Protection schemes for WDM mesh networks are typically based on the single-failure scenario. However, the single-failure model is not realistic since the failure of network components is probabilistic. On the other hand, different applications or end users need different levels of fault tolerance. In this work, we assume a probabilistic failure environment and choose the connection reliability as...
We present a new approach to the virtual-topology reconfiguration problem for wavelength-routed, optical wide-area networks under dynamic traffic demand. By utilizing the measured Internet backbone traffic characteristics, an adaptation mechanism is proposed to follow the changes in traffic without assuming that the future traffic pattern is known. In that sense, our work differs from previous studies...
