An Erlang is a unit of telecommunications traffic measurement Strictly an Erlang represents the continuous use of one voice path In practice it is used to describe the total traffic volume of one hour For example if a group of user made 30 calls in one hour and each call had an average call duration of 5 minutes then the traffic figure is worked out as follows Minutes.

Agner Krarup AK Erlang was a Danish pioneer of the study of telecommunications traffic in the early s A comprehension of Erlang calculation and traffic measurements make it much easier for telecom network designers to manage traffic patterns in their voice networks as well as call center managers to staff agnee centers.
