A novel and optimal video replication technique for video-on-demand systems

Abstract

With the advances in Information, Networking and Communication technologies, the Multimedia services are gaining high popularity. Especially applications like Video-On-Demand (VoD) systems are becoming inherently popular. VoD is a data-intensive application because clients frequently retrieve data stored on high end servers. As the numbers of users are exponentially growing from thousands to millions severing such large request is a great challenge to the multimedia companies. Hence VoD service providers are intensely interested in high QoS services to users by using efficient algorithms or strategies or architectures. Numerous solutions in terms of algorithms or architectures are available to reduce response times. Among these an efficient techniques for replication, storage and retrieval/streaming has attracted much attention from researchers due to its effectiveness and low cost. This paper focuses on proposing an optimal video replication, storage and retrieval strategies for VoD systems.
