Hi Tony, > then TTE would simply shift load around and drop things elsewhere.
Yes exactly. Is this good ? > TTE cannot create bandwidth. 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
