Abstract
Core optical networks using reconfigurable optical switches and tunable lasers
appear to be on the road towards widespread deployment and could evolve to all-optical mesh
networks in the coming future. Considering the impact of physical layer impairments in the
planning and operation of all-optical (and translucent) networks is the main focus of the
Dynamic Impairment Constraint Optical Networking (DICONET) project. The impairment aware
network planning and operation tool (NPOT) is the main outcome of DICONET project, which is
explained in detail in this paper. The key building blocks of the NPOT, consisting of network
description repositories, the physical layer performance evaluator, the impairment aware
routing and wavelength assignment engines, the component placement modules, failure handling,
and the integration of NPOT in the control plane are the main contributions of this study.
Besides, the experimental result of DICONET proposal for centralized and distributed control
plane integration schemes and the performance of the failure handling in terms of restoration
time is presented in this study.
