Deploying opensource 5gcore on AKS

Avishek Arora 0 Microsoft Employee

I'm trying to deploy 5G core function using open source 5g cores e.g. (Open5GS, Free5GC and OpenAirInterface).
I'm doing this as part of research, some old article says that you cannot enable SCTP in aks nodes.
is that still holds??

https://learn.microsoft.com/en-us/answers/questions/1182840/sctp-network-protocol-not-supported-on-aks-nodes

If yes, is there any alternatives?

Please let me know, i've already spend few weeks into this matter.

Hello @Avishek Arora

Yes, it is still true that SCTP is not supported on AKS nodes. This is because the SCTP protocol is not widely used and is not a part of the standard Kubernetes networking model.

However, there are some alternatives that you can consider:

Use a different protocol: If possible, you can consider using a different protocol that is supported on AKS nodes. For example, you can use TCP or UDP instead of SCTP.

Use a different container orchestration platform: If SCTP is critical for your application, you can consider using a different container orchestration platform that supports SCTP. For example, you can use OpenShift or Docker Swarm.

Use a sidecar container: You can use a sidecar container to handle SCTP traffic. The sidecar container can run on the same pod as your application container and can handle the SCTP traffic. This approach requires additional configuration and management overhead, but it can allow you to use SCTP with AKS.

I hope this helps you find a solution for your research project. Let me know if you have any other questions or concerns.
