Request for clarification on 4G-core-MME-loadbalancer deployment

[Ghazalmn8]

Dear Christopher,

I am writing to seek your guidance regarding the deployment setup in this Repository.

Recently, I attempted to run an open5gs core network with two MMEs using your deployment templates. I was able to successfully connect UE via USRP when testing, however I faced issues when attempting to use ipvsadm for load balancing between the MMEs.

In reviewing your configurations, I noticed the inclusion of ipvsadm commands in both the Helm chart and Docker compose files. I am unsure of the intention behind using ipvsadm in both places. Additionally, the iptables rules specified in the Docker compose file are unclear to me regarding their purpose.

Overall, I found the documentation lacking in properly explaining the architectural design decisions and intended workflow of the deployment. This led to confusion in properly standing up and testing the network.

I would greatly appreciate if you could provide some guidance to help clarify:

The reasoning behind using ipvsadm in both the Helm chart and Docker compose
The purpose and necessity of the iptables rules defined
Suggestions for properly documenting your deployment setup to prevent others from facing similar issues
Your insight would be extremely helpful for my learning. Please let me know if you have any time to provide feedback or pointers around optimizing the usability and understandability of your repository.

Thank you in advance for your consideration.

Regards
Ghazal
