Edge-Computing

Edge computing in telecommunications places compute, storage, and application execution close to users and devices — at cell sites, regional points of presence, or on-prem enterprise locations — rather than only in distant hyperscale data centres. The goal is to reduce end-to-end latency, limit backhaul load, satisfy data residency, and enable real-time applications (AR/VR, industrial control, V2X, video analytics) that are impractical with 50–100 ms round trips to central clouds. In 5G, edge is tightly coupled to the user plane: a local UPF on N6 breakout forwards traffic to an edge data network (DN) hosting MEC applications without hairpinning through the operator’s core hub.
