QoE and QoS comparison in an anycast digital television platform operating on passive optical network

We report an experimental investigation on QoE, compared with the QoS, for a complete digital television platform able to deliver broadcast, multicast and unicast services in wide geographical area network, with broadband access based on passive optical network (PON). In particular, we show the service degradation due both to network impairments and to the TCP limits on operating systems. Multicast forwarding was tested in PBB-TE environment to exploit a Carrier Ethernet behavior. Concerning broadcasting, such a network allows the user to see the DVB-T by using the same optical infrastructure by means of the specific wavelength foreseen by the GPON standard.
