Our experiments include the following cases: (i)~two nodes with saturated queues, sending fixed-length UDP packets to each other, and (ii)~a TCP-controlled transfer between two nodes. Our experiments are based entirely on Aruba \mbox{AP-70} access points operating under Linux. We report our observations on certain non-standard behavior of the devices. In cases where the devices adhere to the standards, we find that the results from the analytical models estimate the experimental data with a mean error of 3-5\%.} }
