5. Required knowledge Algorithm theory, Databases, Infocommunication networks

7. Objectives, learning outcomes and obtained knowledge The primary objective of “Network Planning and Operations” is to provide students with an insight into the methodology of planning and operations of infocommunication networks. The subject specialises in the related practical knowledge through the practice of elementary planning and operation/configuration methods and the analysis of ready-made solutions.
In the framework of the subject, the theoretical foundations of the structures and operations of IP-based networks are reviewed, starting from packet-switched communication through route selection to network services. Task-oriented network modeling based on standard approaches is discussed in detail, as well as the selection and application of practical design and analysis methods. The topic of network registration, configuration and operations is processed by discussing modern DevOps-based methods that support automatic orchestration.
