Design And Implementation Of Shanxi Telecom Broadband And Dialup Radius Server

This paper is a crystallization of the actual project development experience and initial results. The Author collect, organize and access large amounts of data, then completed the paper.The paper describes the current status of Internet development in the country, Shaanxi status of broadband users, domestic and international developments, the current mainstream of the authentication and ccounting systems and related products were reviewed and summarized.The paper involve in the system’s main technology: shared memory database technology, PPPOE protocol, Radius protocol, Diameter protocol, distributed computing technology CORBA, load balancing techniques are analyzed and studied.The paper writes the entire system design, which not only describes the design of network hardware, but also describes the system software architecture design (the entire software system is designed to four structures:a database layer, object layer, business layer, application layer)。On this part, the overall design of the database shared memory is descripted Detailed, and adds some icons properly to make content more comprehensible expression. The paper descripts the implementation of the whole system detailed, both relates to the core of the system (such as:authentication, accounting) implementation, is also related to the shared memory database,which is a part of base functions. In this part, classes list and classes relationship are used to describe the system’s main object and mutual relationship, and descripts the core encryption algorithm. The paper describes the project product testing after the completion of the project, In this part, the testing method, tools, programs and test results are illustrated. Finally, the paper is a summary of the work of the project, future technology and related products in the development are imagined, especially in authentication and accounting system and the integration of existing systems are imagined.This transformation of the original overall system performance by100%, authentication and accounting packets from the original concurrent processing capabilities150, raise to300. Processing speed upgrade from the original3seconds to1.5seconds. The product development project and get praise from all sides.
