Le reti di telecomunicazioni sono in continua evoluzione spinte da una società sempre più connessa che richiede sempre migliori prestazioni e nuovi servizi. Lo standard di telecomunicazione di quinta generazione (5G) utilizzerà architetture e tecnologie innovative in grado di soddisfare i crescenti requisiti del traffico e della qualità del servizio (QoS) per i prossimi anni. Tra i nuovi modelli introdotti da 5G, spicca il concetto di Network Slicing, che promette di rivoluzionare le gestioni dell'infrastruttura di rete futura consentendo un controllo migliore e fornendo un ecosistema per l'innovazione tecnica e nuovi casi aziendali. Nuove tecnologie, come Software Defined Networks (SDN) e Network Function Virtualization (NFV), sono proposte come il ADN di questo nuovo paradigma. I nuovi modelli integreranno SDN e NFV come tecnologie abilitanti e un'entità del piano di controllo responsabile della gestione e orchestrazione (MANO) del sistema. Questa entità, che agisce come direttore del piano di controllo di 5G, è chiamata Service Orchestrator. Le reti 5G sono atteso per essere utilizzate entro il prossimo decennio, portando prestazioni e servizi mai raggiunti prima. Tuttavia, prima di raggiungere questo punto, le nuove funzionalità e le funzioni di orchestrazione dei servizi devono essere convalidate su scenari adeguati. Su queste soggetto, questa tesi presenta un Sevice Orchestrator chiamato SENATUS, rivolto agli scenario di ricerca e test. L'architettura SENATUS proposta porta una serie di innovazioni a supporto della validazione dei futuri moduli di pianificazione della rete che saranno integrati nelle entità di gestione dell'architettura 5G. Inoltre, SENATUS viene introdotto insieme a uno scenario di sperimentazione che supporta le tecnologie SDN e NFV precedentemente menzionate. Si ritiene che il sistema aumenti lo sviluppo della prossima generazione di reti fornendo gli strumenti necessari per sviluppare il futuro piano di controllo e servizi 5G. Questa tesi è stata elaborata nell'ambito del progetto europeo Horizon 2020 METRO-HAUL.

Abstract
Telecommunication networks are continuously evolving pushed by an increasingly connected society that demands better performance and new services. The fifth generation telecommunication standard (5G) will make use of innovative architectures and technologies capable of meeting the growing requirements of traffic and Quality of Service (QoS) for the next years. Between the new models introduced by 5G, stands out the concept of Network Slicing, that promises to revolutionize the managements of the future network infrastructure by allowing a better fined-grain control while providing an ecosystem for technical innovation and new business cases. Novel technologies, such as Software Defined Networks (SDN) and Network Function Virtualization (NFV) are proposed as the DNA of this new paradigm. New models will integrate SDN and NFV as the enabling technologies and a control plane entity responsible of the Management and Orchestration (MANO) of the whole system. This entity, acting as director of the 5G control plane, is called Service Orchestrator. 5G networks are planned to be in use by next decade, bringing performance and services never achieved before. However, before reaching this point, new functionalities and service orchestration functions must be validated on suitable scenarios. On these lines, this thesis presents a service orchestrator called SENATUS targeting research and testing environments. SENATUS brings a set of innovations to support the validation of the future network planner modules that will be integrated on the management entities of the 5G architecture.
