I'm not sure what you are saying regarding filling up an OC3 with NTP, but
i do know you can calculate simple latency I believe, measurements from
normal NTP  = but strategically analyzed from remote sources and correctly
configured i.e. all s/1 or s/2 with drift.


I wont' say I'm the expert at this, I'm the bb wiretap guy :), not the ntp
latency guy.......but I've been around a bit.
