Admission power optimization in a window controlled virtual route

The window mechanism has proved to be an easy-to-implement and effective technique for protecting a packet-switched network against congestion. The author proposes a new closed-form rule for window selection. It follows from optimization of the power coefficient which evaluates tradeoffs of an admission process to a window-controlled virtual route. The author slightly modifies Reiser´s (1981) definition of an admission power and shows how this concept makes it possible to match window size to the variable input traffic intensity. The rule subjects window size to a maximum route throughput, which can be easily found by means of the mean value analysis algorithm. Some simulation examples are given
