## poisson distribution - Computer Definition

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.

A statistical method developed by the 18th century French mathematician S. D. Poisson, which is used for predicting the probable distribution of a series of events. For example, when the average transaction volume in a communications system can be estimated, Poisson distribution is used to determine the probable minimum and maximum number of transactions that can occur within a given time period.
