Execution time improvement for optical amplifier cognitive methodology in dynamic WDM networks

Optical networks are facing complexity and management challenges because a multi-technology infrastructure is required to support an ever-increasing traffic volume and dynamicity. In this heterogeneous context, we recently proposed a Cognitive Methodology to adjust the gain operating point of optical amplifiers using case-based reasoning. In this paper, we evaluate the execution time and introduce a modification on the original Cognitive Methodology to improve this critical parameter without degradation on the optical performance. The obtained results show an execution time reduction of around 92%, with the same (or even better) optical performance.
