Re: [Teas] I-D Action: draft-ietf-teas-rfc3272bis-11.txt

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
