Optical path computation element and its interwork with the network management system are investigated for planning and operation of all-optical networks. We successfully verified fast optical-path computation considering physical impairments and wavelength continuity.
In transparent WDM networks, the optical signal crosses various equipments (cross-connect, amplifiers and sub-fibre) and while the signal is propagated, the optical components causes their degradation. Thus, paths with low quality signal should be avoided, especially when the application requires quality of service (QoS). In this context, an appropriate allocation of resources requires encompassing...
The quality of transmission (QoT) estimators, envisaged to optimize the impairment constraint routing and wavelength assignment (IC-RWA) in optical transparent networks, are often assessed in a steady configuration by means of re-circulation loops and/or transmissions simulations. In such context the powers of the WDM channels are regularly fixed to a given set of values related to a given point of...
