Use Cases
FlowLens covers the full spectrum from simple observation to carrier enforcement.
| Pattern | Plugins | Who uses it |
|---|---|---|
| Visibility-only | vpp-ndpi + vpp-exporter | Network engineers adding observability |
| ISP billing | vpp-ndpi + vpp-ipfix | ISPs generating per-subscriber usage reports |
| Enterprise edge | vpp-ndpi + vpp-policy + vpp-exporter | Enterprise policy enforcement + Grafana |
| 5G UPF | GTP-U decap → vpp-ndpi → vpp-policy | MNOs implementing PFCP-triggered detection |
| SD-WAN CPE | vpp-ndpi → vpp-sdwan-steer | App-aware WAN path selection |
| Carrier enforcement | vpp-ndpi + vpp-gobgp-flowspec | BGP FlowSpec from upstream PE |
- ISP / Telco — Application-aware traffic management — passive visibility, IPFIX billing, and BGP FlowSpec enforcement.
- Enterprise Edge — Per-application policy enforcement with Grafana visibility — no separate DPI appliance.
- 5G UPF — Application detection in the 5G user plane — PFCP-triggered classification for PCC rules.
- SD-WAN CPE — Application-aware WAN path selection with BFD-driven automatic failover.
