| Περίληψη: | 5G comes with a new rich set of features and capabilities and requires an environment where services will be created and destroyed instantly, with a click of a button, in a fully automated manner. In order to achieve this, technologies like SDN and NFV play a vital role in the architecture of the new 5G networks. Moreover, network slices are a prerequisite in order for the operators to be able to offer 5G services over shared infrastructure, using network slices with different resource requirements. The purpose of this thesis is threefold: Firstly, to describe the basic concepts of the aforementioned technologies and survey current state of the art specifications related to them. Then to deploy and configure the core testbed that will evolve to be part of Patra’s open 5G platform. Finally, to develop the source code and configuration files for the creation and configuration of a Network Slice on top of the NAM testbed with the use of Open Source MANO orchestrator, that emulates the functions of an end-to-end open 5G service.
