Open- and closed-loop traffic regulation schemes for ATM networks

Some new traffic regulation schemes are defined in terms of a relief-spacing (or spacing of the allowance for cell delivery to the network) function. This function may depend only on some user-state, thus defining the class of open-loop relief-spacing traffic regulators; or it may depend on both some user- and network state, thus defining the class of closed-loop relief-spacing traffic regulators. Meaningful criteria for optimizing the performance of both classes are defined. A queueing model is presented to analyze their performance and Markov decision theory approaches are used to identify the optimal elements in the proposed classes
