However, the Internet does not provide suitable Quality of Service (QoS) to guarantee the users, where several limitations compromise the users' Quality of Experience. Therefore, Internet Service Providers (ISPs) are including new technologies and management techniques to evolve to Future ISPs (FISPs). One promising technique for FISPs is the slicing of their network resources among clients and delivered services, where a strategy to define the structure of each slice is essential to improve QoS and resource utilization. Additionally, FISPs should consider the elastic resource utilization of the clients within periods of time through the day. Within this context, this article presents several strategies to define slices based on the daytime bandwidth requirements of the clients, where each strategy designed has singular characteristic that enhances aspects of the FISP, such as number of clients, resource saturation, bandwidth availability, adaptation, and others. Numerical results, considering existing network infrastructures, suggest that each strategy improves one or more of the FISP aspects according to its designing COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPES CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQ FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP Fechado
