Abstract

The design of a survivable optical network has been extensively studied, but most of the work has confined to wavelength level path or link protection and restoration, while the other work has relied on fiber protection/restoration. Each scheme has its own pros and cons. Based on these existing schemes, we have presented a hybrid protection scheme (HPS), which divides the optical layer into wavelength layer and fiber layer, to provide more effective survivability for multiple fiber mesh-based WDM networks. In this paper, we will further extend HPS concepts to allow local wavelength level recovery in order to resolve breakdown in few wavelengths by sharing the resources from fiber level recovery. A detailed survivable node architecture design is proposed, and how this node architecture provides network survivability against various failure scenarios is presented. The performance of multifiber network and single fiber network is also compared; finally, the various protection schemes are evaluated.
