Abstract
Elastic Optical Network (EON) architecture has been proposed as a promising technology for a new generation of OFDM networks. It is based on the concept that spectrum can be split into smaller slices than are used currently in the fixed-grid network. It allows better spectral utilization and support for bit rates over 100 Gb/s. EONs arise with the problem of routing and spectrum allocation (RSA). In this paper, we propose a Genetic Algorithm (GA) to solve the RSA problem with multicast flows. Different selection and crossover strategies are presented. Extensive numerical experiments are performed to select the most appropriate combination of operators and tuning parameters of the GA algorithm in the context of the RSA problem. Obtained results show that GA can be applicable.
