I'm not trying to push any particular algorithm, we already have some proposals. My intention was only to suggest that we not disregard solutions too aggressively. The argument that there are too many queues in one routers implementation of a punt path, or there are so few or none that one can't tell IS-IS from other traffic early enough doesn't mean that one couldn't consider what *would* be required for a simple solution to be viable. If a simple solution is elegant enough then perhaps market forces start coming in to play and the cost to implement isn't actually that high.

In any case we already have a couple proposed semi-solutions and during the meeting it seemed to be agreed that people would write some code and collect some data at this point.
