Re: [OPSEC] Sharing a new draft

[[e-mail]]

Hi Chunchi, Qin, all,

Thank you for sharing this draft. 

Even if I understand that this is a -00, I was expecting the draft to leverage on the long history with the proof of transit work in the IETF. I'm afraid that the current set of use cases are not that appealing to motivate what the document seems (at least to me :-)) to over-sell in the abstract/introduction. 

That's said, I do think that there are aspects of the network path assessment/validation that are worth to be investigated (not only proof of transit, but proof of non transit). These considerations would be more appropriate to investigate in venues such as PANRG, especially that the I-D will have to answer to the same PANRG questions about whether/how internal paths are exposed + how forwarding instructions are signaled to network elements, etc.

FWIW, some comments and suggestions can be found at:

Cheers,
Med

> Abstract:
>    Network path validation refers to a technology that ensures
> data
>    packets to strictly travel along a chosen network path.  It
> aims to
>    enforce data to travel only on the assigned network path and
> provide
>    evidence that the data has indeed followed this path.  While
> existing
>    efforts primarily focus on the control plane, path validation
>    protects and monitors routing security in the data plane.  This
>    document provides a technical definition of the Network Path
>    Validation problem, briefly overviews past efforts, models its
> ideal
>    solution and design goals, and lists out different use case
> across
>    various layers of the Internet.
