Dynamic adaptive spectrum allocation in flexible grid optical network with multi‐path routing

IET Communications, Volume 15, Issue 2, Page 211-223, 17 January 2021., 2021
Abstract Fragmentation is one of the major issues in elastic optical network (EON) due to its dynamic characteristics which may possibly degrade the spectrum efficiency. Several techniques have been presented in the literature to get the optimal solution of this problem while multi‐path provisioning comes out to be very compelling among them.
