A Control-Theoretic Approach for Dynamic Adaptive Video Streaming over HTTP research paper

give me following questions answers

1) What problem is it solving? 2) Why is that problem important? 3) What was the previous state of the art? 4) How (and how much) does this paper advance the state of the art? 5) How does the protocol, system, or design work? 6) What are the key insights in the design that enabled it to advance the state of the art? 7) How is the design evaluated and what are the key results? 8) What related problems are still open and is this problem fully solved?

Follow-On Research: ------------------- What would your follow-on research to this paper be? For example, improve an algorithm in the paper. Include a rough evaluation (see below). This is the category you will almost always naturally fall into when reading a paper! Virtually reimplementing the work based on the problem and goals will almost always lead to a good one of these!

Generalizer / Specializer: -------------------------- Can you generalize what the paper is doing so your sketch of a design can do a strict superset of what the paper does, while still being mostly as efficient? Or, can you specialize what the paper is doing so your sketch of a design can do a strict subset of what the paper does, but does it more efficiently?

(Explain why it's a specialization/generalization, explain why we care about it, explain how your design would differ for it, explain what your design would do better, and explain why specifically it would realize that improvement). Include a rough evaluation (see below).
