一种IPTV动态权限变更系统的研究与实现

Research and Implementation of a Dynamic Authorization Management System for IPTV

本文针对在以大规模接入汇聚路由器(ACR)为核心构成的有线宽带双向接入网络中"静态用户认证状态表"机制不能解决实时授权的问题,提出了基于用户授权信息变更(CoA,Change-of-Authorization)协议的实现方案,该方案不仅能实时更改用户授权,并且具备简单、可扩展、安全等优点。

The paper aims at the failture problem of changing user authorization dynamically using the Static User Authorizaton State Table in the dual Cable Broadband Access Network environment based on ACR（ Access Converging Router）. proposes a new implementation scheme based on CoA （Change of Authorization） Protocol. This scheme can not only change user authorization in realtime, it is also advantageous for its simplicity, scalability and safety.
