AMF separated

[Evanlin1224]

hello, @s5uishida I want to separate AMF from open5gs as VM1, and others NFs as VM2. My idea is modify install/etc/open5gs/amf.yaml , right?

Hi @Evanlin1224

Yes.

In addition, I think it is necessary to change the loopback addresses (127.0.0.x) of the SBI (Service Based Interface) of each NFs to make it a network that can communicate with the outer AMF.

@s5uishida thanks I will try it!

Hi,

In such a case on VM1, only AMF will be running and other components of Open5GS(SMF, UPF, BSF, etc.) should be manually stopped? And on VM2, all components except AMF should be running? Could you please confirm it. Thanks

Best regards, Sadrones

Hi @sadrones

In that case, I think that each NF should be run on each VM as follows.

• VM1 - amf
• VM2 - nrf smf ausf udm udr pcf nssf bsf (and upf?)

In addition, I think that NRF should be run first.

@s5uishida , Thank you so much for your prompt response. I need to get more clear on the topic. As you said VM1 - AMF, I got it. But, my question is when you install the Open5GS, it has all the components together and they run by default. In that case, on VM1 should I stop all other components except AMF or is there any other mechanism? Same question for VM2: should I stop AMF from VM2 while running other NFs?

Sorry to ask you again but I need the clarification.

Best regards, Sadrones

Hi @sadrones

My configuration is just an example.

For example, each Open5GS NF can run on a different VM. Basically, I think that each NF could be flexibly run with the following set.

• install/bin/open5gs-xxxd
• install/install/etc/open5gs/xxx.yaml

There is no need to run all NFs on the same VM at all. I think Open5GS can be flexibly configured according to your environment.
