Decentralized Video Streaming Systems

Project Description
Video streaming systems have traditionally been built around the client-server architecture where a video server stores compressed video for delivery to clients connected by a network. With increasing demand for large-scale video streaming services, researchers have spent considerable effort in designing high-capacity video servers. Nevertheless, a video server can only have finite capacity and the continuous server upgrade can become increasingly more expensive as the system scales up.

In this research programme, we investigate a radically different architecture where the bottleneck - video server, is eliminated altogether. This server-less architecture exploits resources in the end-user machines for distributed data storage and video delivery. Thus when new hosts are added to the system, they add resources in addition to workload to the system. This research programme will systematically explore and investigate architectural alternatives for building a scalable, reliable, and cost-effective server-less video streaming system.
