certification and cloud storage technology, to achieve stability, reliability, security, disaster recovery, fault-tolerance and other requirements, requirement analysis, preliminary design, detailed design and system specific functional goals such as achieving a sufficient proof.
