NFV-Based Mobile Edge Computing for Lowering Latency of 4K Video Streaming.

Ultra-high quality video streaming is expected to be the standard for multimedia in the next decade. However, it poses many problems with the current internet transmission technologies, such as network latency, stalling while a video is playing back. Researchers and network operators have spent much attention on solving such problems such as the latest video compression technique using for 4K and 8K video. In this article, we present another approach to improving ultra-high quality video streaming over the internet mainly focusing on mobile edge computing (MEC). Specifically, we propose an NFV-based MEC to transmit ultra-high quality multimedia efficiently. Besides, our proposed streaming system is dynamic adaptive streaming which supports streaming seamlessly with bandwidth fluctuation. As a result, our system provides 4K and 8K video streaming efficiently with lower latency up to 10% compared to existing approaches.
