Pablo, et al,

Your draft assumes that UE to gNB is with the SRv6 instead of 3GPP's GTP? If you can't convince 3GPP to replace their GTP, what kind of scenarios will deploy SRv6 from UE -gNB-UPF?

In Section 3.1.3, you stated that SRv6 offers Load balancing among VNFs, does it require the head node to be aware of all the instances to make it possible? If the Mobile operators manage their VNFs transparent of the UE, can SRv6 still offer load balancing among VNFs? If Yes, How?

In Section 3.2.1.1.  You stated the value of SRv6 can automatically connects a user to its home wireless network when the user enters the house. Does it require UE be the SRv6 head node?
Most likely the home access network provider is different from the user's mobile network provider, then this automatically switch over won't happen, correct?


Thank you
Linda Dunbar
