A Petri net model of individual traffic source is presented. It is noted that the current set of traffic parameters recommended by ATM-forum is not enough to synthesize optimal traffic control system. The feature of traffic self-similarity can be used to effectively solve optimal control task. An example of an optimal control scheme for cell discarding algorithm is presented.16 pages, postscript file, pre-final version to appear in IEEE INFOCOM'98 The Conference on Computer CommunicationsAdaptation and Self-Organizing Systemstext
