Resumo


A virtualização de funções de rede e a desagregação de componentes demandam o gerenciamento dos recursos da Radio Access Network (RAN) através de um controlador central conhecido como RAN Intelligent Controller (RIC). Os RICs da Open Networking Foundation (ONF), O-RAN Software Community (OSC) e OpenAirInterface (OAI) fornecem soluções quase completas para o gerenciamento da RAN. Neste artigo, setups são criados para cada RIC que testam operações essenciais relacionadas ao monitoramento de Key Performance Indicators (KPIs), ao slicing de recursos da rede ou a ambos. Usando esses setups, monitoramos as métricas da RAN por meio de interfaces gráficas e demonstramos a criação de slices de rede.
