Integrated Resource Management for Geostationary Satellite Networks

This paper describes the resource management protocols and algorithms developed by the University of Rome (UoR) within the GEOCAST project where UoR tasks concern the access layer of a DVB-RCS geostationary satellite network. The functional modules of the access layer have the goal to efficiently exploit the link resources while assuring the contracted Quality of Service to the traffic entering the satellite network. The main novelty is the integration between the Connection Admission Control and the Congestion Control procedures. Both them exploit the estimation of the traffic load, performed by a Kalman filter. The proposed solutions are analyzed via computer simulations, thus confirming their effectiveness.
