TL;DR: This article identifies invariants in video sharing workloads, through comparison of the workload characteristics of four popular video sharing services, and finds that lifetime popularity measures have some relevance for large cache sizes, but that this relevance substantially decreases as cache size decreases, owing to churn in video popularity.

TL;DR: A large-scale measurement of the most popular peer-to-peer content distribution system, BitTorrent, over eleven months shows that while short-term or small-scale measurements can conclude that the popularity of contents exhibits a power-law tail, the tail is likely exponentially decreasing, especially over long time intervals.

TL;DR: BUFFEST, a novel classification framework that can be used to classify and predict streaming clients' buffer conditions from both HTTP and HTTPS traffic, is presented and results are encouraging and show that BUFFEST can distinguish streaming clients with lowbuffer conditions from clients with significant buffer margin during a session even when HTTPS is used.

TL;DR: This paper introduces the concept of a “multi-video stream bundle” that consists of multiple parallel video streams that are synchronized in time, each providing the video from a different camera capturing the same event or movie.
