Network traffic ordata traffic is the amount ofdata moving across anetwork at a given point of time.[1] Network data incomputer networks is mostly encapsulated innetwork packets, which provide the load in the network. Network traffic is the main component for network traffic measurement, network traffic control and simulation.
Proper analysis of network traffic provides the organization with thenetwork security as a benefit - unusual amount of traffic in a network is a possible sign of an attack. Network traffic reports provide valuable insights into preventing such attacks.[1]

Traffic volume is a measure of the total work done by a resource orfacility, normally over 24 hours, and is measured in units oferlang-hours. It is defined as the product of the averagetraffic intensity and the time period of the study.
A traffic volume of one erlang-hour can be caused by twocircuits being occupied continuously for half an hour or by a circuit being half occupied (0.5 erlang) for a period of two hours. Telecommunication operators are vitally interested in traffic volume, as it directly dictates their revenue.
