A tandem queueing network with feedback admission control


Admission control in queueing networks is often based on partial information on the network state. This paper studies how the lack of state information affects performance by considering a simple model for admission control. The model is analyzed by studying a related censored process that has a matrix-geometric steady-state distribution. Numerical results show how partial information may cause some performance characteristics in queueing networks to be nonmonotone with respect to service rates.


Key words: queueing network, admission control, feedback signaling, censoring
