Role of queue length information in congestion control and resource pricing

Research output: Contribution to journalArticle


We consider a single-user congestion problem with a packet loss constraint viewed as a stochastic control problem. Using a precise nonlinear model of the queue with time-varying Markovian service rate, we show that the optimal controller is a bang-bang type solution. Additionally, we show that the stochastic problem with the Quality-of-Service (QoS) constraint can also be viewed as an unconstrained stochastic problem where the user is forced to pay a price for QoS violations.
