DVS: a system for distribution and management of global video on demand services

The Distributed Video Service (DVS) system provides a comprehensive solution for the management and distribution of global video on demand. DVS presents a scalable architecture that combines the global accessibility of the Internet with an acceptable quality of service through an optional private high-speed backbone, and by distributing movies off-line to servers that are closer to potential viewers. To cope with dynamic changes in movie demand and server load, DVS employs adaptive algorithms for server selection and for movie distribution. DVS was implemented in Java, integrated with a front-end playing software, and supports IP and ATM as the public and private networks, respectively.
