P2P Media Streaming with HTML5 and WebRTC

Abstract-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

A Survey on Adaptive Multimedia Streaming

Internet was primarily designed for one to one applications like electronic mail, reliable file transfer etc. However, the technological growth in both hardware and software industry have written in unprecedented success story of the growth of Internet and have paved the paths of modern digital evolution. In today’s world, the internet has become the way of life and has penetrated in its every domain. It is nearly impossible to list the applications which make use of internet in this era however, all these applications are data intensive and data may be textual, audio or visual requiring improved techniques to deal with these. Multimedia applications are one of them and have witnessed unprecedented growth in last few years. A predominance of that is by virtue of different video streaming applications in daily life like games, education, entertainment, security etc. Due to the huge demand of multimedia applications, heterogeneity of demands and limited resource availability there is a dire need of adaptive multimedia streaming. This chapter provides the detail discussion over different adaptive multimedia streaming mechanism over peer to peer network

LiveShift: mesh-pull P2P live and time-shifted video streaming

The popularity of video sharing over the Internet has increased significantly. High traffic generated by such applications at the source can be better distributed using a peer-to-peer overlay. LiveShift combines both live and on-demand video streaming -- while video is transmitted through the peer-to-peer network in a live fashion, all peers participate in distributed storage. This adds the ability to replay time-shifted streams from other peers in a distributed and scalable manner. This technical report describes an architecture, a mesh-pull protocol, and a set of policies that support the envisioned use case enable. User-focused evaluation results show its effectiveness and limits in terms of quality of experience

The Design and Deployment of a BitTorrent Live Video Streaming Solution

Abstract—The BitTorrent protocol is by far the most popular protocol for offline peer-to-peer video distribution on the Internet. BitTorrent has previously been extended to support the streaming of recorded video, that is, Video-on-Demand (VoD). In this paper, we take this support for video streaming a step further by presenting extensions to BitTorrent for supporting live video streaming, which we have implemented in our BitTorrent client called Tribler. We have tested our extensions both by running simulations, and by deploying our implementation in a public trial in the Internet, using the optimal values of several parameters as found in the simulations. We analyse the performance of Tribler in systems with varying values for the percentage of peers behind a firewall or NAT, which we consider to be one of the key parameters in the performance of deployed P2P systems. Our public trial lasted 9 days, during which 4555 unique peers participated from around the globe. We found 61 % of the peers to be behind a firewall, a level at which our simulations still indicate acceptable performance. Most of the peers indeed obtained good performance, with for instance a very low prebuffering time before playback starts, indicating the feasibility of our approach. The median prebuffering time we measured was 3.6 seconds, which is 3–10 times shorter than the prebuffering time measured in other deployed peer-to-peer systems. I

Recent Trends in Communication Networks

In recent years there has been many developments in communication technology. This has greatly enhanced the computing power of small handheld resource-constrained mobile devices. Different generations of communication technology have evolved. This had led to new research for communication of large volumes of data in different transmission media and the design of different communication protocols. Another direction of research concerns the secure and error-free communication between the sender and receiver despite the risk of the presence of an eavesdropper. For the communication requirement of a huge amount of multimedia streaming data, a lot of research has been carried out in the design of proper overlay networks. The book addresses new research techniques that have evolved to handle these challenges
