Distributed Client-Assisted Patching for Multicast Video-on-Demand Service in an Enterprise Network

Abstract

Video-on-demand services allow users to select their desired video without watching the broadcast. Videos are stored in distributed servers. A single stream from the server can be utilized to satisfy a batch of common client requests. The key problem of this system is to minimize the server load to satisfy maximum number of clients. We propose a distributed client-side caching technique that reduces the server load significantly and increases the scalability of the system. We have implemented our system and compare our system with another state-of-the-art technique. Experimental results suggest that the newly proposed system outperforms the already proposed client assisted patching scheme.
