Hypo-exponential traffic pattern
The hypo-exponential traffic is also called smooth arrival pattern
and occurs where there is not a great amount of variation in
the traffic. The hold time and inter-arrival time is easily
predictable. Example: a Call-Centre expects 600 calls with a
duration of 2 minutes an hour.

Hyperexponential traffic pattern
The hyperexponential traffic is also called peak arrival pattern.
The variation within a peak arrival pattern is very high. Example
of heavy peak traffic is Christmas day and New Year’s
eve.

Random traffic pattern
The random traffic pattern is also known as Poisson or exponential
distribution. This distribution is generally seen in private
branch exchange (PBX) environment with circuits varying from
1 to 30.
