On the performance of dynamic source aggregation of sub-wavelength connections in EONs

In elastic optical networks, heterogeneous traffic demands are typically supported by a single type of bandwidth-variable transmitters, which is not always spectrum and cost efficient. In light of this, we recently proposed a novel algorithm for dynamic aggregation of same source but different destination sub-wavelength connections in elastic optical networks, aiming to obtain both transmitter and spectrum usage savings. In this paper, the performance and feasibility analysis of the proposal is presented. The obtained results demonstrate considerable improvement in the network spectrum utilization, as well as a significant reduction in the relative network cost.
