Chairs,

I believe that we have two independent requests for a comparison of the benefits of SRv6 over SR-MPLS in the network programming draft.

A comparison of the benefits of SRv6 over SR-MPLS is one thing that could possibly be discussed if there is interest from the WG.
E.g. to help network provider make a choice, or in the context of "beyond SRv6" to help the WG identify the benefit/cost analysis of existing solutions and what we want to achieve with new/extensions to SR data planes.

But why do you think that this would belong to draft-ietf-spring-srv6-network-programming?

Thanks,
--Bruno

Ron,

If you want to discuss your analysis please let's do so in a separate email thread out of the context of the Working Group Last Call of draft-ietf-spring-srv6-network-programming.

As I said before: draft-ietf-spring-srv6-network-programming is a Standards Track document and this topic is not about any standardization, hence out of scope of this document.

Same applies to other content (e.g. illustrations) that was formerly in network programming and we moved to a separate draft since it was not standardizing anything at all and was merely informative.

Thanks,
Pablo.

Pablo,

RFC 8354 reinforces my analysis in https://mailarchive.ietf.org/arch/msg/spring/3WGuQumIfcmH281nwq3s9Un6raI<https://urldefense.com/v3/__https:/mailarchive.ietf.org/arch/msg/spring/3WGuQumIfcmH281nwq3s9Un6raI__;!!NEt6yMaO-gk!SolNvh35q4NS-PTVWOxXAzbTnMHltfvPWi_OSjhMYkmm_NucR6imYrrLvc35Kat6$>. Are you saying that you agree with this analysis?

                                             Ron

Ron,

SPRING has already done this work and documented the SRv6 use-cases in RFC8354 before progressing with the SRv6 standardization.

Further on, draft-ietf-spring-srv6-network-programming is a Standards Track document.
I fail to see how a cite from RFC8354 or any other text on "SRv6 vs SR-MPLS" standardises anything at all.
Note that we have already removed text from draft-ietf-spring-srv6-network-programming (e.g. illustrations) because it was not standardising anything.

Thank you for the suggestion,
Pablo.

Pablo,

Would you consider adding a short section to the draft explaining the relative advantages of SRv6 over SR-MPLS? This section would explain why an network operator would deploy SRv6 instead of SR-MPLS.

                                                                                         Ron
