Routing and Spectrum Allocation with Amplifier Placement in Elastic Metro-Aggregation Networks

Abstract

We propose a quality-of-transmission (QoT) aware heuristic algorithm for the placement of amplifiers in elastic metroaggregation networks with the objective of minimizing their number while guaranteeing lightpaths’ QoT. Results show that optimized amplifier placement can lead to significant reduction of amplifiers with respect to baseline approaches.
