| Abstract | Traditionally, the main focus for optical transmissions in wavelength division multiplexing (WDM) networks has been on how to increase the transmission rates. However, there is currently strong interest in green communications, which includes operating communication networks with high energy efficiency. This research investigates the problem of energy efficient routing and wavelength assignment (RWA) in a WDM network taking into consideration the optical reach, which is the maximum physical transmission distance of a lightpath. The energy efficient RWA problem under consideration is formulated as an integer linear programming (ILP) problem whose objective is to minimize the energy consumption for supporting a given set of traffic demands. The ILP problem is solved using the Python programming language with the PuLP package for random traffic scenarios in ring, grid, and mesh topologies. Simulation results from different network and traffic scenarios are compared, with special attention to how the optical reach affects the overall energy consumption. The results indicate that a longer optical reach does not necessarily lead to a lower energy consumption by the network when the associated energy consumption of a switch port increases with the optical reach. |
