Uso de un simulador de red óptico híbrido para el estudio de redes 5G

The development of mobile telecommunication is a constant process and a challenge to enhancing mobile network quality of service. There is a high demand to add new features and improve higher data rates, greater reliability, energy efficiency and security as well as cost reduction. Beginning with First Generation (1G) networks to the promising Fifth Generation (5G) which could be implemented by 2020. The evolution in the traffic on the Internet has greatly increased in recent years. A large number of applications and devices have appeared demanding different requirements to the current system. Prevalent 4G generation (LTE) systems development will continue with new 5G generation radio technology, which will provide us to access to any kind of information anywhere and anytime with very low latency and jitter. Due to the capacity limitations found in present communication networks, a new architecture which could bring us benefits to get much more information appears as an alternative: Centralized Radio Access Network Architecture (C-RAN). And with it, the fronthaul network and the Common Public Radio Interface (CPRI) solution. This thesis will present the application of some 5G fronthaul concepts to a Hybrid Integrated Optical Network (IHON) event-driven simulator programmed in C. Concepts as Common Public Radio Interface over Ethernet (CPRIoE), backhaul and fronthaul traffic or 3-Level Quality of Service (QoS) scheduling for optical aggregation in data centers are studied. The key feature concepts shall be examined and their impacts on the efficiency network shall be analyzed. One of the biggest challenges for this is to get the highest traffic success rate in the network when it is working with fronthaul and backhaul functionalities in the same infrastructure.Escuela Técnica Superior de Ingeniería de TelecomunicaciónUniversidad Politécnica de Cartagen
