Several users share a common channel for transmission, which has an average rate constraint. The packets not yet transmitted are queued. The problem of optimal channel allocation to minimize the average sum queue occupancy subject to this constraint splits into individual Markov decision processes (MDPs) coupled through the Lagrange multiplier for the rate constraint. This multiplier can be computed by an on-line stochastic gradient ascent in a centralized or distributed manner. This gives a stochastic dynamic version of Kelly’s decomposition. A learning scheme is also presented.
