Teletraffic engineering

Traffic Engineering describes the Germans the process that has the collection (analysis ), design and optimization of data flows and paths in computer networks to content. At the beginning of the process is a collection of requirements, whether it be from an already existing actual status or on the basis of comparative data (eg from comparable requirements ). After that, by means of forecasting the actual need for connecting routes or capacities (who is connected to whom - the so-called traffic matrix or traffic matrix ), appropriate technologies (IP-VPN, MPLS, Frame Relay, ATM, adaptation of IGP link weights ) determined bandwidth capacity of the network elements ( routers, switches, nodes) and QoS parameters. The resulting changes will then lead to an optimization of the data paths: low load, minimum losses and transit times, optimal routing are the goal.

In English usage, traffic engineering refers to the traffic planning. Here Teletraffic engineering refers to the above mentioned facts.
