Aaa Subsystem Epon Operation Support System Design And Realization

These years, as Information Technology take more and more important position in social life, broadband became necessary to home network access, and also it is the one that carrier operator wants to push on. Currently, ADSL, xDSL, FTTB and Cable Modem still have some distance to people requirment, and they can't offer enough performance and quality to Net-Meeting, VOD and VOIP. Based on the popularity and low cost with high bandwidth of Ethernet and the large capacity of Fibre Network, a technology named EPON, which is a Positive Optic Network based on Ethernet, come to be one of the best choices for next generation broadband access networking.A strong and stable OSS, which not only ensures easy and stable networking to user, but also manageable and flexible infrastracture to operators, is necessary to this new network architecture and will benefit both sides. AAA (Authentication, Authorization, Accounting) is the key of OSS, in this theis, the AAA protocols and application requirement is analyzed first, and then the design the implementation of AAA subsystem are described in detail including following topics:Introduced basic concepts of FTTH based on EPON, then show the whole architecture of our FTTH network;Analyzed OSS architecture running on broadband system and the AAA subsystem;Analyze and design AAA component in detail, in which we make out the solution through problems and integrated them to the whole system;Extended standard RADIUS protocol and focus on the designation and implementation of authentication based on WEB;According to the designation and implementation in my work, I designed a series testing, and improve original designation through test;...
