Traffic Engineering Primer and Calculator
Posted: 04/19/2002
Abstract:
The popularity of voice over IP has exposed many data people to some new terminology related to telephone traffic engineering. For example, grade of service, blocking and Erlang are terms that may be new to some data professionals. This tutorial is intended to explain some of these terms as well as describe a useful tool for calculating service levels in a voice environment. The accompanying calculator makes traditional telephone traffic engineering tables obsolete. It quickly provides blocking probabilities, number of circuits required, or the traffic carry capacity of a given number of circuits depending on what information the user requires. Network designers will find this to be a useful addition to their design tool kits.
