Solutions for Traffic Isolation in 5G Infrastructures Using Network Slicing Techniques

Network slicing techniques are paramount for the operation of commercial networks, as the 5G networks community widely accepts them. These techniques allow the creation of multiple virtual networks on top of a physical network to isolate the traffic and guarantee the applications' requirements. These will allow the deployment of more tailored use cases, such as disaggregated services and specific highly consuming multimedia services. Therefore, several network slicing techniques are proposed in this paper to obtain traffic isolation in a 5G infrastructure. Specifically, edge and cloud architectures and alternatives to traditional network stack protocols are considered in the proposed solutions when slicing their virtual networks. Moreover, this paper describes which use cases are the most suitable for each proposed network slicing technique.
