Determination of Save Operating Border of Asynchronous Data Traffic Based on MMPP

This paper reveals an analytical method of evaluating performance of an asynchronous transfer mode (ATM) data link based on the chain of two states Markov Modulated Poisson Process (MMPP). Two important traffic parameters, ‘successful retransmission time’ and ‘average system failure time’ of packet are considered as the key factors for evaluation of save operating region of a network. A group of curves for the above two parameters are drawn against probability of single bit error, taking ‘threshold erroneous bit’ as a parameter. The trajectory of intersection points of the above set of curves is determined to observe the profile of the border of safe operating region of the ATM link.
