Internet development and an ever-increasing demand for bandwidth are boosting the market for satellite solutions. Technological progress leading to new satellite capabilities and the availability of bandwidth at lower cost is enabling this growing role of satellites in the Internet world. Satellite solutions are being used for both broadcast/multicast applications and point-to-point services. End-user access combines multicast and point-to-point services while content distribution to the "edge" of the Internet (i.e., to service providers' points-of-presence serving access local loops) is a true multicast application. Geostationary Earth Orbit (GEO) satellites and Low Earth Orbit (LEO) constellations essentially play a complementary role, in order to provide this complete range of services. Due to the large amount of capacity they provide and their low-latency characteristics, LEO systems are very well suited for point-to-point high-quality services while GEO solutions are very efficient for both broadcast/multicast offerings and access services including a significant percentage of multicast data.

Abstract
Internet development and an ever-increasing demand for bandwidth are boosting the market for satellite solutions. Technological progress leading to new satellite capabilities and the availability of bandwidth at lower cost is enabling this growing role of satellites in the Internet world. Satellite solutions are being used for both broadcast/multicast applications and point-to-point services. End-user access combines multicast and point-to-point services while content distribution to the "edge" of the Internet (i.e., to service providers' points-of-presence serving access local loops) is a true multicast application. Geostationary Earth Orbit (GEO) satellites and Low Earth Orbit (LEO) constellations essentially play a complementary role, in order to provide this complete range of services. Due to the large amount of capacity they provide and their low-latency characteristics, LEO systems are very well suited for point-to-point high-quality services while GEO solutions are very efficient for both broadcast/multicast offerings and access services including a significant percentage of multicast data. To support the different services it is important to consider their Quality of Service (QoS) requirements. This Chapter mainly describes QoS requirements for multimedia services based on international standards. Section 3.2 shows a classification of applications according to error and delay tolerance, as well as performance characterization of traditional and multimedia applications. This work is based on the ITU G.1010 [1] standard that has been adopted by other standardization bodies like 3GPP. Section 3.3 presents main QoS support models over IP networks, while Section 3.4 shows main concepts for the transmission of multimedia and broadcast services over satellite networks. Finally, Section 3.5 presents experimental results of application performance over a real platform; the main interest here is to present QoS results on classical and emerging applications. © 2007 Springer Science+Business Media, LLC.
