Characterizing High-bandwidth Real-time Video Traffic in Residential Broadband Networks

"In this paper, we analyze the results of 24 hour long monitoring and real-time streaming experiments from eight residences with broadband Internet connections.  Using videos encoded with MPEG-4, and using RTP and UDP protocols for streaming, we study the properties of wireless and the end-to-end links in terms of the bandwidth available for streaming, loss and latency that packets experience, and the effect on streaming quality."

 MaxPlanck-160x160 Results of a large-scale measurement study of major cable and DSL providers in North America and Europe.  Characterizes several properties of broadband networks, including link capacities, packet round-trip times and jitter, packet loss rates, queue lengths, and queue drop pollicies -- for network simulation.
