N2 - Optical restoration is known to be an effective way to save on network overall cost, using the same available equipment previously used before the failure occurs. However, when backup paths are too long, some regenerators can be required bringing into question the expected gain. In this work, we show that transponder datarate elasticity is a successful approach to address this issue, taking benefit of best effort traffic low priority in a multilayer context.
