Um componente de network slicing para o suporte de multi-inquilinos nas RANs do LTE.
Resumo
As redes 5G pretendem integrar “network slicing” em sua arquitetura visando satisfazer os diferentes níveis de serviços de uma quantidade massiva de dispositivos. Network Slicing apoia-se em tecnologias de softwarização, como SDN e NFV, para instanciar slices (redes virtuais) sobre um mesmo substrato físico. Esses slices são mutualmente independentes e customizados de acordo com as necessidades dos usuários. Este trabalho introduz o Otimizador de Slices, um componente desenvolvido como uma extensão do evolved NodeB das redes LTE, responsável por concretizar o conceito de network slicing na transmissão de tráfego downlink das redes LTE. Este componente recebe informações sobre slices oriundas de múltiplos Provedores de Serviços e, a partir da análise dessas informações e do estado da rede, o componente proposto seleciona o melhor slice a ser escalonado no momento. Simulações foram realizadas para avaliar nossa proposta e mostrar os benefícios dela, como a melhora da QoS ofertada aos usuários finais.
