Energy efficiency in backbone optical networks can reduce the carbon footprint while preserving performance levels. When embedded in computational logic, core functional traits like lightpath routing, will be performed aiming at better resource utilization from an energy perspective. Simulating the procedure of energy-aware lightpath routing and establishment by means of software tools can lead to decisions about the characteristics a heuristic method should include to fulfil its purpose, i.e., reduce energy consumption. Also, elaborate comparison and evaluation between heuristic methods can be achieved through simulation. The main internal parts of software simulator design and implementation will be presented in this chapter, along with network environment parameters that affect their performance. Finally, an energy-efficient heuristic method is designed, implemented and simulated with the purpose of reducing energy consumption by adhering to all presented simulation principles.
