Network slicing is one of the vital concepts in 5G networks. Isolated parts of the network can serve the needs of specific traffic types, applications, or users, guaranteeing various QoS parameters, including speed, latency, and security. Traditionally, the network traffic was aggregated regardless of its requirements. With network slicing, specific applications, especially latency-constrained, will be better served in the infrastructure according to the Service Level Agreements. Deutsche Telekom and Ericsson announced a proof of concept implementation of global 5G end-to-end network slicing for latency-critical enterprise applications with guaranteed Quality of Service. The technology is becoming more widely executed and an exciting reality enabled by new networking technologies.
