In order to provide QoS to some multimedia applications, QoS routing has been studied for a while (but without success). Consider a streaming video application that requires constant bit rate transmission. How do we perform QoS routing for this kind of application? Explain how to defi ne the link cost function, how to compute a path cost from link costs, the granularity of routing decision, the interaction between application protocols and QoS routing.
