How it Works
cnSGW-CSMF (CNF) can be deployed in a geographic redundant manner to provide service across a catastrophic failure, such as data center failure of a rack hosting a cnSGW-CSMF cluster.
Each CNF instance service registers with NRF and S11/S5 for DNS entry for MME/SGW. Local HA redundancy allows instance to achieve rack level redundancy in addition to K8 cluster level failures within same data center or handle locally within same K8 cluster if failed containers are per Type-2 < n.
where, n is a value. For less than 50% of container failures, HA should handle the failures. For more than 50% of container failures, GR switchover is triggered.
