P2P media streaming with HTML5 and WebRTC

Video-on-demand (VoD) services, such as YouTube, generate most of the Internet traffic today, and the popularity of video services is growing. Service and CDN providers have to invest more and more in distribution networks, which creates pressure to innovate novel approaches. Peer-to-peer (P2P) streaming is a viable alternative that is scalable and can meet the increasing demand. The emerging HTML5 standard introduces APIs that give web browsers an ability to communicate directly with each other in real time. New standards also enable a setup, where browsers can act as P2P nodes. This paper reviews whether the new HTML5 and WebRTC standards are a fit for P2P video streaming, evaluates the performance challenges and proposes solutions. Preliminary analysis indicates that HTML5 can be applied to VoD, but there are concerns.
