This paper looks at P2P traffic over bittorrent from a large database
of torrents. The paper considers the effects of localising bittorrent
traffic on performance and ISP cost saving.
Data: The data set is one of the impressive things about this paper.
100K torrents of which 40K active. Demographics from 3.9M
concurrent users and 21M total users over a day from 11K ISPs.
Speed test results from ookla and iplane.
This paper looks at ways of predicting the TCP throughput of a connection.
The assumption is that some information is available about the connection.
A comparison is made between “formula based” (FB) prediction, that is using
round-trip time and loss versus time series analysis prediction (referred to
here as history based (HB)), that is
using previous measurements on the same connection. Both approaches
require some measurements from the connection already.
Talk to Next Generation Networks meeting -- this talk is partly based on the ICC paper (fundamental relationships in TCP flows) and shows how TCP throughput arises from network parameters and engineering decisions.
