“…Then, the results are forwarded to ServMon@NP, which evaluates the satisfaction of service agreements crossing its domain and sends a report along the return path to the ServMon@SP that initiated the current monitoring procedure. A customer service violation is reported if PQoS falls below a certain threshold, as defined within the related service agreement and then a PQoS alert with related NQoS is sent to the AM for deciding a new adaptation (MPEG-21 Digital Item Adaptation, DIA, references in [1], [2]). The perceptual degradation of the initial video content across the content generation, distribution and consumption chain sets novel research perspectives.…”

The media content provision in a variety of quality and price levels, through the concept of the Perceived Quality of Service (PQoS) is considered as the most dominant among the various future visions of multimedia networking. The concept of the PQoS-driven service provision, based on multimedia content adaptation across heterogeneous networks, will become in the near future a key-issue among service providers (SPs). This paper presents, describes and proposes a novel cross layer monitoring architecture, driven by a prototype mapping between Network QoS (NQoS) and PQoS parameters, aiming at providing perceived performance verification with respect to the QoS guarantees specified in contractual agreements between providers and end-users. Towards this, the proposed framework takes sophisticated actions for real time media content adaption with aim the optimization of the finally delivered perceptual quality and the maximization of the user experience. The validity of the proposed model is tested by a real test-bed, demonstrating satisfactory accuracy of the network measurements and the overall feasibility of the proposed monitoring solution.

“…Typically, several solutions [2,10,18] propose the adaptation of the application, forward error correction (FEC) and/or medium access control (MAC) automatic repeat request (ARQ). Going beyond in terms of management solutions definition but also in implementation validation, different research projects such as ENTHRONE [27] or more recently SEA [30] have introduced respectively system management solutions or adaptation procedure to deal with end-to-end QoS improvement and wireless adaptation. These various solutions and many others in the literature are definitely proposing improvements and better quality of service for the end-user.…”

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 the considered scenario. The end-toend optimisation of a complete system system is however more complex and its practical realisation remains to be achieved, especially with the added constraint to be transparently integrated in existing legacy systems so as to not perturbate their current modes of operation. In this paper, we propose an architecture set-up within This work has been carried thanks to INFSO-ICT-214625 OPTIMIX project, which is partially funded by the European Commission within the EU 7th Framework Programme and Keywords End-to-end optimisation • High fidelity simulation • Quality of Service • Joint source channel (de)coding • Multimedia transmission • Point to multi-point video delivery • Cross-layer design • IPv6 mobility • Adaptive medium access control

“…This processing is computationally cheap and can even be performed by off-the-shelf network devices [22]. The gBSD-based adaptation was used as a basis for our work since it was already intensively evaluated and deployed as part of various EC-funded projects (DANAE [7,19], ENTHRONE [9,41]). …”

This paper presents a cross-layer modelformulated using interoperable description formats-for the adaptation of scalable H.264/MPEG-4 AVC (i.e., SVC) content in a video streaming system operating on a Wireless LAN access network without QoS mechanisms. SVC content adaptation on the server takes place on the application layer using an adaptation process compliant with the MPEG-21 Digital Item Adaptation (DIA) standard, based on input comprised of MPEG-21 DIA descriptions of content and usage environment parameters. The latter descriptions integrate information from different layers, e.g., device characteristics and packet loss rate, in an attempt to increase the interoperability of this cross-layer model, thus making it applicable to other models. For the sake of deriving model parameters, performance measurements from two wireless access point models were taken in account. Throughout the investigation it emerged that the behavior of the system strongly depends on the access point. Therefore, we investigated the use of endto-end-based rate control algorithms for steering the content adaptation. Simulations of rate adaptation algorithms were subsequently performed, leading to the conclusion that a TFRC-based adaptation technique (TCP-Friendly Rate Control) performs quite well in adapting to limited bandwidth and varying network conditions. In the paper we demonstrate how TFRC-based content adaptation can be realized using MPEG-21 tools.
