Hi Tony,

Yes exactly. Is this good ?

I think that is pretty obvious to everyone. Not sure why you keep repeating
it in each mail :)

> If all of your links are congested, then TTE will not help you.

That is not the point.

The point is that during TTE provisioning (enabling TTE on a per node or
per interface of the node basis) alternative links may not be congested.
But during unexpected load there can be congestion on backup paths and
nodes executing TTE will have zero knowledge about it. They will simply
redirect part of the traffic only hoping that other paths perhaps are idle
enough.

> There is nothing that can, except more bandwidth and I see no benefit to
even discussing this situation.

Well to start with you are assuming that end to end TE is very badly
provisioned as if it would be built correctly all available paths can be
utilized relaxing the need for any local per node blind spread.

Kind regards,
Robert
