Abstract: The issue of QoS (quality of service) provisioning for adaptive multimedia in munication
networks is considered. A reinforcement learning based online adaptive bandwidth allocation optimization
algorithm is proposed. First, an event-driven stochastic switching model is introduced to formulate the adaptive
bandwidth allocation problem as a constrained continuous-time Markov decision problem. Then, an online
optimization algorithm bines policy gradient estimation by learning and stochastic approximation is derived.
This algorithm can online handle the constrained optimization problem efficiently w
