IP satellite networks are gaining a considerable interest mainly due
to their ability to deliver high bandwidth services to nation-wide
areas. However some difficulties still exist to implement IP based
transport mechanisms on geostationary satellite networks (i.e. TCP
based protocols are affected by the large delay-bandwidth product).
The satellite network architecture presented in this paper is designed
to provide a complete QoS support for IP traffic based on the DS
paradigm, while minimizing the waste of the valuable satellite resource.
The proposed technique operates on two time scales: a short term
reaction compensates fast traffic variations by an appropriate scheduling
while a medium term resource allocation mechanism reduces the wasted
bandwidth.
