Abstract :
A field trial of all-optical networking by an intelligent control plane based on generalized multiprotocol label switching (GMPLS) technologies was successfully conducted with the assistance of optical performance monitors (OPMs) capable of monitoring the in-band optical signal-to-noise ratio (OSNR). In the field trial, the GMPLS control plane was applied to not only fast provisioning of all-optical paths but also to end-to-end restoration of optical paths triggered by OPMs. Reliable and stable network operation was achieved as a result of applying the GMPLS control plane and OPMs.
