연결 수락 제어를 갖는 입력 대기행렬 ATM 교환기의 성능 분석

초록

This paper analyzes the call admission control (CAC) effects on the input queueing ATM switch by using the Markov chain model. The arrival process is modeled as a discrete-time Markov modulated Bemoulli process (MMBP) driven from call states in input and output ports. We analyze the virtual queue which consists of the cells waiting at the HOL position in each input port, and evaluate input queue using the virtual queue analysis results. With these result, we obtain the cell delay and the loss probability as performance measures. We verify the analysis results through computer simulation. Finally, we discuss the effects of the correlated traffic parameters on the system performance.
