Jeffrey,

When a UE moves from gNB1 to gNB2, I thought the End Marker from gNB1 is sent to UPF (instead of being sent to the gNB2 as described in you draft). Is it correct?

For the distributed UPFs, when a UE moves from UPF1 to UPF2, UPF1 and UPF2 might have different public IP addresses. How does PE be able to handle the End Marker? Is it necessary for PEs (which are on N6 interface) to even care?

Thank you.
Linda
