If I am not mistaken, the true "benefit" to 95% billing is that it allows the provider to charge for bits they never delivered. The average will skew on a burst of traffic (>5% of the average) and you pay for it as if you had averaged that level the entire time. It seems like quite an irrational settlement model. Why not simply bill for every bit that crosses your network? There certainly is a per-bit cost. I cannot, off the top of my head, think of another telecommunications industry that relies on a system of averages for settlement. It speaks pretty clearly of how immature the Internet industry really is. Or maybe not. Perhaps the electrical suppliers here in California should bill in the 95th percentile, and cite the Internet as a rational example. Regards, James
