“…This case might happen as well with the MAC protocols proposed in [13,19,20]. Other algorithms based on the QoS information provided by the xQoS-Interpreter, could be implemented within the MAC protocols proposed in these papers, taking then advantage of the real time vision of flow and ADUs requirements.…”

“…RBDC is then well adapted to VBR traffic, because, due to frequent requests, a fast adaptation to bandwidth changes is possible. Besides, the measurement of input traffic is long enough (500 ms) to avoid requesting instantaneous rate variations of the video stream that is not representative of the real requirement of the flow for a longer period, as stated in [12] and in [13]. A sustained traffic will be doing periodical requests thus avoiding timers expiration that would imply additional delays.…”

“…Other algorithms based on the QoS information provided by the xQoS-Interpreter, could be implemented within the MAC protocols proposed in these papers, taking then advantage of the real time vision of flow and ADUs requirements. For instance, if using the combined RA/DAMA access scheme proposed in [13], the xQoS-Interpreter could be used to differentiate important information of the video stream, that should be sent using the granted resource (the DAMA technique), from less important information that could be sent using Random Access technique, more prone to loss.…”

The need for on-demand QoS support for communications over satellite is of primary importance for distributed multimedia applications. This is particularly true for the return link which is often a bottleneck due to the large set of end-users accessing a very limited uplink resource. Facing this need, Demand Assignment Multiple Access (DAMA) is a classical technique that allows satellite operators to offer various types of services, while managing the resources of the satellite system efficiently. Tackling the quality degradation and delay accumulation issues that can result from the use of these techniques, this paper proposes an instantiation of the Application Layer Framing (ALF) approach, using a crosslayer interpreter (xQoS-Interpreter). The information provided by this interpreter is used to manage the resource provided to a terminal by the satellite system in order to improve the quality of multimedia presentations from the end user's point of view. Several experiments are carried out for different loads on the return link. Their impact on QoS is measured through different application as well as network level metrics.

Recent advances in Random Access (RA), improving throughput and loss rates, make the usage of such technique particularly interesting to complement Demand Assigned Multiple Access (DAMA) channels for the return link of satellite systems. In this paper, a novel approach for the integration of the two access strategies aimed at transmission delay optimization is presented. An algorithm for DAMA and RA delay estimation is presented, and its accuracy shown by simulations. Furthermore, the benefits of the proposed integration concept are demonstrated with significant gains in delay and throughput in moderate to high load operating regions.

Using traffic prediction and estimation of provider revenue for a joint GEO satellite MAC/CAC scheme

Satellite networks present an attractive solution in providing worldwide access to the present and future generation multimedia communication services. However, the burstiness of multimedia traffic and the long propagation delays in Geostationary (GEO) satellite systems call for an efficient Medium Access Control (MAC) protocol and an equally efficient Call Admission Control (CAC) scheme, in order to provide acceptable Quality of Service (QoS) to multimedia users. This paper proposes a fair and dynamic CAC and MAC framework, named Fair Predictive Resource Reservation Access (FPRRA), which is based on accurate videoconference traffic prediction and makes decisions after taking into account the provider revenue. The framework's performance is evaluated in comparison to other efficient schemes from the literature.
