Re: your comment on EH insertion.

This point is not applicable; a new version of srv6-mobile-uplane 
( is
published making SRv6 encapsulation the default.

Dear folks,

A new revision of SRv6 Mobile User Plane draft has been submitted to IETF.

I’d present brief summary of the updates, but the agenda seems already full so 
that it is uncertain I can do that.

So let me share the summary of update on the -01 version here.

A Big progress is that the draft supports interworking with GTP over IPv6 in 
addition to GTP over IPv4.
And we have made change SRv6 function to IPv6 encapsulation with SRH instead of 
SRH insertion by default.

Another changes have been made. 5G architecture in 3GPP is shown as a reference 
architecture, as the discussion on the list many people ask SRv6 applicability 
for 5G. As the result, many terminologies are aligned based on the reference.

You can see many improvements in terms of readability, especially on packet 
flow explanations. I hope that many of us understand how SRv6 works for the 
deployment cases described in the draft.

Pablo has contributed those significant part of progresses and improvements. 
He's now onboard as a co-author of the draft.

Best regards,

  This document discusses the applicability of SRv6 (Segment Routing
  IPv6) to user-plane of mobile networks.  The source routing
  capability and the network programming nature of SRv6, accomplish
  mobile user-plane functions in a simple manner.  The statelessness
  and the ability to control underlying layer will be even more
  beneficial to the mobile user-plane, in terms of providing
  flexibility and SLA control for various applications.  It also
  simplifies the network architecture by eliminating the necessity of
  tunnels, such as GTP-U [TS.29281], PMIP [RFC5213], Mac-in-Mac, MPLS,
  and so on.  In addition, Segment Routing provides an enhanced method
  for network slicing, which is briefly introduced by this document.
