    <description descriptionType="Abstract">&lt;p&gt;When designing and deploying multimedia systems, it is essential&amp;nbsp;to accurately know about the necessary requirements and the&amp;nbsp;&lt;br&gt;
Quality of Service (QoS) offered to the customers. This paper&amp;nbsp;presents two open-source software tools that contribute to these&amp;nbsp;&lt;br&gt;
key needs. The first tool is able to measure and register resources&amp;nbsp;consumption metrics for any Windows program (i.e. process id),&lt;br&gt;
like the CPU, GPU and RAM usage. Unlike the Task Manager,&amp;nbsp;which requires manual visual inspection for just a subset of these&amp;nbsp;&lt;br&gt;
metrics, the developed tool runs on top of the Powershell to&amp;nbsp;periodically measure these metrics, calculate statistics, and&amp;nbsp;register them in log files. The second tool is able to measure QoS&amp;nbsp;metrics from DASH streaming sessions by running on top of&amp;nbsp;TShark, if a non-secure HTTP connection is used. For each&amp;nbsp;DASH chunk, the tool registers: the round-trip time from request&amp;nbsp;to download, the number of TCP segments and bytes, the effective&amp;nbsp;bandwidth, the selected&amp;nbsp;DASH representation, and the associated&amp;nbsp;parameters in the MPD (e.g., resolution, bitrate). It also registers&amp;nbsp;the MPD and the total amount of downloaded frames and bytes.&amp;nbsp;The advantage of this second tool is that these metrics can be&amp;nbsp;registered regardless of the player used, even from a device&amp;nbsp;connected to the same network than the DASH player.&lt;/p&gt;</description>
