摘　　要：网络电视(IPTV)的设备提供商与运营商拥有各自的用户认证、授权与计费系统,各系统间互不兼容且性能差异大。该文根据AAA的原理与IPTV系统的业务特点,提出一个基于IPTV系统的统一AAA服务器的设计方案。系统采用AAA最新的Diameter协议,优化认证、授权和计费过程,通过引入高速cache,解决大量访问造成的性能瓶颈。实验证明了该方案的可行性。Many IPTV companies provide their systems of authentication, authorization, accounting, but the systems are not compatible and their capability are not excellent for IPTV system. According to the theory of AAA and IPTV model, this paper gives a whole solution on AAA server based on IPTV. By using Diameter protocol, it optimizes the processes of authentication, authorization and accounting, and uses cache to resolve the capability bottle-neck of system. Simulation experiment verifies that it is effective.
