Avaluació de la generació de serveis de xarxa en escenaris híbrids basats en SDN, NFV i SFC

Abstract

Currently, we are experiencing the era of digitization that is suffering challenges due to the fast growth in demand of bandwidth and services innovations which are leading to traditional networks at its limit. This situation is created from a change in telecommunication market that is in constantly development. Although networks have improved over time, the new needs exceed their reach and have to face up to new demands. This set of challenges leads to the creation of new solutions in order to be able to adapt current needs easily keeping up the levels of demand and service. The networks and services industry is changing into virtualization approach and moving away from the proprietary hardware in order to provide scalable, elastic and agile networks that make easier the development of services on demand in the shortest time and with the lowest cost possible. Transforming technologies SDN, NFV and SFC provide new possibilities completely changing the way of designing, deploying and managing networks offering notable improvements and increasing their efficiency. For this reason, there is a huge spectrum of chances in the investigation of these techniques in order to achieve a success in its implementation. The aim of this work has been focused on search information about these emerging technologies and their practical implementation through different scenarios using various methodologies (automatic installation, manual installation and the use of a predefined OPNFV scenario). The deployment of this scenario and its operation, can be extrapolate it to real environments and build a reliable teaching or production platforms where. The maturity lack of these techniques has complicated the procedure and the initial aim could not be fully achieved. Nevertheless, it has been concluded that the nested virtualization causes instability in configurations and it has been confirmed the global operation of SFC in the integration of the different projects has been fulfilled.
