Vendor & Operator GNN Implementations
Production Deployments
| Platform | Operators | Use Case |
|---|---|---|
| Google Cloud + NetAI (GraphIQ) | Deutsche Telekom, Vodafone, MasOrange, One NZ | Autonomous network operations, deterministic RCA across OSPF/IP/MPLS/L2/VXLAN/L1 |
| Ericsson | Multiple operators | Uplink interference optimization, Bayesian GNN with confidence intervals |
| Intel O-RAN xApp | — | GNN+DRL connection management (10% throughput gain, 45-140% coverage gain) |
| Nokia Bell Labs | — | Energy-efficient power control in cell-free massive MIMO (<1.2% loss vs. optimal) |
Vendor Research
