High Quality VoD Service Architecture on Broadband Internet

摘要

In this paper, for broadband Internet users, high quality VOD (Video on Demand) service architecture including network and platform is presented. As the existing IP-network cannot provide a guaranteed bandwidth, a local server based network architecture is suggested and implemented. Local nodes are established to consider network traffic related to the number of users and geographical locality. Users are routed to the local node that can provide a guaranteed bandwidth. Also VoD service platform is designed to control traffic load balancing, which can distribute traffic load to local servers. The designed load balancing scheme is works well in actual environment. On the service architecture, commercial VoD (Video-on-Demand) service is now open to KT broadband Internet users (http://homemedia.megapass.net).
