Abstract: We develop a unifying framework to perform the end-to-end quality of service (QoS) management of advanced data services in PCS networks. For this purpose, we first describe a generic fluid-flow model with Markov-modulated input flows and variable service rates depending on a Markovian environment for the wireless part of the transport path. Then we indicate how it can be used to evaluate the QoS of the data transport and to what extent the varying capacity of the transport channel influences the latter.
Summary in Swedish: Ett modell som kan modellera den varierande kapaciteten av en trådlös länk beskrivs. Det visas hur hastigheten på ändringarna av kapaciteten påverkar tjänstekvalitén. Flödesmodell, Gilbert-Elliott modell, prestandaberäkningar
