How it Works
The functionality of Multiple cnSGW feature involves:
-
Single UPF has multiple N4/Sx interface associations with SMF/cnSGWs.
-
There's no slicing of configuration in UPF per individual SMF.
-
Cumulatively, a maximum of four peers—combination of cnSGW/SMF or individual cnSGW/SMF as per the need—are connected to a single UPF.
-
Individual N4/Sx association release purges sessions of the impacted peer.
-
UPF redundancy works seamlessly.
-
All cnSGWs paired with a UPF is associated with a single user plane service.
