Research And Implementation Of The AAA Module In IPTV Platform

Since2005, the Radio and Television issued the first IPTV license, IPTV system rapid development in our country to promote IPTV technology continues to progress, with the increase of the user base and coverage, as well as the practical application of the depth. It provides the mainstream based broadband Internet access means extensive use of the Internet to provide users with superior audio-visual experience. A complete IPTV system including business management platform, the operational capacity of the platform, the IP bearer network and terminal. AAA (authentication, authorization, accounting) subsystem is one of the core.On the platform of the paper-fung SWIT integration of video systems, research, design, build and perfect the part of the backbone of the the IPTV operations support systems:AAA subsystem and software management platform.This article from the architecture of IPTV systems, introduces IPTV system architecture, system components, system interface. Leads to the specific architecture of the IPTV the AAA system’s design requirements and user authentication, user service authorization, service process billing, user management, billing, policy management, server performance management aspects specific design for the AAA server after the specified direction. After that, according to the system requirements and AAA’s relations with other subsystems, designed the the AAA subsystem data table structure, and the flow of the interaction with other subsystems. Then we detail the AAA server in the implementation of key technologies, including the AAA backup technology, database failure recovery. AAA server performance tested in actual network environment, including the performance of the single cluster, scene execution results, downtime performance aspects of the implementation of the results of scene.
