Pablo, et al,

 

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

 

In Section 3.1.3, you stated that SRv6 offers Load b= alancing among VNFs, does it require the head node to be aware of all the i= nstances to make it possible? If the Mobile operators manage their VNFs tra= nsparent 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 SR= v6 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 diff= erent from the user’s mobile network provider, then this automaticall= y switch over won’t happen, correct?

 

 

Thank you

Linda Dunbar
