We demonstrate a packet-optical differentiated survivability mechanism implemented in P4 switches using gNMI telemetry. The controller detects the premium slice interruption and switches it to an alternative path reducing the throughput of the regula

We discuss the potential of deploying a network digital twin to support future data-driven optical networks implementing advanced telemetry. Use cases of intent-based connection allocation and soft-failure localization are addressed.

We demonstrate packet-optical intent-based networking with survivability in tents in a Mininet-Optical testbed. The intent agent negotiates intents with users based on path availability and allocates end-to-end connectivity services.

Wireless and optical communication systems not infrequently are disrupted by intersymbol interference (ISI). Wireless communications are degraded by multipath propagation in the wireless channel, while optical communications are degraded due to chrom

We demonstrate a soft-failure localization framework using SDN-based network-wide telemetry. Soft failures are generated in a small-scale laboratory environment and collected in an SDN architecture. Failure localization is accomplished by ML algorith

Targeting soft failure localization, we present a machine learning approach using SDN streaming telemetry of network-wide parameters. The artificial neural network only requires a few training scenarios to achieve adequate interpolation performance.

Critical telecommunications infrastructures, such as the modern Datacenters and 5G networks, require a reconfigurable optical add/drop multiplexer (ROADM) optical network (ON) backbone with high availability. In such ONs, the reduction of the time to

Optical communication systems operating with high data-rates and dual-polarization are invariably disrupted by chromatic and polarization mode dispersions. Fixed filters usually mitigate chromatic dispersion, but polarization mode dispersion (PMD), d
