BRAHMS aims at specifying an IPbased architecture for broadband satellite access independently of the particular satellite technology adopted in the satellite link. Its goal is to promote integration and harmonization of many access network services and functions, whilst allowing flexibility for optimized or proprietary air interfaces This objective is achieved by supporting a choice of several RTD (Radio Technology Dependent) access technologies through a common set of RTI (Radio Technology Independent) protocols.

The proposed mechanism is in charge of dynamically partitioning the uplink capacity among the connections in progress in the considered spot-beam. Such a partitioning is performed aiming to match the QoS requirements of each connection and to maximize bandwidth exploitation. A Control Theory approach is adopted to address the problem of the delay between the bandwidth request and bandwidth assignment, and the signaling overhead caused by control messages.

In that respect, it discusses modelling issues related to access network technologies, to the core network, and to traffic generation. Furthermore, the implementation of the simulator within the ns-2 framework is described, and preliminary simulation results are reported, showing how the lack of QoS mechanisms in one segment of the network negatively affects the overall performance..

This task is performed sharing dynamically, each signalling time, the resources available among the requiring users services, avoiding congestion states and guaranteeing an agreed Quality of Service. The proposed algorithm is fully compliant with the DVB-RCS standard, but due to its independence from the network technology it can be easily adopted in CDMA systems.
