NUMERICAL-ANALYSIS OF THE MC-SCHEME AND INVESTIGATION OF THE EFFECTS OF ITS PARAMETERS

ATM (Asynchronous Transfer Mode) has been standardized by ITU-T, in or der to realize the broadband ISDN. Due to its properties, such as pack et-oriented information transfer without flow control and flexible all ocation of transmission capacity. in order to ensure quality of servic e for all existing calls, it is necessary to monitor and regulate the traffic for each call based on traffic descriptor. This kind of contro l is done by a policing function. There are many proposed policing sch eme;. Among them, the MC (Moving Ceiling) scheme is considered as an e fficient mean cell rate policing scheme. It has been recently proposed and proved to have a promising performance in mean cell rate enforcem ent by simulation. In this paper. we formulate numerical equations to calculate the steady state probability and output rate of the MC schem e. And using them, we investigate the effects of MC parameters on its performance.
