Hi Robert,
We are formulating our request for increased measurement limits for our
experiment. To help with our planning, what would be a reasonable rate of ping
measurements from an single anchor to different targets? Specifically, we need
to ping 1M targets, with each measurement involving three pings, so to complete
the experiment in one day, this would translate into (1M*3 = 3M pings)/(24*3600
secs in a day) = ~35 pings per sec. This would obviously be nothing for a
regular server, but would this be an issue for an anchor? (The rest of our
measurement limit needs would flow from this data point).
Thanks,
Misha
