To deal with exponential traffic growth, Elastic Optical Networks (EONs) are necessary because they enable to provide large capacity transmissions. In EONs, multiple widths of spectra are assigned to optical paths. Therefore, fragmentation in frequency domain degrades network performance. We propose a spectrum allocation method to reduce blocking probability and node costs, especially in spatially...
We propose novel optical node architecture based on the Architecture on Demand concept with sophisticated spectrum and core allocation in Multi-Core Fiber Elastic Optical Networks. More than 85% of flexible spectrum selective switches can be reduced by replacing fixed-grid MUXs/DEMUXs.
