Abstract

A real network with 1113 physical nodes and 1+1 protection is evaluated by varying the fraction of core/metro nodes to find the optimum network size regarding cost and power efficiency of elastic in comparison to mixed-line-rate (MLR) IP over dense wavelength-division multiplex networks. No significant benefit for any of the network concepts can be deduced, neither for a hierarchical/flat nor for a MLR/elastic network concept. On the other hand, the results confirmed that the use of the flex grid is beneficial for both MLR and elastic network scenarios.
