# Traffic Engineering Framework

This framework can help network operators decide distances between routers within an autonomous system for intradomain routing . This uses the following steps:

1. Measure: Observe how the network flow is happening at the moment. This involves looking at the current set of shortest paths and the capacity of each of the links.
2. Model: Predict how a change in weights would affect these paths and capacities on the links.
3. Control: Update the link weights and go back to the first step to check your model was correct.
