Power demand in networking equipment is expected to become a main limiting factor and hence a fundamental challenge to ensure bandwidth scaling in the next generation Internet. Environmental effects of human activities, such as CO 2 emissions and the consequent global warming have risen as one of the major issue for the ICT sector and for the society. Therefore, it is not surprising that telecom operators are devoting much of their efforts to the reduction of energy consumption and of the

In this work, we present a novel integrated routing and wavelength assignment framework that, while addressing the traditional network management objectives, introduces energy-awareness in its decision process to contain the power consumption of the underlying network infrastructure and make use of green energy sources wherever possible. This approach results in direct power, cost and CO 2 emissions savings in the short term, as demonstrated by our extensive simulation studies. with honors). He worked with the Federico II University and with the Italian National Institute for Nuclear Physics (INFN) within several national and international projects. His research interests are mainly focused on energy-aware RWA algorithms and protocols for telecommunication networks and energy-oriented optimizations for grid/cloud computing.
