Abstract

With the emergence of new applications and requirements it became necessary to create new monitoring and reactive configuration mechanisms to try to meet the SLAs (Service Level Agreements). In WDM (Wavelength Division Multiplexing) optical networks, one way of trying to fulfill these agreements is by using pre-established protection paths. However, despite guaranteeing that traffic will be rapidly routed to its protection path in case of failure, there is no guarantee that the latter will be capable of meeting the contracted SLA in accordance with the bit error rate of its links. In this article we propose a scheme for monitoring and selecting the SRLG (Shared Risk Link Group) protection path disjointed from the main path using Genetic Algorithms, Fuzzy Logic in a PBM (Policy Based Management) platform denominated GAFUDI.
