Running UPF on a separate, no containarized host #25

Closed ednaganon closed 1 year ago

ednaganon commented 2 years ago

Hello, I would like to run UPF on a separate h similar to the diagram you show here:

Setup-free5gc-on-multiple-clusters-and-test-with-UERANSIM-Architecture

but non containarized, non containerized, so the UPF interfaces are the host interfaces. What configuration changes should I do in smf configuration so that SMF pod could speak with UPF ? specifically the n4 network does not work correctly. Should it be omitted and a nodePort service be created instead? what changes should be made to values.yaml? Thanks, Edna

Hello

You should adapt the N4 and N3 configuration of SMF and UERANSIM to match with the IP addresses of the host of the UPF. That means, this must be connected to the Kubernetes cluster while each of its interfaces must be in the same network as one interface on the Kubernetes cluster (one node of the cluster)

So there is no way to connect towards5gs-helm/free5gc SMF pod to external UPF which is not a part of the Kubernetes cluster? Similar to how N2 is exposed by AMF to an external GNB?

Thanks,

Edna

You can. You have only to make sure that UPF is listening on an IP address which is in the same network as SMF N4 interface. You can reach this for example by having 2 hosts:

At this stage, make sure that the hosts can communicate via their eth0 interfaces. Then, you make the SMF N4 interface using the eth0 of host as master interface (see Helm chart values) and you assign IP3 to it (SMF N4). By choosing IP3 in the same subnet as IP1 and IP2, the SMF and the UPF will be able to communicate.
