Hi Satoru, Few questions in-line -- Uma C.

Following draft exhibits how service chain can be done by SRv6: https://tools.ietf.org/html/draft-xuclad-spring-sr-service-chaining-00 [Uma]: I presume this is on N6 interface once de-capsulation is done at eventual UPF. So can I say this is one more alternative to NSH ?? Do you see any relevance of this in any other interface? ... > Also you show IPv6/SRv6 nodes in those slides. Are the UPFs ‘overlaid’ on > IPv6/SRv6 nodes? > Are these UPFs VNFs? Or are UPFs implemented on IPv6/SRv6 nodes? > When you see UPF specifically it should be controlled by SMF through N4, they are not the UPFs. But you might see them as UPFs if a SMF doesn’t control them directly but the SMF can put the sessions to it through some other means. [Uma]: Didn't quite understand. Are you referring southbound interface like PCEP here? _______________________________________________ dmm mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmm
