We report an experimental investigation on the
measurement of the available bandwidth for users in Gigabit
Passive Optical Networks (GPON) and the limitations caused by
the Internet protocols. 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 the case of TCP. In this ultrabroadband
environment we also investigated on use of the UDP and of the
multisession TCP. A correlation in terms of QoE is also reported.

This work experimentally demonstrates how to control and manage user Quality of Service (QoS) by acting on the switching on-off of the optical Gigabit Ethernet (GbE) interfaces in a wide area network test bed including routers and GPON accesses. The QoS is monitored at the user location by means of active probes developed in the framework of the FP7 MPLANE project. The network topology is managed according to some current Software Defined Network issues and in particular an Orchestrator checks the user quality, the traffic load in the GbE links and manages the network interface reconfiguration when congestion occurs in some network segments.
