Abstract

The author addresses the problem of self-healing capability to recover from network failures for WDM optical networks. One problem in realizing such survivable WDM networks is the inefficient utilization of large spare resources (wavelengths) designed for restoration of the failed traffic, which might not happen frequently. We study "common-wavelengths" design scheme to increase the utilization efficiency of these resources. The "common- wavelength" is an approach that allows some working paths under the failure to efficiently use the available common-wavelengths in the network. The effectiveness of this proposed approach and the effect of physical and traffic connectivity are investigated via simulations. Thus, the survivable WDM networks can be cost effectively designed according to the reliability levels of all working paths in the network. © Springer Science+Business Media B.V. 2010.
