— The increasing amount of traffic in the Internet has been accommodated by the exponential growth of bandwidth provided by the optical networks technologies. However, such a growth has been also accompanied by an increase in the energy consumption and the concomitant green house gases (GHG) emissions. Despite the efforts for improving energy efficiency in(More)
In this paper, routing optimizations based on energy sources are proposed in dynamic GMPLS controlled optical networks. The influences of rerouting and load balancing factors on the algorithm are evaluated, with a focus on different rerouting thresholds. Results from dynamic network simulations show that rerouting strategies can lower CO 2 emissions(More)
Real-time analytics of anomalous phenomena on streaming data typically relies on processing a large variety of continuous outlier detection requests, each configured with different parameter settings. The processing of such complex outlier analytics workloads is resource consuming due to the algorithmic complexity of the outlier mining process. In this work(More)
Despite the significant degree of technological maturity reached by large-scale optical transmission infrastructures, new critical issues are emerging as side effects associated to their energy consumption, environmental impact and related costs, now accounting for an important part of the networks' operational expenditures. To face this problem, we propose(More)
