Abstract

Adaptive streaming dynamically adapts video quality level according to the perceived device status and network conditions. It requires several representations of the same content, each encoded at different quality rates. As a representative example, H.264/SVC eliminates the requirement of redundant representations, improving the efficiency of caching and storage infrastructure. SVC video consists of a "Base Layer" and one or more of "Enhancement Layers". These layers have inter-dependencies and different QoS requirements. On another side, SDN allows forwarding tables to be adjusted dynamically, enabling us to route every individual flow differently. In this paper, we propose ELBA, an algorithm for scalable video streaming over SDN. ELBA utilizes the dynamic re-routing capability of SDN, to stream different layers of SVC coded video over possibly different suitable paths. In the proposed video streaming system, we use a novel mechanism to exchange information between the control plane and streaming servers. We have compared the performance of our approach with traditional Internet routing technique. Our evaluation results show that our proposal is not only feasible but in particular, it significantly outperforms the traditional Internet routing approach in terms of QoE.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
