We point out that the huge capacity offered by the GPON highlights the enormous differences that can be showed among the available and actually exploitable bandwidth. In fact, while the physical layer capacity can reach value of 100 Mb/s and more, the bandwidth at disposal of the user (i.e. either throughput at transport layer or goodput at application layer) can be much lower when applications and services based on TCP protocol are considered. In the context of Service Level Agreements (SLA) verification, we show how to simultaneously measure throughput and line capacity by offering a method to verify multilayer SLA. We also show how it is possible to better to exploit the physical layer capacity by adopting multiple TCP connections to avoid the bottleneck of a single connection.&lt;/span&gt;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">18</style></issue><section><style face="normal" font="default" size="100%">3357</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Arianna Rufini</style></author><author><style face="normal" font="default" size="100%">Edion Tego</style></author><author><style face="normal" font="default" size="100%">Francesco Matera</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Multilevel QoS vs QoE measurements and Verification of Service Level Agreements</style></title><secondary-title><style face="normal" font="default" size="100%">European Conference on Networks and Communications, EUCNC 2014</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">06/2014</style></date></pub-dates></dates><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Experimental investigation on QoS measurements in terms of throughput versus access capacity, including a correlation in terms of QoE evaluated for some web TV&amp;nbsp;&lt;/p&gt;</style></abstract></record></records></xml>
