Network availability is becoming a key aspect for next generation networks. Operators and service-providers are struggling to keep the network total cost of ownership (TCO) under control while providing seamless connectivity to end-users. In the same context, the authors investigate the benefit of a framework exploiting real-time optical performance to compute restoration paths while executing dynamic layer-0 (L0) restoration. This investigative study evaluates total network cost and is based on five reference networks with a five-year traffic growth model between two network-operation modes-i) a traditional framework where dynamic L0 restoration path and resources are calculated with offline planned "end-of-life" (EoL) optical performance data and ii) a real-time framework where dynamic L0 restoration path and resources are calculated with real-time calculated "current-state-of-life" (CoL) performance data.
