Introducing node architecture flexibility for elastic optical networks
TL;DR: This paper proposes a method, based on entropy maximization, to quantitatively evaluate the flexibility provided by optical node components, subsystems, and architectures and demonstrates the equivalence, in terms of switching flexibility, of finer spectrum granularity, and faster reconfiguration rate.
