We report results obtained by an extensive measurement campaign over a live HSDPA network involving more than 3000 flows resulting in around 60 hours of active measurements. The considered TCP variants are the following: | We report results obtained by an extensive measurement campaign over a live HSDPA network involving more than 3000 flows resulting in around 60 hours of active measurements.

We report results obtained by an extensive measurement campaign over a live HSDPA network involving more than 3000 flows resulting in around 60 hours of active measurements. The considered TCP variants are the following:
The experimental evaluation has been carried out by accessing the public Internet using a commercial HSDPA card (see figure below) and by employing the linux Kernel 2.6.24.
The following instantaneous variable measurements have been collected by using the libnetmeas library:
The main findings of the investigation can be summarized as follows:
We report cumulative distribution function plots:
Typical congestion window and RTT evolutions of the considered TCPs in the case of a single flow over the HSDPA downlink
