A Novel QoS Architecture for Next Generation Broadband Satellite Systems

This paper presents the architecture developed in Satsix project in order to improve the current QoS level in satellite/terrestrial networks. The dynamic QoS support is one of the major achievement of SATSIX in the QoS area, with the extension of the QoS agent/server architecture proposed in the previous SATIP6 project. This QoS architecture is based on DiffServ architecture, and it has been proposed aiming to tackle different QoS level sessions.
