Analysis and implementation of the Large Scale Video-on-Demand System
This addresses economic and design constraints for deploying VOD systems in Next Generation Networks, though it appears incremental in methodology.
This paper tackles the problem of efficiently planning large-scale Video-on-Demand (VOD) systems by analyzing network bandwidth requirements for centralized server and distributed local proxy architectures, developing traffic models to evaluate operational needs.
Next Generation Network (NGN) provides multimedia services over broadband based networks, which supports high definition TV (HDTV), and DVD quality video-on-demand content. The video services are thus seen as merging mainly three areas such as computing, communication, and broadcasting. It has numerous advantages and more exploration for the large-scale deployment of video-on-demand system is still needed. This is due to its economic and design constraints. It's need significant initial investments for full service provision. This paper presents different estimation for the different topologies and it require efficient planning for a VOD system network. The methodology investigates the network bandwidth requirements of a VOD system based on centralized servers, and distributed local proxies. Network traffic models are developed to evaluate the VOD system's operational bandwidth requirements for these two network architectures. This paper present an efficient estimation of the of the bandwidth requirement for the different architectures.
