Chapter 4. Packet-Forwarding Mechanism with Static QoS Mapping


In this work, relative service differentiation that targets a particular ratio of network QoS parameters among service classes is implemented using packet-forwarding mechanisms. However, due to the dynamics of queue lengths (e.g., rapid fluctuation of data traffic), the packet-forwarding mechanisms may not be able to maintain the targeted network QoS ratios during all time windows.

Under the relative DiffServ paradigm, this chapter carries the QoS mapping framework of Chapter 3 further and applies QoS mapping in the queueing system, where the relative differentiated service is implemented through packet-forwarding mechanisms. But, unlike our discussions in Chapter 3, in ...
