A New Approach for Multi-restrictive Routing in Translucent Optical Networks

This paper presents a new approach for multi-restrictive routing in translucent optical networks which is simultaneously aware of optical link, wavelength, and optical node constraints. Based on this novel approach, two new multi-restrictive routing algorithms were proposed, named Offline Multi-Restrictive Routing (Off-MRR) and Multi-Restrictive Routing (MRR). These two algorithms were compared in terms of execution times, network utilizations, and blocking probabilities. In all evaluated scenarios, Off-MRR achieved a superior performance in terms of execution times, while MRR achieved a superior performance in terms of network utilizations and blocking probabilities.
