We have performed an extensive campaign of measurements that involved around 3000 flows and more than 40 hours of measurements using three different TCP stacks:
The experimental evaluation has been carried out by accessing the public Internet using an UMTS card (see figure below).
The following instantaneous variable measurements have been collected by using the libnetmeas library:
