You can read it later on this September. See https://urldefense.proofpoint.com/v2/url?u=https-3A__portal.3gpp.org_ngppapp_CreateTdoc.aspx-3Fmode-3Dview-26contributionUid-3DSP-2D170743&d=DwIFaQ&c=udBTRvFvXC5Dhqg7UHpJlPps3mZ3LRxpb6__0PomBTQ&r=IdiSODh8aDRjdCeGgd9MznLHMYKgKcs_YSwXBDiaofh47oilzaXYRYETcBynUdpT&m=A4gJxIMQxDhuwbITGRX_eHAfWF36yy799w_bFx5TDFc&s=ZNR28OMiy-m_kDk3BNz7y8KuA-bfdBBr2HeRt8WQl5c&e [KB] Thank you > > [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] Sections 7.2, 7.3 refer to 3GPP terminology like eNB, SGW, PGW. My comment was suggesting that you include 5G terminology and CUPS terminology as well so it is clear how your proposal can be used in various scenarios. > > [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. [KB] Seems like the IPv6/SRv6 nodes do not interact with SMF. Is that the intent? Cheers, --satoru _______________________________________________ dmm mailing list firstname.lastname@example.org https://www.ietf.org/mailman/listinfo/dmm
