Abstract
Pre-programming Layer-0 optical protection path restoration speeds is provided based on available path margin. Higher layer routers and switches can be made aware of the expected Layer-0 restoration time, and their switch time can be programmed accordingly. The proposed method can provide users an option to program a restoration speed for a specific photonic service on a per restoration path basis. The method can highlight which services will potentially be impacted by the selected restoration speed on that path. The user can proceed with the selected speed for restoring high priority layer-0 services even if that means the fast restoring event can potentially impact other low priority services already in-service on the restoration path.
