Hi Folks At the risk of making a possibly naive request, could someone point me to data on ISP network performance (routing stability, packet loss, latency) ? I am primarily interested in the first metric, and am trying to understand the relative stability of large, _well-engineered_ ISP networks. In other words, with what degree of confidence can I predict the IP-level path between two PoPs of a large ISP. Please note that I am not getting into the general Internet performance here. Somehow I get this feeling that the answer would be a fairly large...it depends ! It would be useful to understand the influencing factors as well. Thanks. Rajesh. -- Rajesh R.
