We report an experimental investigation on the
measurement of the available bandwidth for users in Gigabit
Passive Optical Networks (GPON) and the limitations caused by
the Internet protocols. We point out that the huge capacity
offered by the GPON highlights the enormous differences that
can be showed among the available and actually exploitable
bandwidth in the case of TCP. In this ultrabroadband
environment we also investigated on use of the UDP and of the
multisession TCP. A correlation in terms of QoE is also reported.

Taking advantage oftwo week-long data sets separated in time by 10 months and reporting the web activity of more than 10,000 ADSL residential customers, we identify the services offered by large organizations like Google, Akamai and Amazon.

Results depict anovercrowded scenario in constant evolution. Big-players are more and more responsible for the majority of the volume and a plethora of other organizations offering similar or more specific services through different CDNs and traffic policies. Unfortunately, no standard tools and methodologies are available to capture and expose the hidden properties of this in constant evolution picture. A deeper understanding of such dynamics is however fundamental to improve the performance of current and future Internet. To this extend, we claim the need for a Internet-wide, standard, flexible and intelligent measurement plane to be added tothe current Internet infrastructure.}, keywords = {Facebook, Google, Monitoring, Organizations, Servers, Streaming media, Throughput}, issn = {978-1-4673-1390-2}, doi = {http://dx.doi.org/10.1109/NETWKS.2012.6381662}, author = {Alessandro Finamore and Vinicius Gehlen and Marco Mellia and Maurizio M Munafo{\textquoteright}} }
