As WANs continue to form the framework for deploying mission-critical applications, the need for fault resilience and fast restoration assumes greater importance. This paper examines existing schemes for fast restoration signaling in a wavelength-routed optical core and introduces an improved signaling scheme based on Optical Burst Switching and Just-Enough-Time path establishment. Scaling experiments show that the proposed scheme outperforms existing schemes.
