Wavelength division multiplexing (WDM) divides the huge bandwidth available on a fiber into several non-overlapping wavelength channels and enables data transmission over these channels simultaneously. Failure of the optical fiber causes loss of huge amount of data which can interrupt communication. There are several approaches to ensure network survivability. In survivability, we consider dedicated...
In this paper, we address the problem of providing survivability in elastic optical networks (EONs). In EONs, unlike the traditional 50 GHz fixed grid, fine granular 12.5 GHz flexgrid is used and the frequency spectrum is used more efficiently. For providing survivability, we consider a recently proposed survivability approach known as pre-configured backup protection with sharing (PBPS) because of...
In this paper, we address the problem of providing survivability in elastic optical networks (EONs). EONs use fine granular frequency slots or flexible grids, when compared to the conventional fixed grid networks and therefore utilize the frequency spectrum efficiently. For providing survivability in EONs, we consider a recently proposed survivability method for conventional fixed grid networks, known...
