Optimal Selection of sigma-Cycle for Optical Networks. An approach based on Genetic Algorithm

Abstract

The study of prevention and protection against failures is a central problem in Optical Networks due to the growth of capacity demand for data transmission, especially with the Internet traffic. Without protection, failures of links or nodes cause huge losses of data. The ?-Cycle protection is a novel approach based on pre-configured protection cycles to provide a fast recovery for single link failure. This work proposes a Genetic Algorithm to solve the ?-Cycle protection question. Experimental tests carried out on different topologies have shown that this new proposal is a promising approach to achieve better results when compared to a well-known state-of-the-art alternative called Capacitated Iterative Design Algorithm - CIDA.
