移动视频变得异常流行，P2P移动视频平台也在这种背景下被考虑大规模部署。然而，实际P2P视频系统的设计和部署必须考虑移动网络的具体特征。在本文中，我们从大型商用P2P移动视频提供商系统PPTV的角度出发，描述了基于3G网络的P2P移动视频系统的实施挑战。我们的分析有 PPTV 的真实测量和经验支持。我们从这些测量中提取移动视频的特征，并分析它们对 P2P 视频系统的影响。我们还简要讨论了PPTV移动P2P系统设计中的其他实际问题。
Mobile video is becoming extremely popular, and P2P mobile video platforms are being considered for large-scale deployment in this context. However, the design and deployment of realistic P2P video systems have to consider specific characteristics of mobile networks. In this article, we look from the viewpoint of a large-scale commercial P2P mobile video provider system, PPTV, and describe the implementation challenges of a P2P mobile video system over 3G networks. Our analysis is backed by real measurements and experience from PPTV. We extract from these measurements the characteristics of mobile videos and analyze their impact on P2P video systems. We also briefly discuss other practical issues in the design of a mobile P2P system for PPTV.
