LEVELS OF TRAFFIC BEHAVIOUR So, what kind of traffic behaviour are we interested in for ATM, or IP? In Chapter 3 we looked at the flow of calls in a circuit-switched telephony network, and in Chapter 4 we extended this to consider the flow of cells through an ATM buffer. In both cases, the time between ‘arrivals’ (whether calls or cells) was given by a negative exponential distribution: that is to say, arrivals formed a Poisson process. But although the same source model is used, different types of
