Modelos para fatiamento de redes 5G

Abstract

The fifth generation of wireless mobile communications, 5G, demands diverse types of service use. One way to meet the different service requirements is to separate users into groups with similar demands in a logical and dedicated network slice. This is known as the network slicing technique. To meet the different users needs, a 5G network relies on a document containing the definitions of the service requirements in order to create new Network Slice Instances (NSIs). These definitions are known as Network Slice Templates (NSTs). This work proposes three NSTs for the main 5G usage scenarios created by the IMT-2020: eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communications), and mMTC (massive Machine-Type Communications). Moreover, this work simulates an end-to-end 5G network to analyze whether the NSIs simulated can meet the SLAs (Service Level Agreements) proposed for the eMBB NST and usage scenario. As a result, the NSTs proposed in this work will provide a technical-theoretical reference for the creation of new NSTs related to new 5G usage scenarios and it can guide future research on the simulation of 5G sliced networks.
