Abstract

This paper provides a survey on existing survivability related problems and include the new algorithm based on existing algorithms. Survivability has become an important issue and topical subject in WDM networks. This paper reviewed the literature on survivability against multi-domain or link failures to ensure reliability in WDM networks. Survivability in multi-domain optical networks is very important, only few studies have been proposed in literature. The paper is related to protection technique in inter-domain link of multi-domain network combining the p-cycle and wavelength assignment.
