P2P video conferencing system based on WebRTC

Abstract

Cost-effective large-scale real-time video broadcasting technology has remained out of reach despite tremendous efforts and technical innovations over the past two decades. Introduction of Internet Protocol (IP) Multicast and Unicast architecture were earlier attempts to tackle this problem. But serious complications regarding scalability and difficult deployment have dogged these attempts. In recent years peer-to-peer (P2P) based broadcast has emerged as a promising technique because this paradigm brings many unique advantages such as cost-effectiveness, easy deployment, scalability, resilience. While P2P applications such as file download and voice-over-IP have gained much popularity, video conferencing is still in its early stages. The aim of this paper is to introduce P2P VIDEO CONFERENCING SYSTEM BASED ON Web Real Time Communication (WebRTC). WebRTC provides the opportunity of establishing P2P connections within web, without additional plugins and third party software. This paper presents a scalable live video conferencing architecture designed based on WebRTC. Our experiments show that WebRTC is a capable building block for scalable live video conferencing within a web browser.
