+Our testing scenarios imply sending several files, with different sizes, over
+the network, to different numbers of destinations/peers. Following this, we have
+randomly generated four different files, with sizes varying from 32MB, to 256
+MB. The number of sites was also varying, starting from a single site up to
+eight sites.
+
+Our measurements were done not only between the two virtual machine deployed,
+but also on the loopback interfaces. We considered that the tests would be
+more relevant if they were performed on different machines, because this would
+be the practical use case. However, the results were not different at all, as
+the module algorithm is the same, regardless the device implementation.
+Therefore, in Section \ref{sec:results}, we have only specified the
+measurements we obtained for the tests between the two virtual machines
+deployed.
+
+The only metric we considered in our tests is the time spent on the
+distribution of the file content, from a single peer, to multiple
+destinations. We decided that this is the most relevant metric from the
+application's perspective, as a programmer looks for the best solution
+performance in terms of time spent. Section \ref{sec:results} illustrates the
+test results we have obtained and performs a comparison between the two
+solutions.
