> Not all of the routers in question (the ones that crash, block packets > or otherwise misbehave) are provided by ISPs The ones that block and misbehave are the bigger problem. The ones that crash are less of a problem and I think they are less common. Certainly if they were common then people would be abusing the flaw routinely. Similar end users tend to grasp "if it keeps crashing blame the supplier". When stuff just mysteriously doesn't work it is a whole lot more problematic. I think however Sally Floyd had it right and Alexey has it wrong (as does Davem). If you turn it off on a retransmit then you provide an immediate incentive for everyone on the web server end of the business to fix their network. Especially if you turn it off for second retransmit. That will cause faulty ECN handling sites to feel "a bit slow" and we know from marketing data that web site performance is crucial to customer base. A three or four second delay getting a page up translates into dramatically reduced hit counts.
