Hi,
It may not be very meaningful on Virtulabox VMs, but in order to evaluate the relative performance of several UPFs, I briefly measured the performance of UPFs.
Note that since User Plane IP Resource Information has been removed in 3GPP Release 16.3, I prioritized the measurement of UPFs that supports FTUP in UP Function Features of PFCP Association Setup Response.
In the figure, CN is written as Open5GS, but free5GC CN was used to measure free5GC UPF that supports User Plane IP Resource Information.
FYI.
BTW, does free5GC UPF have any plan to support FTUP?
