Traffic engineering

In German, traffic engineering describes the process that involves the collection ( analysis ), design and optimization of data flows and paths in computer networks . At the beginning of the process there is a survey of the requirements, be it from an existing situation or on the basis of comparison data (e.g. from comparable requirements). Thereafter, by means of forecast calculations of the actual demand for communication paths or capacities (who is connected to whom - the so-called traffic matrix or Traffic Matrix ), suitable techniques (IP- VPN , MPLS , Frame Relay , ATM , adaptation of IGP -Linkgewichten) Bandwidths , capacities of the network elements ( routers , switches , nodes) and QoS parameters determined. The resulting changes should then lead to an optimization of the data paths: low load, minimal losses and runtimes, optimal routing are the goal.

In English usage called Traffic Engineering , the traffic planning and Teletraffic engineering the above facts.
