A small 5G core for labs
A complete 5G core network in four core processes — DMF (AMF + SMF), DPF (AUSF + UDM + UDR + PCF), NRF, and UPF — plus optional NSSF and SMSF when you need them. It runs the full golden path on your laptop, driven by a docker-compose lab and a gNB simulator.
Start here
What dflux TinyCore is, the network functions (core + optional NSSF/SMSF), and the 5G golden path it runs.
ExploreQuickstart
Install the required NFs (plus optional NSSF/SMSF), run them natively, and register a UE in about ten minutes.
ExploreMental model
How DMF, DPF, NRF, and UPF fit together, and which 3GPP interfaces are real vs in-process.
ExploreHands-on
Drive a gNB simulator end to end: registration, 5G-AKA, a PDU session, and user-plane traffic.
ExploreHow-tos
Day-to-day tasks: provision subscribers, connect a gNB, configure DNNs, persist state, observe.
ExploreLook it up
Every CLI flag, the default ports and pools, the metrics, the subscriber schema, 3GPP coverage.
