SAT03-1: Loss and Delay QoS Mapping Control for Satellite Systems

An optimization problem for QoS mapping over protocol layers is formalized in this work by taking the ETSI satellite independent-service access point (SI-SAP) as technological reference. The joint optimization of loss and delay performance metrics, together with the presence of SI-SAP QoS mapping operations, introduces the generalization of the regular concept of equivalent bandwidth. This leads to the study of a proper measurement-based control, able to capture the most stringent QoS requirement over time (between loss and delay) and the related instantaneous bandwidth need at the lower layer of the protocol stack. The control methodology is tested through real fading and traffic traces to highlight its effectiveness for real time control of QoS mapping operations.
