Deliverable D4.2 - Final system test report

The 6QM Consortium identified several important kinds of tests to be performed on its prototype. Each one is needed to know different aspects of the accuracy on the most important parameters of the OpenIMP system, mainly the packet loss and precision of the measured one-way-delay. The evaluation of those two parameters is enough because all the calculations made by the OpenIMP system are based on them, so no extra tests are required.

The tests have been performed on laboratory not only to know the reliability of such parameter but also, and maybe the most important, how different aspects like type of CPU, RAM amount on the system, number of measurement tasks running on the probes, etc. can influence on precision of the obtained results. As secondary objective, it was stated interesting to find out the limit traffic rate that the each architecture can support with reliable information. Regarding this point, it has been proved that 6QM probes installed on PIV 2.8 GHz are enough to capture packet on OC3 interface in a reliable way. The description of the tests, result and conclusions are presented on this deliverable.
