Rate control optimization for bandwidth provision over satellite independent service access points

The quality of service (QoS) provision requires the cooperation of all network layers from bottom-to-top. More specifically, in the ETSI broadband satellite multimedia architecture, the physical layers are isolated from the rest by a satellite independent-service access point (SI-SAP). The structure of SI-SAP protocol model "opens the door" to the problem of mapping the performance requests of satellite independent (SI) layers over (SD) satellite dependent technology. In this perspective, we investigate here a novel control algorithm for QoS mapping at the SI-SAP interface. Through the adoption of infinitesimal perturbation analysis, we are able to capture the "bandwidth need" of the different flows when they are conveyed to the SD core. Simulation results validate the proposed approach
