    Abstract

    We study the performance of the local-to-egress restoration method in GMPLS controlled optical networks, when a limited number of wavelength converters are available. We evaluate the recovery percentage for a converter-saving label assignment scheme and compare its performance to a simple scheme with and without releasing resources that are not used after the failure (stub release). Our simulations show that the converter-saving label assignment scheme without stub release outperforms the simple label assignment scheme with stub release, to the extent that stub release can be avoided without sacrificing restorability.
