Numerical analysis of the MC scheme and investigation of the effects of its parameters

Abstract

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