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

Abstract: 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 … Show more

“…The RSA problem is a particular case of the Routing and Wavelength Assignment (RWA) [5], [6], [7], [8] scheme, that is used in the Wavelength Division Multiplexing (WDM) [9], [10], [11] technologies. The EON architecture imposes to the RSA problem three constraints: (1) the wavelength continuity constraint, that is the allocation of a connection, in the same wavelength on each link along the route, (2) the spectrum contiguity constraint, that is the allocation of a connection on contiguous FS on each link along the route, and (3) the spectral conflict constraint, that is a connection allocated to a certain spectral resource, cannot overlap with the spectral resources of other connections.…”
