A DVB/IP QoS aware Backhaul Networking Environment

The paper discusses a DVB/IP backhaul networking environment that enables users to access triple-play IP services at a guaranteed end-to-end QoS level. Utilising the DVB-T stream in a regenerative configuration, it presents the formation of a QoS aware backhaul that interconnects intermediate distribution nodes and service/content providers (e.g. ISPs, IPTV multicasters, etc.), for enabling always-on and triple-play services access, even from rural or dispersed areas. The capability of the proposed QoS aware DVB/IP backhaul networking environment is validated through experimental tests, that were conducted under real transmission/reception conditions at a prototype infrastructure that conforms to the discussed architectural design issues.
