This paper proposes new energy efficient routing algorithms in optical core networks, with the application of solar energy sources and bundled links. A comprehensive solar energy model is described in the proposed network scenarios. Network performance in energy savings, connection blocking probability, resource utilization and bundled link usage are evaluated with dynamic network simulations. Results...
In this paper, routing optimizations based on energy sources are proposed in dynamic GMPLS controlled optical networks. The influences of re-routing and load balancing factors on the algorithm are evaluated, with a focus on different re-routing thresholds. Results from dynamic network simulations show that re-routing strategies can lower CO2 emissions compared to the basic energy source routing scheme,...
Awareness of energy consumption in communication networks such as the Internet is currently gaining momentum as it is commonly acknowledged that increased network capacity (currently driven by video applications) requires significant more electrical power. This paper stresses the importance of approaching the problem is a coordinated manner looking at all part of the end-to-end system as a whole.
