A New Grid Architecture Using JMF for Video-On-Demand Applications

Free registration required

Executive Summary

Grid computing was used only in scientific laboratories for many years. Only during the last few years, it is evolving into a business-innovating technology that is driving commercial adoption. In this paper, a Grid-based multimedia application for the distributed tailoring and streaming of media files is proposed. An innovative multimedia data dissemination strategy, based on the Fibonacci series, is used. To respond to the Quality-of-Service (QoS) requirements, soft real-time applications, a new architecture is presented. Such architecture is able to manage the Grid resource allocation effectively. Technical and practical problems encountered during the development are discussed, and a thorough performance evaluation of the developed prototype is presented. The developed application is found to be better than the existing architectures.
