A Quinta Geração de Redes Móveis (5G) apresenta-se como a mais revolucionária geração de redes móveis até agora. Impulsionada por novos desafios que tecnologias emergentes e casos de uso promovem, o 5G será essencial para potenciar novos serviços e lidar com a exigência dos requisitos que daí advêm. Para atingir estas metas definidas para o 5G, novas tecnologias destacam-se como as Redes Definidas por Software (SDN), a Virtualização de Funções de Rede (NFV) e as Slices de rede. Estas últimas serão essenciais para garantir Qualidades de Serviço e Experiência a serviços verticais que necessitam de garantias de segurança e isolamento dos seus dados enquanto beneficiam de redes virtuais dedicadas cujos elementos físicos são partilhados para outras Slices ou Funções de Rede. Desta forma, os Operadores de Rede conseguem fornecer novos e melhorados serviços enquanto garantem menores custos operacionais e capitais. No entanto, tecnologias como o Slicing de Redes encontram-se permaturas e um sistema prático para a sua gestão entre o cliente e o fornecedor será essencial para alcançar eficientemente os objetivos da mesma. Esta dissertação apresenta uma prova de conceito de um gestor de Slices de Rede 5G através de uma plataforma web desenvolvida para o efeito.
The Fifth Generation of Mobile Networks (5G) is presented as the most evolutionary generation of mobile networks to date. As new and upcoming technologies and use cases promote new challenges, 5G will have to meet these demands. In order to do this, new technologies are being introduced, such as Software Defined Networks (SDN), Network Function Virtualization (NFV) and Network Slicing. Network Slices will be essential to guarantee customized Quality of Service and Experience to vertical industries and use cases while they benefit from dedicated virtual networks whose physical elements are shared by other Slices or Network Functions. Consequently, Network Operators will provide new and improved services while guaranteeing lesser operational and capital costs. However, technologies such as Network Slicing are still in a premature state and a practical management system is essential to effectively reach its goals. This thesis presents a proof of concept of a 5G Network Slice Manager through a web platform specifically developed for this purpose.
