OpenFlow-based live video streaming with GENI Cinema

摘要

The use of computer networks to relay streaming multimedia content is on the rise and is expected to continue to increase in the coming years. This paper discusses the use of GENI Cinema as a means to distribute streaming content across different networks at scale. Through the use of OpenFlow, GENI Cinema is able to gain control over the flow and routing of video streams in the network to efficiently and scalably distribute video content from video producers to video consumers. GENI Cinema accomplishes video “channel” switching with minimal perceived delay and no disruption in content to the producers or consumers. A prototype implementation of GENI Cinema on the distributed GENI testbed is discussed.
