摘要
当前互联网视频质量普遍偏低,高清视频将是未来互联网视频的发展趋势。利用应用层组播技术承载高清视频直播业务能有效地降低网络建设成本、解决P2P及传统CDN技术承载视频直播业务中存在的问题。通过分析应用层组播原理,提出一种基于应用层组播技术的新型网络架构,分析了通过应用层组播实现互联网高清视频直播业务的技术特点、商业模式、市场推广策略和关键流程等。
The quality of Internet video is low generally now, high-definition video will be the mainstream trend of Internet video in the future. The use of application-layer multicast technology carrying high-definition video broadcast service can effectively reduce the cost of network construction and resolve the problems which exist in P2P and traditional CDN technologies. By analyzing the principle of application layer multicast, a new network architecture based on application layer multicast technology is put forward. Meanwhile, the features, commercial modes, market promotion strategies and key processes of the high-definition video broadcast service are analyzed
