What is the usage of traffic engineering in telecommunication?
Traffic Engineering is a very important part of telecommunications networks. You cannot decide which topology will be the best, or even workable if you don’t have traffic measure, or a probabilistic model about how users traffics will behave. The second important aspect if about quantification. You need to quantified the amount of traffic per trunk line. For data networks the process is easy than telephone channel networks. In data networks you could ‘add’ all traffics in a route and define a ‘big channel’ with the ‘whole data speed’, but; If you want to separate traffics with different quality of service, it could be better to define different channels. In fact you need to use traffic engineering every time you need to define a trunk line and dimension the amount of data that will run over it. No network could be done properly without traffic engineering.
