- UPF Interconnection. The UPF/SPGW-U is located in the MNO network and needs to be interconnected on the N6/SGi interface to 3PE and/or PCE/PCC.
- UPF Placement. The MNO wants to instantiate a UPF/SPGW-U in a location that is different from their network (e.g. Customer Premises, 3rd Party Data Center)
UPF Interconnection Scenario
Assumptions:
- MNO hosts UPF/SPGW-U in their network.
- MNO provisions all UPF functions.
- MNO may request UPF Interconnection for SGi/N6 interface in a required Metro to 3PE/PCE via APIs (on P2)
- Bare Metal Orchestration Provider and Interconnect Provider expose Data Center Location / Metro to PCEI Enabler via APIs (on P3 and P4)
- 3PE and PCE providers expose Data Center Location / Metro to PCEI Enabler via APIs (on P5 and P8/P7)
- PCEI Enabler may request Bare Metal Orchestration for Distributed UPF via APIs (on P3)
- PCEI Enabler may request Interconnect for MNO UPF (L2/L3) via APIs (on P4)
- PCEI Enabler may request PCC/PCE and/or 3PE Controller to instantiate workload instances for LBO processing via APIs (on P8/P5)
