a fellow researcher wants
to make the case that in some scenarios it is very important for a network operator to be able to specify that traffic should *not* traverse a certain switch/link/group of switches/group of links (that's true right?). Could you give some examples? Perhaps point me to relevant references?
if so, why? security? congestion? other? but is it common? and, if so, how do you do it?

In the wireless backhaul space I¹ve seen carriers that would prefer a circuit to go down rather than take the long path on a ring between tower and switching center. I assume they are concerned with some sort of latency requirement. We used RSVP-TE with link coloring as the solution. -Steve
