چکیده
The standardization of a Return Channel via Satellite and the satellite community efforts in term of interoperability over the last few years stands for major milestones in the development of reliable, efficient and low cost satellite equipments. It leads to quite a positive outcome: geostationary satellite networks are expected to play a decisive role in bridging the existing digital divide through providing broadband access to multimedia services in low terrestrial infrastructure areas. However, unlike cable or 3GPP access networks, a lot of work on IP over satellite has been needed, especially about Quality of Service (QoS). The QoS architecture takes benefits from DVB-RCS dynamic allocation schemes and IP QoS architecture to cope with the satellite delay and the scarce uplink resources. This chapter deals with design and evaluation of Quality of Service Architecture to be implemented in DVB-S2/RCS systems.

Resources Management using Adaptive Fade Mitigation Techniques in DVB-S2/RCS Multi-Beam Systems
[Abstract] A powerful and flexible software radio resource management (RRM) simulator suited for modelling a realistic Ka-band multi-beam DVB-S2/RCS system with European coverage is described. The simulator enables design, optimisation and trade-off of RRM techniques that are suitable for the DVB-S2 and an enhanced adaptive DVB-RCS standards which allow efficiently counteracting the link qualit...
متن کاملPerformance Assessment Using Acm in Dvb-s2/advanced Dvb-rcs Satellite Systems
This paper presents the benefits of using adaptive coding and modulation in DVB-S2/advanced DVB-RCS satellite systems. The results are based on a satellite system simulator which was developed during an ESA study. Such a simulator aims at making performance assessments before implementing a system, at developing and evaluating new algorithms like schedulers, encapsulators or resource managers. ...

The main added value of the European Telecommunications Standards Institute broadband satellite multimedia (ETSI BSM) architecture is the definition of the Satellite Independent-Service Access Point (SI-SAP) protocol interface, which formally separates Satellite Dependent (SD) from SI layers, thus enabling the implementation of powerful vertical QoS mapping strategies. On the other hand, DVB-S2...

متن کاملQoS Architecture over DVB-RCS satellite networks in a NGN framework
Geostationary satellite networks are currently considered as one of the most promising broadband access network technology for narrowing the digital divide. Though technically attractive and cost effective, the provisioning of endto-end QoS services in satellite access remains largely undefined. In order to bridge this gap, the European SATIP6 project defines a complete QoS architecture involvi...
