Paper Abstract
Web services such as YouTube which allow the distribution of user-produced media have recently become very
popular. YouTube-like services are different from existing traditional VoD services because the service provider
has only limited control over the creation of new content. We analyze how the content distribution in YouTube
is realized and then conduct a measurement study of YouTube traffic in a large university campus network. The
analysis of the traffic shows that: (1) No strong correlation is observed between global and local popularity; (2)
neither time scale nor user population has an impact on the local popularity distribution; (3) video clips of local
interest have a high local popularity. Using our measurement data to drive trace-driven simulations, we also
demonstrate the implications of alternative distribution infrastructures on the performance of a YouTube-like
VoD service. The results of these simulations show that client-based local caching, P2P-based distribution, and
proxy caching can reduce network traffic significantly and allow faster access to video clips.
