HI Kalyani, > The adaptation from GTP to IP has to happen somewhere, either in the radio > node or in the UPF. I guess when you say from “adaptation from GTP to IP”, you mean to say GTP-U decapsulation of the user-plane IP packet for handling it by other protocols and for forwarding it on

Kalyani, steering traffic on N6 in between a correspondent service (Data Network, DN) and a mobile's UPF, and this is what I referred to, does not require N6/Gi-LAN functions, just routing policies in the transport network. This can be policies at the N6 edges, means at the UPF side and the DN

Hi Satoru, I saw in your presentation you made in Singapore at 5gangip side meeting that SRv6 needs SDN controller to put SIDs to the nodes with its functions. Can you elaborate on that? My concern is that I wonder if 3GPP supports SDN, especially what would be the south bound interface?

Re: [DMM] [Ila] [E] Re: Fwd: New Version Notification for draft-herbert-ila-mobile-00.txt

Sri: Even though N3 is shown for 5G and S1-U for 4G, my understanding is that there are commons sub-layers in the protocol stack that are common to both 4G and 5G radio accesses that could be re-used. The adaptation from GTP to IP has to happen somewhere, either in the radio node or in the UPF.

Re: [DMM] [Ila] [E] Re: Fwd: New Version Notification for draft-herbert-ila-mobile-00.txt

Marco: There are 2 kinds of non-mobility nodes/functions: - One set is what you are referring to as N6 based functions, also called Gi-LAN functions that could be chained to PGW/UPF on Gi/SGi/N6. - The second set of functions are related to transport (IP/MPLS) over which

Hi Kalyani, My take on your latest feedback: > I think you are talking about 2 features: one for mobility that needs the > database; another > for non-mobility state transfer between user plane nodes (not necessarily > mobility nodes). True, control plane impact on data plane can be on N3, N9
