A Hybrid of Adaptation and Dynamic Routing based on SDN for Improving QoE in HTTP Adaptive VBR Video Streaming
Recently, HTTP Adaptive Streaming HAS has received significant attention from
both industry and academia based on its ability to enhancing media streaming
services over the Internet. Recent research solutions that have tried to
improve HAS by adaptation at the client side only may not be completely
effective without interacting with routing decisions in the upper layers. In
this paper, we address the aforementioned issue by proposing a dynamic
bandwidth allocation and management architecture for streaming video flows to
improve users satisfaction. We also introduce an initial cross layer hybrid
method that combines quality adaptation of variable bitrate video streaming
over the HTTP protocol at the client side and SDN based dynamical routing. This
scheme is enabled by the Software Defined Networking architecture that is now
being considered as an emerging paradigm that disassociates the forwarding
process from the routing process. SDN brings flexibility and the ability to
flexibly change routing solutions, in turn resulting in dynamically improving
the services provided in the application layer. Our experimental results show
that the proposed solution offers significantly higher overall bitrates as well
as smoother viewing experience than existing methods.Comment: 14 pages, 17 figures, IJCSNS International Journal of Computer
