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...
A centralized path computation element integrated with optical performance monitoring was developed for transparent optical network. Appropriate path establishment satisfying requisite transmission performance was successfully confirmed in the testbed.
