You can read it later on this September. See https://portal.3gpp.org/ngppapp/CreateTdoc.aspx?mode=view&contributionUid=SP-170743 > > [KB] I think your document needs to separate out 3 architectures: one for 4G > - SGW/PGW; one for 4G - CUPS; and one for 5G - UPF. If you mean SRv6 Mobile Uplane draft, it is already a WG document, not my draft. So I’d collect opinions on this from WG. I’m sorry for that. As a co-author of the draft, I’m afraid I disagree. SRv6 Mobile Uplane draft specifies SRv6 functions for mobile user plane, which should be architecture agnostic. > > [KB] I am also still not clear if the blue icons (which I think represent > IP/MPLS nodes) in your slides are included in SRv6 architecture or not. I put some text what those icons indicate. Please find them in the slides. The blue icons represent IPv6 or SRv6 node.
