摘要

摘要: 互联网目前已经发展为一个由实时视频和视频点播等内容分发服务主导的网络.传统IP网络对于视频分发类任务的支持存在组播的部署复杂且开销大，不能有效利用多路径获取内容、对移动性的支持差和难以同时满足可靠性以及低延时需求等问题.命名数据网络(named data networking, NDN)作为新型的下一代互联网体系结构，支持网络内缓存和多路径传输，而且由消费者驱动的传输模式使其天然地支持消费者端移动性.以上特点使NDN具有高效传输视频内容的潜力.首先介绍了视频传输和NDN的基础背景，然后阐述了一些利用NDN中优势实现视频传输的设计方案.通过对已有方案的总结与比较，最后指出了在NDN中传输视频所面临的挑战.

Abstract: The Internet has developed into a network dominated by content delivery services such as delivering live and on-demand videos. There are some problems in traditional IP network in terms of supporting video delivery, such as the complexity and high overhead of the deployment of multicast, the disability to effectively utilize multipath transmission, the poor support for mobility and so on. Named data networking (NDN), a promising future Internet architecture, intrinsically supports in-network caching and multipath transmission. Consumers actively use interest message to request data packet from producer, and this consumer-driven communication model enables NDN to naturally support the mobility of consumers. These features offer the potential for NDN to efficiently deliver videos. This paper first introduces the background of video delivery and NDN, and then elaborates some schemes that take the advantages of NDN to deliver video: firstly, how do the strategies in NDN improve video bit rate; secondly, how do the strategies in NDN improve video playback stability; thirdly, how do the strategies in NDN protect video copyright and privacy; finally, how do the strategies in NDN transfer new types of video. According to the analysis of these existing schemes and the comparison of their performance over IP and NDN, the challenges of delivering videos over NDN are finally pointed out.
