| Sumario: | Upon the demanding requirements brought by next-generation services, current network infrastructures are required to evolve in the way they manage different types of resources at the data layer. To this end, a set of novel technologies have risen to provide the functionalities needed for this evolution, thus representing also a change in the architectural paradigm for future network implementations.Regarding this, the following PhD Thesis presents an analysis on these specific technologies, focusing on the particular case scenario of inter/intra-DCNs. In this way, the introduction of SDN, NFV, Network Slicing and optical technologies in these scenarios is investigated, with the goal of identifying current technical issues that can be solved by the design and application of new software-based techniques, as well as with the development and/or augmentation of architectural components. With this purpose, this thesis defines a set of proposals, considering crucial aspects such as the required SDN-control of optical devices to allow the control of hybrid electric/optical networks, the necessity for a dynamic optical topology discovery mechanism capable of exposing accurate network information, and the analysis of the existing gaps towards the definition of a common architecture for supporting upcoming 5G and beyond communications.In order to validate these proposals, a set of experimental validations through the use of specifically defined testbeds is also presented, to prove the enhanced control, orchestration, virtualization and management of resources in the seek for optimizing their utilization. The results exposed in this thesis, besides demonstrating the correct operation of the introduced methods and components, open the path towards new ways of adapting current network deployments to the challenges driven by the start of a new era in telecomunications. |
