Hi, authors of path-vector:

I haven’t seen you addressed IDnits errors raised by Vijay below:

https://www6.ietf.org/tools/idnits?url=https://www.ietf.org/archive/id/draft-ietf-alto-path-vector-13.txt

Please reply to Vijay and confirm whether there are anything missing or open issues which haven’t been closed.

主题: [alto] Shepherd writeup for path-vector (draft)

 

All: I have started the shepherd review of path-vector  The review is below.

The token is with me to do a chair/shepherd review of the draft.  With the semester coming to a close and grading to do, etc., I have reserved the week starting Dec-16 to do the shepherd review of the draft.

 

In the meantime, please go through the draft shepherd writeup and let me know if I have erred anywhere.

 

Thanks,

Shepherd writeup for draft-ietf-alto-path-vector-13

1. Summary.

The document shepherd is Vijay K. Gurbani, and the responsible area director is Martin Duke.

The document is a Standards Track document, targeted as a Proposed Standard.  The WG has chosen the requested publication type since this draft extends the base ALTO protocol in a normative manner.  Specifically, the document seeks to extend the base ALTO protocol (RFC 7285) to provide the concept of "Abstract Network Elements" (ANE).  ANEs are an abstraction of physical network components --- routers, etc. --- that handle (switch) packets.  An application whose performance may be impacted by a particular traversal path in the network may wish to consult the ANEs to determine an optimized path to the destination.

This draft is a major conceptual advance in the abstractions provided by the base ALTO protocol.

2. Review and consensus.
This work is mature.  It started off as an individual submission in March 2015, and was adopted as a WG deliverable in May 2017.  A detailed review of this draft was provided early on by Sabine Randriamasy [1,2,3] shortly after it was adopted.  Version -04 was further reviewed by Danny Perez [4] and Qiao Xiang [5] in 2018, and the work progressed appreciably between 2018 and 2019, resulting in the release of -09 in November 2019.

A WGLC was initiated on Sep-28-2020, and a review was provided by Qiao Xiang [6] and Luis Contreras [7] on version -11.  Version -12 included the comments from Qiao and Luis, with version -13 following with some minor revisions.

Earlier versions of path-vector have been implemented (without the integration of unified-props); the implementation was used in a super computing conference demonstration for OpenFlow-based networks [8].  The latest version of path-vector is being implemented and will be open-sourced on GitHub [9].

The shepherd has an action item to review version -13.

3. Intellectual property
All of the authors have confirmed with the shephered that they are not aware of any IPR filed with respect to the draft.

4. Other points
IDNits reports 1 error, 7 warnings, and 2 comments.
