Vídeos Gerados por Usuários: Caracterização de Tráfego

Marcelo A. MaiaVirgílio AlmeidaJussara Almeida

The growth of Internet traffic derived from the user generated videos motivated this work. We seek to understand characteristics of users and videos from four online video sharing systems. We focus on traffic origin and temporal evolution of both recently added and already popular videos. The most recent videos experience on average a number of requests on their first days comparable to some of the most popular videos, indicating that these recent videos are potential candidates to be served from cache. We propose a two-level caching strategy that exploits both popularity and recency to reduce request traffic.
