Re: [nvo3] WG Adoption Call - draft-dmk-rtgwg-multisegment-sdwan (04/10/24 - 04/26/24)

[linchangwang <[e-mail]>]

Hi WG,

This draft allows the Cloud Backbone to connect multiple segments of SD-WAN without the need for decryption and re-encryption by the Cloud GWs.
This improves efficiency and enhances security.

The solution seems to be reasonable, so I support this adoption.

I have two questions and I recommend making modifications after adoption:

1.       In Figure 4, there are two instances of "Type = Multi-seg-SDWAN_subType3".

Should one of these be "Type = Multi-seg-SDWAN_subType2"?

Additionally, if these two Multi-Hop Transit SD-WAN types are used, I suggest providing further detailed descriptions in subsequent sections.


2.       Figures 8 and 9 are intended to illustrate single-hop and multi-hop encapsulation, but the actual figures do not show the difference between single-hop and multi-hop.

I suggest modifying the descriptions in the figures. Additionally, Figure 8 has a UDP port number, while Figure 9 does not.

Best Regards,
Changwang

Hi,

This email begins a 2 week WG adoption poll for the following draft: draft-dmk-rtgwg-multisegment-sdwan-07 - Multi-segment SD-WAN via Cloud DCs (ietf.org)<https://datatracker.ietf.org/doc/draft-dmk-rtgwg-multisegment-sdwan/>

After the draft was presented at IETF 119, the chairs did a poll of the draft, and here are the questions and results:

  *   "Do you think the multi-segment SD-WAN as described in the draft is a use case that the IETF should work on?"
yes: 20 no: 9 no_opinion: 33 total: 84

  *   "Do you support adoption of this work in RTGWG?"
yes: 9 no: 9 no_opinion: 25 total: 92

There is currently one IPR disclosure of this draft: IPR disclosures (ietf.org)<https://datatracker.ietf.org/ipr/search/?submit=draft&id=draft-dmk-rtgwg-multisegment-sdwan>
Authors, please respond to the list indicating whether you are aware of any IPR that applies to the draft.

The draft proposes a solution which extends GENEVE, so also copying NVO3 WG. If you don't think the draft should be adopted in RTGWG, please voice your opinion.
