OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO
The lectures are aimed at providing theoretical and practical knowledge about modern architectures for telecommunications networks and about their control. The aim is to show different technological solutions and algorithms to control and design interworking elements within a network.
The lectures provide the necessary know-how to design and manage advanced interworking technology and investigate technological challenges, still object of research both industrial and academic, as well as quality of service provision over heterogeneous networks, satellite, space, and interplanetary networks.
The main covered topics are: Definition of QoS. Definition of heterogeneity. QoS-oriented technologies. Network control issues. QoS over Heterogeneous Networks. QoS Architectures, QoS Gateway, Relay Node and Relay Layer. Software Defined Networking (SDN), Delay Tolerant Networking (DTN).
Modalità didattiche
Lectures integrated by laboratory trials.
