Digital twin (DT) has revolutionized optical communication networks by enabling their full life-
cycle management, including planning, prediction, optimization, upgrade, and …

In the direction of disaggregated and cognitive optical networks, this work proposes and
experimentally tests a vendor-agnostic optical line controller architecture capable of …

Optical communications and networking are fast becoming the solution to support ever-
increasing data traffic across all segments of the network, expanding from core/metro …

This tutorial considers the evolution of software-defined networking (SDN) control for optical
transport networks (OTNs) in disaggregated scenarios, focusing on its requirements and …

Network operators are facing a critical issue on their optical transport networks to deploy
5G+ and Internet of Things services. They need to address the capacity increase by a factor …

Reliable and conservative computation of the quality of transmission (QoT) of transparent
lightpaths (LPs) is a crucial need for software-defined control and management of the …

We present and demonstrate service provisioning in partially disaggregated multi-vendor
network automation scenarios with online physical impairment validation. This work uses …

We present an implementation of streaming telemetry of optical metrics within open
hardware reconfigurable add/drop multiplexers (ROADMs). Our key achievements are sub …

Quality of Transmission (QoT) metrics are used to predict and evaluate optical transmission
performance, and have received much attention due to recent interest in real-time software …

We discuss the history, past challenges and future plans of GNPy, an open source project for
simulating physical impairments in contemporary DWDM network. The paper describes the …
