Abstract :
Dynamic flexi-grid optical networks are investigated with respect to the path establishment cost and spectrum and modulation format assignment policies. The role of spectral fragmentation with respect to the spectrum granularity and the benefit to distance adaptive OFDM flexi grid networks compared with rigid grid counterparts is established.
