A Holistic Approach to Understand HTTP Adaptive Streaming

HTTP adaptive streaming is a demanding application requiring high throughput and low latency, with consumers expecting an ever-increasing quality of experience. This doctoral study proposes a novel methodology to analyze and guarantee these requirements through the establishment of a holistic cross-layer application view. By significantly increasing the amount of data points and sources available as well as combining them into a unified representation, the proposed holistic point of view facilitates root cause analysis. At the same time, it can support or even automate analysis of various (sub)processes in the end-to-end chain. Potential cross-layer optimizations in the workflow are also more easily identified and analyzed.
