Conventional optical networks are limited by static operational methods that hinder their
scalability and effectiveness. As networks operate with reduced margins to maximize …

In optical transport networks, failure localization is usually triggered as a response to alarms
and significant anomalous behaviors. However, the recent evolution of network control and …

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 …

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

We demonstrate end-to-end service provisioning in a fully disaggregated optical network
using open software interfaces. The GNPy quality-of-transmission estimator is extended with …

Failure management in optical networks usually deals with the processing of alarms,
including alarm classification. The alarms data obtained from network management systems …

In the operation of information technology (IT) services, operators monitor the equipment-
issued alarms, to locate the cause of a failure and take action. Alarms generate …

With the commercialization of digital coherent transmission systems, optical transport
technologies have been disaggregated for commercially available. This evolution has …

The Open ROADM ecosystem enables greater flexibility in deploying optical networks
through centralized SDN management and intelligent service orchestration. However, since …

Given the continuous growth of data traffic demand, the optical network management of
current infrastructures have become a key factor: Internet pervasiveness has enlarging fast …
