Multimedia applications such as video conference, digital video broadcasting (DVB), and streaming video and audio have been gaining popularity during last years and the trend has been to allocate these services more and more also on mobile users. The demand of quality of service (QoS) for multimedia raises huge challenges on the network design, not only(More)
End-to-end optimised Quality of Service (QoS) and its specific declination for multimedia applications with the end-user Perceived Quality of Service (PQoS) is nowadays a trendy topic in the literature. Many different techniques and approaches have been proposed, which are in general focusing on specific weak technical aspects of the transmission chain in(More)
— A software platform for demonstration and performance evaluation of network aware joint optimization of wireless video transmission is presented in this paper. This demonstrator has been realized in the framework of the IST PHOENIX project ( and is based on the joint system optimization model developed by the project. After a(More)

— A global approach for realistic network-aware joint source and channel system optimization for wireless video transmission is described in this paper. After a description of the information to be exchanged among the system component blocks, the concept of " JSCC/D controllers " is introduced and the implementation of the first " basic chain " demonstrator(More)
 The Differentiated Services (DiffServ) architecture is a scalable solution for supporting Quality of Service (QoS) in the Internet. The scheduling discipline plays a fundamental role in QoS capable network nodes. The Weighted Fair Queuing (WFQ), has shown many advantages and widely spread in the last years. In this work we present a mechanism for a(More)
Next-Generation Networks (NGNs) employ the Internet Protocol (IP) over a wide variety of packet-switching technologies, which often lack in really effective fault resilience enabling features. An overlay MPLS infrastructure with its fast-reroute mechanisms can be deployed to overcome such an issue. Addressing NGNs robust to single link and node failures, an(More)
In many big cities in the industrialized world, large dedicated data transport networks (the MANs, metropolitan area networks) have been deployed in the last few years to provide cheap broadband Internet access to citizens, as well as broadband interconnections between different branches of a business company. The current MANs are based, in the backbone(More)
