摘要 提出了一个4层端到端无线环境基于IP的电视(IPTV)服务质量(QoS)实现构架,通过调度压缩编码技术、内容分发网络(CDN)技术、多播技术、点对点(P2P)技术、缓存技术和整形技术等,在动态和突发的IP业务量环境下为用户的IPTV业务应用提供端到端QoS传输保证.仿真结果显示,通过合理的指配和调节,在真实的Internet环境中,机制可以满足标清电视的QoS要求. A four-tied Internet protocol television(IPTV) quality of service(QoS) implementing architecture is presented in wireless environment. By collaborating compression encoding, content distribution network(CDN), multicast, peer-to-peer((P2P), cache, reshape, etc, in dynamic and bursting IP traffic environment, end-to-end QoS transport for user IP TV service application will be assured. Simulation result shows that, by rationally provisioning and adapting, it can provide the bandwidth required by standard-definition TV(SDTV) in real Internet.
