Multicast adaptive logic for Dynamic Adaptive Streaming over HTTP network

摘要

Video streaming constitutes the vast majority of Internet traffic and the DASH protocol has become the de-facto standard in the industry of multimedia delivery. The multicast method for information distribution has the potential to dramatically reduce multimedia streaming traffic; however, to date, there is no effective Adaptive Logic (AL) designed to support multicast constraints at the client side. In this paper we present an adaptive logic that is designed specifically for multicast scenarios. A comparison of our Multicast Adaptive Logic (MAL) with leading ALs under multicast conditions demonstrates that MAL provides the best performance under multicast conditions and good performance under unicast conditions.
