Abstract 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.
