Research Field: Step 4: Compare the Networks
In this step researchers compare two network layouts in terms of performance, reliability, etc. This is achieved by building a simulation model based on the new network design, and running the current traffic profiles and the future usage scenarios from Step 2: Evaluate the Network across this model. If the comparison is not favourable the modelling in the design step should be investigated.
NDSG usually use simulation for this step and make statistically valid comparisons.
