Reliability-Aware Network Slicing in Elastic Demand Scenarios

The Internet is an essential tool for society as a whole, being the basis for several services. This importance has increased the requirements for Internet service providers (ISPs). The current Internet infrastructure is limited, which often compromises the quality of service and quality of experience of users. Therefore, ISPs need to evolve their technologies and management capacity. One key approach is network slicing, which allows the management of reliability and elastic resource demand. This article discusses the reliability requirements of the network slicing process as well as the features and challenges of elastic demand scenarios. Additionally, it presents a reliability strategy for network slicing. The results from the experiments performed, using a dataset with real network demands, suggest that the reliability strategy mitigates the impact of physical failures over the Internet access service.
