Abstract
The performance of the regenerator allocation
algorithms in WDM networks strongly depends on the accuracy
of the physical-layer information such as the Q factor. In
a translucent WDM network the already installed regenerators
along the lightpath are allocated based on the physical information
(Q factor) in order to maximize the quality of the optical
signal while minimizing the opaqueness of the network. The
Q factor used by the IA-RWA algorithms is usually inaccurate
due to the drift suffered by the physical-layer parameters during
the operation of the optical network. In this scenario the
allocation of regenerators is not optimized and then the performance
of the network is worsened. New regenerator allocation
schemes should be proposed in order of counteracting the
inherent and unpredictable uncertainty in the physical-layer
information.
