In this work a mixed integer optimization linear programming (MILP) model applied to IP over WDM networks, in order to reduce network energy consumption. Simulations were made based on a real network topology as well as on forecasts of traffic matrix based on statistical data from 2005 up to 2017. Several techniques were tested an the bypass technique yielded up to 88% savings, as well as absence of transponders between IP and WDM layer potentially saving up to 48%, by shortest path routing technique. Energy aware routing optimization model, has led to an overall reduction in consumption up to 51% in 2017.
