Excellent. Thanks. Looking forward to seeing your thoughts.

 

Best,

Hi Adrian

 

I reviewed the latest revision 11 and it looks excellent and well done by all the feedback from WG thus far.

 

I am still in the process of building some minor updates as it relates to design and architectural flavors of TE deployments as within Verizon we have a variety of deployments and the goals are different in each environment public internet or private MPLS / SR or internal implementations.  

 

The major difference in implementation is the goal of congestion control and avoidance versus traffic flow bandwidth management as the goals and objectives are very different and there is also as well a mixture hybrid of both concepts as well.  Also some thoughts on what works well and what does not and the critical component of overall good network capacity planning and based on the congestion control or avoidance design that if your have enough of capacity for high bw flows the amount of TE is minimal if any.  Also idea of leveraging IGP based metrics to provide bandwidth delay framework which eliminates that function to be provided by TE concept framework which also limits the amount of TE necessary.  

 

I should be completed in about a week maybe less.

 

Kind Regards 

 

Gyan

Yes. Let’s set end of April for everyone. Then I can do an update and then the chairs can last call it.

Hi Adrian 

 

End of April works for me better as well if you are good.

 

Thanks

Hi Adrian 

 

I will plan to complete the review by tomorrow.

 

Sorry for the delay.

With this version I have filled in the remaining TBDs:
- small section on intent-based network
- small section on multi-layer TE (thanks, Lou, for the suggestion)
- change log from 3272

As far as I'm concerned this document is complete modulo review comments.

It *really* needs review, but I can't force you!
Maybe you can look at the sections of special interest to you?
Maybe the original Design Team could take another look?

Otherwise: time for WG last call?

Thanks,
Adrian

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Traffic Engineering Architecture and
Signaling WG of the IETF.

        Title           : Overview and Principles of Internet Traffic
Engineering
        Author          : Adrian Farrel
        Filename        : draft-ietf-teas-rfc3272bis-11.txt
        Pages           : 91
        Date            : 2021-04-07

Abstract:
   This document describes the principles of traffic engineering (TE) in
   the Internet.  The document is intended to promote better
   understanding of the issues surrounding traffic engineering in IP
   networks and the networks that support IP networking, and to provide
   a common basis for the development of traffic engineering
   capabilities for the Internet.  The principles, architectures, and
   methodologies for performance evaluation and performance optimization
   of operational networks are also discussed.

   This work was first published as RFC 3272 in May 2002.  This document
   obsoletes RFC 3272 by making a complete update to bring the text in
   line with best current practices for Internet traffic engineering and
   to include references to the latest relevant work in the IETF.
