The goal of energy cost-aware Routing and Wavelength Assignment (RWA) is to minimize the total electricity expenditure in an optical network. While effective, just aiming to reduce the electricity consumed does not necessarily mitigate the environmental impact. A new approach is required to reduce the emissions produced as a by-product of RWA. We present a method for doing so through the use of Mixed...
Manycasting is an emerging communication paradigm which allows a single source to reach multiple destinations while providing flexibility in the selection of which destinations to connect with. Traditional wavelength division multiplexed (WDM) networks do not support the all-optical splitting of signals to multiple output ports as required by point-to-multipoint communication schemes. Previous work...
In this work we propose anycast routing methods to improve the performance of reconfigurable WDM networks under the variations in the IP traffic. We first investigate anycast communication via impairment-aware anycast routing (IAAR); our simulation results show significant improvement in the blocking probability. We also investigate the proposed load-aware anycast routing (LAAR) for the varying traffic...
