Abstract

Video on Demand is expected to be the first of many Video Dial Tone services that will bring broadband connections to residential customers. While significant research has been undertaken to identify cost effective access architectures, much less effort has been expended on video servers and backbone architectures, and it may be here that competitive advantage can be obtained. This paper focuses on the placement of key architectural elements within the network to show that a network topology which balances centralized and distributed storage of content minimizes backbone costs. Intuitively, storing copies of popular movies close to consumers reduces demand on the network, while centralizing titles reduces the amount of server resources required due to sharing and hence the cost of storage.
