5G network slicing lets service providers deliver tailored connectivity—ultra-low latency, high bandwidth, or massive IoT—via isolated virtual networks across RAN, edge, transport, and core. Success hinges on cross-domain orchestration, automation, and multi-vendor, API-driven architectures. Transport slicing leverages segment routing, SDN, and QoS policies; core slicing uses containerized 5G functions orchestrated with Kubernetes. Cisco’s Crosswork and NSO platforms enable dynamic provisioning, assurance-driven management, and rapid deployment via slice templates, supporting scalable, cost-efficient enterprise services.
