Abstract
IP satellite networks are gaining a considerable interest and this
is mainly due to their ability to deliver high bandwidth services
to nation-wide areas. Some difficulties exist, however, to implement
IP based transport mechanisms on geo-stationary satellite networks.
TCP based protocols performance are heavily affected by the large
delay-bandwidth product on GEO satellites and by the coexistence
of UDP and TCP on the same limited resource. In the literature several
methods have been proposed to provide quality of service control
on IP networks. The most scalable approach is the Differentiated
Services (DS). This paper proposes a real-time implementation of
a satellite system, mapping the DS entities on software elements
on a Linux platform. A detailed analysis has been computed to verify
the performance of the RED/DS method with real traffic flows and
some optimization are suggested.
