Video Streaming through Secured CDN based on Demand

Abstract

The hybrid architecture of content distribution network (CDN) and peer to peer (P2P) provides online streaming media services. Simulation makes the study of design  space of hybrid streaming systems more convenient and cost effective . This paper, explains the approach of a designed and discrete event simulator for hybrid CDN-P2P VoD systems. Here the simulator supports multiple switching strategies, different video coding methods and P2P piece selection algorithms. We have verified the simulator and conducted experiments to study the design space of hybrid streaming systems. The results show that adjusting CDN connection threshold would be a more efficient way to provide a smooth streaming than adjusting CDN streaming rate. The simulator will be a reference tool for researchers which would enable them to further look into the hybrid VoD systems.
