Abstract:

Strict priority queueing and weighted round robin are two common scheduling schemes for differentiation of services in telecommunication networks. A combination of these is the priority weighted round robin (PWRR) scheme, which serves three classes of traffic with distinct quality requirements, namely expedited forwarding (EF), assured forwarding (AF) and best effort forwarding (BF). The response time of the AF class is analysed under a worst case scenario and an expression for its mean value is obtained using a queueing model. Numerical results are validated by simulation and implications on service level agreements are discussed.
