For what it's worth, when playing with UDP protocols over residential southern US ISPs I've seen end-to-end packet loss start at less than five percent but then increase rapidly to 90% once a seemingly arbitrary number of packets per second is reached. This happened without saturation of the point-to-point bandwidth and was not connected to size of the packets. Also, it wasn't a crazy test of UDP's limits; it was actually an experiment to see why the AIMD in a real-world data transmission algorithm was flapping. Turns out the 70-90% packet loss would follow the transmit rate down until it reached another seemingly arbitrary point (without regard to rate of decrease) where the loss would return to normal. I did these experiments a year or two ago through a few separate pairs of endpoints, so local malfunctioning equipment can probably be ruled out. ~Chris
