And DGD based on packet counts IMO is an extremely simple thing to do, I discussed it recently with you.

(If I recall correctly and / or re-read the appropriate thread correctly.)

What you were talking about doing was pinging (of sorts, be it ICMP, testing connections, sending layer 7 traffic, etc.) destinations out side of your upstream gateway. Correct?

If something like this was present in-kernel the world would be a better place.

I agree that if there was a way for the kernel to handle this the world would be a better place. However, I think it silly to expect the kernel to do this.

Well let me take a moment to be sure we are thinking the same thing. You want the kernel to be able to realize that one route through a given default gateway is no good for a given destination and use a different default gateway even though the kernel can reach other destinations through the first default gateway? In other words, if the kernel can not reach microsoft.com through ISP1 it should use ISP2 despite the fact that it can reach google.com through ISP1?
