TL;DR: In this article, the authors analyzed YouTube, the world's largest UGC VoD system, and provided an in-depth study of the popularity life cycle of videos, intrinsic statistical properties of requests and their relationship with video age, and the level of content aliasing or of illegal content.
Network coding for large scale content distribution
Christos Gkantsidis,Pablo Rodriguez +1 more
- 13 Mar 2005
TL;DR: It is demonstrated through simulations of scenarios of practical interest that the expected file download time improves by more than 20-30% with network coding compared to coding at the server only and, byMore than 2-3 times compared to sending unencoded information.
Analyzing the video popularity characteristics of large-scale user generated content systems
TL;DR: This paper empirically shows how UGC services are fundamentally different from traditional VoD services, and analyzes the intrinsic statistical properties of UGC popularity distributions, which discuss opportunities to leverage the latent demand for niche videos (or the so-called "the Long Tail" potential).

TL;DR: This paper designed, implemented, and validated NetStitcher, a system that employs a network of storage nodes to stitch together unutilized bandwidth, whenever and wherever it exists, and demonstrates that the solution can perform large data transfers at a much lower cost than naive end-to-end or store-and-forward schemes.
