CloudTCast: A Video Distribution Solution Based on Cloud and Tree-based ALM

Abstract

This paper studies a novel data distribution solution, named CloudTCast, for video multicast group. CloudTCast combines the advantages of cloud and tree-based application layer multicast (ALM). On the one hand, it uses the tree-based ALM to break the cloud's bandwidth limitation in delivering the video to large-scale concurrent users. On the other hand, it leverages cloud to effectively improve the performance of tree-based ALM. CloudTCast can make elastic extension in terms of the size of specific video multicast group.
