Quality of protection on WDM networks: A quantitative paradigm based on recovery probability

In the current field study of the survival of WDM networks using quality of protection (QoP), exist the need to adjust flexibly the QoP levels to the variety of existing demands of connection, mainly due to a lack of fairness distribution and optimal resources administration. This paper proposes a paradigm for quantifying degrees of protection service based on recovery probability for simple link failure. For the optimum design of primary and backup paths is proposed an approach based on Genetic Algorithm that calculates paths subject to QoP of each unicast request. The Experimental results indicate that the proposed approach is a promising solution to obtain less expensive and more fairness services compared to traditional protection approaches based on non-flexible QoP.
