We experimentally present a lab trial of PCE-based OSNR-aware dynamic restoration in multi-domain GMPLS-enabled translucent WSON, assessing the overall feasibility and quantitatively evaluating the service disruption time and path computation latency during end-to-end lightpath restoration.
Key technologies for manageable and controllable translucent optical networks are reviewed. The overall demonstrations on PCE-based and fully distributed translucent optical network are also presented.
Multi-domain resilient translucent WSONs with distributed GMPLS control and centralized PCE/GMPLS control were experimentally demonstrated and quantitatively compared in terms of lightpath provisioning latency and service disruption time in case of an inter-domain link failure.
A resilient translucent optical network controlled by a PCE and extended GMPLS controllers was successfully demonstrated, while quantitatively evaluating the path computation latency and service disruption time during end-to-end lightpath restoration.
