Local Breakout Edge

Instead of sending all data through a central hub (which can get crowded and slow), local breakout edge allows data to exit the network closer to where it's needed. This means faster and more efficient internet connections, especially for things like video calls, online gaming, and smart devices.

What is Local Breakout Edge

A Local Breakout Edge is an advanced 5G Standalone (SA) core setup – also known as a Telco Edge, withan on-premises User Plane Function (UPF) integrated with the Central core. The local UPF instance allows the data to exit to an application hosted by an Edge Cloudor to 5G devices in the area. The UPF is associated to a data network name (DNN) pointing to data networks that can be accessed via the UPF (e.g., an Edge Cloud, local data networks and the Internet).A 5G device then needs to be configured with the local UPF’s DNN to keep the data locally.

Technical Specifications

For distances of approximately 500 km between the Local Breakout Edge and the central 5G Stand-Alone core:

One-way delay for device-to-device: ~15 milliseconds
One-way delay for device-to-device: ~11 miliseconds
Data rate: Typically up to 10 Mbps

Improved from 4G

4G networks typically have latencies around 20-30 ms. URLLC in 5G reduces this to just 1 ms - that's 20-30 times faster! Moreover, 4G networks couldn't guarantee the ultra-high reliability that URLLC provides.

Local Breakout Edge's role in 5G

Telco Edge for Low Latency

A Local Breakout Edge takes benefit from an on-premises UPF instance to keep traffic at the edge of the network and reduce latency.
