Performances des applications IP dans les systèmes de communications par satellite : cas du DVB-RCS et du DVB-S2

Abstract : Despite of a number of IP satellite networks developed and deployed, only a limited number of studies and feedbacks about the performance is available. IP over satellite systems raises several constraints. One of the main reasons is the lack of adaptation of IP protocol, initially designed for terrestrial wired networks, to the large bandwidth delay product of the satellite media. Another reason is a lack of coordination between the IP protocol stack upper layer and the satellite MAC and physical layer. The purpose of this PhD study is to evaluate and assess the behaviour of IP applications when conveyed over satellite systems. We mainly focus on the IP quality of service performance, bandwidth encapsulation efficiency as well as IP applications metrics. Through the observation, we try to find how it's possible to modify the IP satellite systems configuration in order to improve IP applications performance. We also suggest some ideas about the way to refine these technologies with regards to the design aspects. Experimentations have been performed over test beds implementing both standardised satellite technologies such as DVB-RCS as well as proprietary systems such as iDirect in addition to the new normalised technology DVB-S2
