Thanks to Loa for reminding me of the questions. Actually my question is more fundamental. The 3GPP Mobility Management Function manages the IP address assignments to UEs. Traffic from UEs are tunneled by GTP tunnel between the eNB and UPF. Many UPF has NAT, so the IP network might not see the UE's actual IP addresses.
Question 1: is draft-mpmz-bess-mup-safi managing the IP address from UPF? Or the actual UEs' IP addresses? Question 2: If it is the IP addresses from the UPF, many flows from different UEs are aggregated to one IP. What the BGP extension for Mobile User Plan do? Thank you very much.

The audio was bad, but I think Linda asked "VPN 3GPP and and VPN6, uses totally different address, how are they inter-worked?" I could not hear your answer, can you please repeat here? Wim asked about the relationship to 3GPP. I think your answer was that since you are not changing anything in the 3GPP specifications there is no problem. That might be correct, but I think it would be prudent to let 3GPP know what we are doing. /Loa -- Loa Andersson email: [email protected] Senior MPLS Expert [email protected] Bronze Dragon Consulting phone: +46 739 81 21 64 _______________________________________________ BESS mailing list [email protected] https://www.ietf.org/mailman/listinfo/bess
