The recent introduction of optical OFDM and spatial MIMO techniques has led to considerable increases in spectral efficiency and aggregate throughput for future optical networks. However, these spatial and spectral domains can also be exploited for next-generation elastic optical networking. In this paper, we introduce the first hierarchy for dynamic multidimensional spatial and spectral optical networking and complement it with adaptive coded-modulation to form the basis of a novel elastic networking concept.
