Investigating solutions that increase the system capacity and security as a function of targeted application ranging from ultra-long haul to short reach connections. Several multiplexing techniques (polarization, wavelength, frequency, time, and space) are considered. Optical devices, sub-systems, and systems are designed, implemented and validated through laboratory characterization, measurements and field trials.


Devising novel modulation/coding formats and equalization techniques for increasing bit-rates, achievable distances, and robustness to impairments in fiber-optic communication. Both linear and nonlinear regimes are considered, as well as long- and short-reach systems. Channel models based on the nonlinear Fourier transform are investigated with the aim of overcoming the nonlinear capacity crunch. Efficient original performance evaluation methods are available.



Tackling the integration between novel highly-programmable optical transmission techniques and the relevant control plane implementing flexible optical networks. For such networks the area is responsible of designing and demonstrating experimentally SDN control solutions, traffic engineering algorithms, reliability schemes and multi-layer networking (based e.g. on segment routing), resource orchestration.



Tackling a few aspects of the recent trends of network softwar-ization. The area studies algorithm and software implementation of control plane modules for integration of IT and network resources. The main topics of investigations are: cloud and network resource management in Data Centers, security in multi-domain transport networks, network operating systems over programmable and virtualized (SDN/NFV) infrastructures, non-telecom network management (e.g. electric vehicles fleets).



In the innovation era, prominent applications in the automotive, manufacturing, health, logistics and transport sectors require to securely interconnect high-end and low-end devices by means of trusted networks and digital platforms.

This CNIT Research Area focuses on large-scale and integrated infrastructures at sub-system and system levels (from prototype embedded systems, to digital platforms, and final user applications, including an ICT fully-equipped laboratory), exploiting a large-scale testbed located at the Port of Livorno.  Our reference framework is open to partners willing to check interoperability and compliance to standards for their assets. The reference architecture is cloud-shaped: all layers (IaaS, PaaS, SaaS) feature open-source or free software modules so that open-ness towards new partners can be guaranteed.

Complex infrastructures rely on heterogeneous data sources, more specifically local sensing networks, local relational databases and external data banks.

The resulting data lake is therefore capable of:
●     ingesting structured and unstructured data;
●     storing and securing data in a scalable way;
●     allowing for catalogs and indexes without the need of data movement;
●     connecting to Business Intelligence applications via transparent APIs.

The Data Lake is managed by:
●     relational DBMS (i.e. mySQL, MS SQL Server);
●     IoT-oriented platform (i.e. Ocean Mobius complying with OneM2M);
●     document-oriented platform (i.e. MongoDB);
●     GIS platform (i.e. ESRI ArcGIS).

Jboss Teiid provides technology-independent data virtualization and exposes APIs.
For the Port of Livorno the data infrastructure exposes an Open Data layer where information about (multi-modal) transport & logistics, environmental conditions, status of operational processes can be retrieved.

As security and trust have to be considered in multi-party processes (notably in logistics) the data infrastructure makes use of InteroperaChain, a Distributed Ledger Technology (DLT) interoperability layer:
●     collecting information on the supply and distribution chain in a secure and non-repudiable way (interoperable with industrial IT platforms);
●     guaranteeing replication of information and its availability even in the event of exceptional events (e.g. disasters, cyber attacks)
●     guaranteeing end user abstraction with respect to the underlying technology, avoiding technology lock-in
●     on-boarding Port of Livorno to Tradelens (by Maersk/IBM)

For the industrial development activities the laboratory relies on a local farm consisting (to date) of:
●     Server DELL POWEREDGE R730: x1 128 GB RAM, 8 SAS disks of 300 GB disks;
●     Server DELL POWEREDGE R7425: x4 128GB RAM, with about 16 TB storage capacity (SAS and SSD);
●     VMware virtualization technology (freeware version);
●     RAID-1/RAID-6 redundancy.

An industrial tenant on CNIT infrastructure will also make use of the following services:
●     Data Lake (as discussed in page XX);
●     Owncloud (file repository);
●     GitLab (source code versioning system);
●     OpenProject (project management).

The outdoors wireless network consists of:
●     a WiFi private network covering the maritime terminal;
●     a C-ITS network supporting ETSI-compliant vehicular communications;
●     commercial mobile networks 4G/5G with specific support of NB-IoT standard protocol.

Dedicated VMs will be instantiated on the farm. A VPN tunnel will be enabled to connect industrial IT premises to the testing infrastructure.
The VMs will have access to dedicated microservices:
●     API Gateway to manage API calls;
●     RabbitMQ as message-broker for service-to-service communication;
●     Token Issuer to manage Single Sign On by JWT token;
●     Identity Server to securely access the APIs;
●     Publisher Portal Profile to publish new APIs.
●     Docker to implement microservices with container design pattern.
Industries can therefore spawn a full-fledged service in an open digital stack.

A system composed of many sensors and entities with different nature requires a real-time monitoring system capable of showing the status of the georeferenced components.

The NVIZ framework satisfies these requirements providing a development environment supporting containerized web-apps. Such applications:
●     render entities (sensors or vehicles) and their state on a 2D map;
●     interact with a OneM2M platform through a native module;
●     leverage the “subscriptions” OneM2M mechanisms to collect sensors data;
●     automatically render entities when payload satisfies a predefined data-model;
●     can display different types of data streams (such as IP cameras images).

General Aspects:

Vehicles are already connected devices. However, in the very near future they will also interact directly with each other and with the road infrastructure. This interaction is the domain of Cooperative Intelligent Transport Systems (C-ITS), which will allow road users and traffic managers to share information and use it to coordinate their actions. This cooperative element – enabled by digital connectivity between vehicles and between vehicles and transport infrastructure – is expected to significantly improve road safety, traffic efficiency and comfort of driving, by helping the driver to take the right decisions and adapt to the traffic situation.

A standardization action has been mandated to ETSI/CEN by the EC in 2008. A set of standards (release 1) is already in force. A regulatory action (“Delegated Act”) is still pending of approval by the European Parliament and the EU Council.

Integration with satellite backhaul in maritime services:

The next version of the NB-IoT smart object will be equipped with an additional transceiver providing mesh networking capability for the maritime transport scenario, to overcome the radio-coverage issues due to the cargo containers. Furthermore, the NB-IoT smart object will be integrated in a E2E system able to deliver the sensor measurements to a cloud platform via an ad-hoc satellite backhauling.

Future versions of the smart object will be designed according to 3GPP Release 17 process, where NB-IoT over Non Terrestrial Network specification activity is planned during 2021.

This asset can be exploited by industries willing to deploy monitoring applications on a 5G-like composite network infrastructure. The capability of deploying NetApps exploiting the Edge Nodes hosted in a local cloud directly interfaced with a 5G fronthaul is also offered.
