traffic engineering - Computer Definition
The inexact science of predicting the volume of future traffic and equipping a network with enough switching and transmission resources to handle that volume, thereby providing end users with a satisfactory grade of service (GoS). See also Erlang, Erlang B, Erlang C, Equivalent Queue Extended Erlang B, Extended Erlang B, GoS, Poisson distribution, and traffic.
The ability to guarantee performance in a network for a certain amount of capacity for a certain amount of time. Also known as "traffic management," it implies the ability to analyze the current traffic load and dynamically make necessary adjustments to accommodate the different types of traffic or changing conditions. ATM is known for its traffic engineering capabilities. See traffic engineering methods, traffic shaping, traffic policing and ATM.
