A probability theory that expresses the probability of events occurring in a fixed period of time if each event is independent of the previous event. In traffic engineering, that theory means Drops Bridge Headend Point-to-Point Point-to-Multipoint that each call is completely independent of any previous call.There are a number of other techniques based on other assumptions underlying other formulas that yield different results.
