On Efficient Candidate Path Selection for Dynamic Routing in Elastic Optical Networks

Abstract

Elastic Optical Networks are based on the Orthogonal frequency-division multiplexing (OFDM), thus providing a more efficient and flexible data-transferring network than fixed-grid WDM networks. In this paper we solve the Routing, Modulation and Spectrum Assignment (RMSA) problem. For this purpose, we design a new, highly efficient Adaptive Dynamic Routing Algorithm (ADRA). Our results show that it outperforms other methods from the literature.
