The class of Open and Virtualized Networks, OVN in the following, aims at giving the fundamental skills for the novel professional operators known as Network Architects. These are requested to manage networks from the physical layer up to the network lyer. To this purpose, network elements and subsystems are virtualized, relying on physical and operational mathematical/statistical models. Virtualizations are summarized as common APIs and data structures to enabling an optimal orchestration through a network operating system. The proposed analyzes will enable an open network management based on common APIs and data structures. The teaching method will follow an application-oriented introduction of concepts. To this purpose, students will be required to develop Phyton module performing simple operations, exploiting the open source library GNPy of the Telecom Infra Project. Thus, students can operate in a license-free development environment, using their own laptop for virtual lab experiments. All the theoretical concepts will be proposed in the framework of a backbone transparent optical network supporting the deployment of different services including 5G low-latency connections and high-capacity data-center interconnections, as well as contents delivery services. After proposing an overview of the framework, the course will propose the fundamental concepts of the optical network elements (transceivers, fiber propagation, amplifiers and switches) with the purpose to enable the use of the APIs virtualizing their operational modes. Then, the concepts of network planning, management and control will be introduced, starting from application examples. Theoretical lectures will be integrated by exercises, on the following topics • Introduction to Python. A practical introduction to the basics of Python programming and the Object-Oriented paradigm. • Introduction to the GNPy. Introduction to the Python-based open source GNPy software (https://github.com/Telecominfraproject/oopt-gnpy). The students will learn how the software provides an abstraction of the single physical elements - the building blocks - of an optical network. • The Optical Network Abstraction. Using the building blocks given by GNPy the students will operate on the virtual models of the physical layer of a complete optical network as a weighted graph. • Network operations. The students will learn how to route data traffic through an optical network. • Deployment of services in the network. The student will optimize the data traffic through your optical network to support the requirements of services such as best Quality-of-Service or low-latency 5G-based services.

Teaching method will be “hands-on”, so within lectures, students will be required to their own laptop so that theoretical concept will be immediately applied in simple exercises or reviewing examples. For approximately 1/3 of the available hours, the teaching assistants will support code development and in general exercise solving. The class will be organized as a series of concepts’ presentation and their application through python coding homework. Students will be required to operate on their own laptop and group working will be allowed.

Modalità di esame: Prova orale obbligatoria; Progetto di gruppo;
Exam: Compulsory oral exam; Group project;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam; Group project;
Student assessment will be performed reviewing the Python coding and results of homework. During the oral review of the homework, theoretical questions will be asked to students.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
