Well this is actually the other way around. First you have your default topology. They you are asked to construct new one based on applied constrains. So you create complete TE coverage and start running end to end data plane probing over all TE paths (say SR-TE for specific example). Once you start collecting the probe results you can start excluding paths which do not meet your applied constraints. And that process continues. To your specific question - It is not that unusual where routers degrade their performance with time and in many cases the traffic is not the cause for it but internal bugs and malfunctions. Best, R.
