Distributed continuous media streaming - Using redundant hierarchy (RED-Hi) servers

ABSTRACT: The first part of this thesis provides a survey of continuous media serves, including discussions on streaming protocols, models and techniques. In the second part, a novel distributed media streaming system is introduced. In order to manage the traffic in a fault tolerant and effective manner a hierarchical topology, so called redundant hierarchy (RED-Hi) is used. The proposed system works in three steps, namely, object location, path reservation and object delivery. Simulations are used to show that the scheme, proposed here, performs better than the traditionally used multimedia transmission models in terms of various parameters. Results show that this scheme gives better transmission rates and much lower blocking rates. Furthermore it exhibits higher fault tolerance and greater load balancing of the streaming tasks among the servers of the streaming system.
