Something also to consider is that many of the peers (routers) on that route probably are configured to give BGP operations priority over ICMP traffic (ping) traffic. So if it is indeed busy as Dan pointed out, then more BGP overhead exists. If you get a hop or two which happens to be very busy with route announcements or other broadcasts it is plausible that what you see from a 40 byte ping packet in terms of latency could be a substantial departure from what the actual in-game latency will be.
That makes absolutely no sense. If they had BGP overhead from announcements (besides memory overhead locally to that specific router), I'd see the route flapping. BGP can't keep announcing prefixes over and over, they would get dampened. Most of the time, high latency from IX's is due to congestion/oversubscribing of circuit(s)/hot potato routing/equipment misconfiguration. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
