Hi Pablo,
Would you please explain the benifts of the flavors? Why do you want to do so, not \
just you can do so. For USP and USD, when we only use encapsulation, in which \
situation the destination only do USP, but not decapsulating the outer header?
Two more questions:
1. draft-ietf-spring-srv6-network-programming says the PSP, USP and USD flavors are \
variants of the End, End.X and End.T behaviors. But the example illustrated in \
NET-PGM Section 2.8.1 is DT4. 2. The instructions for PSP and USP are just pop the \
SRH, don't we need to update the NH in the outer header accordingly? for exmaple, SRH \
is inserted when encapsulating a packet at an ingress node, and only SRH is inserted, \
the NH of the outer IPv6 header is SRH, and the NH in the SRH is the upper \
protocol(the type of the original packet). When the SRH is poped in this example, the \
NH of the outer header is still SRH, don't we need to update it?
Best Regards,
Zhenqiang Li

draft-ietf-spring-srv6-network-programming-03.txt Zhenqiang, Ron,
The PSP/USP/USD flavors are not -and have never been- related to SRH insertion.
One example for the PSP behavior is the first use-case that Wang described in his \
email. This same use-case is also captured in the companion illustrations document \
for NET-PGM Section 2.8.1. [1] together with a detailed packet flow.
Note also that the example that I provided in my previous email is for the USP \
flavor, which is one of the two that you are asking for. The decapsulation can only \
be achieved with the USD flavor which is different.
I believe that the technical aspects associated with PSP/USP have been addressed.
Cheers,
Pablo.

Hello Pablo,
Without SRH insertion, PSP and USP are not needed. The example you give is \
decapsulation, not SRH pop. I can not imagine the scenario that will use PSP or USP \
without SRH insertion. We need illustration to keep them in the draft.
Best Regards,
Zhenqiang Li

draft-ietf-spring-srv6-network-programming-03.txt Hi Zhenqiang,
Can you clarify what is the issue with the PSP and USP flavors and how it is related \
to SRH insertion?
For example USP flavor removes the SRH at the last segment (the final destination of \
the IP packet), before proceeding with the upper layer header processing.
Cheers,
Pablo.

Hi Pablo and all,
Thank the authors for their efforts and quick reponse to the discussion in the list.
Since the SRH insertion parts are now removed from the base srv6 network programming \
draft, are the PSP and USP flavors appropriate to stay here? They do the SRH POP \
action.
Best Regards,
Zhenqiang Li

Hi all,
We have just posted the split of SRv6 Network Programming.
The SR endpoint and transit behaviors that perform SRH insertion are now under a new \
individual draft (draft-filsfils-spring-srv6-net-pgm-insertion). This revision does \
not contain any other update.
As mentioned last week, throughout the rest of the week we will push another update \
with a few functional updates (e.g. NH=59).
Thank you,
Pablo (on behalf of the authors).
