Abstract In recent years network measurements have been recognized as an area of major interest. There are various software implementations for network measurements, which employ the technique of packet generation. Despite the simplicity and low cost of the software solutions, there are some major drawbacks, like the lack of accuracy, especially at high rates, and the high computational resources requirement leading to the high energy consumption. Therefore in order to have trustworthy results the use of high cost hardware is essential. An alternative solution is to use specialized hardware that incorporates FPGAs that combine high computational capabilities with low energy consumption. One reasonably priced and academic community driven platform is the NetFPGA PCI card. It provides 4 Gigabit Ethernet ports and a powerful FPGA that may be exploited for the development of any network application. Using the NetFPGA platform we developed an affordable, high precision and accuracy multi-gigabit network measurements system, that outperforms any software solution, requires minimum computational capabilities by the host computer and it consumes very low energy. Moreover we have shown the lack of accuracy in the measurements of the popular software solutions, even in low rates, establishing the need of a hardware based solution for reliable results.
