Hi Randell,
I didn't follow the whole discussion but regarding LEDBAT we have a TARGET
delay of max. 100ms. That means you can choose a smaller one. We've chosen
100ms as a max as there is an ITU recommendation that 150 ms delay is
acceptable for most user voice applications and we wanted for sure stay below
that.
100 ms + 75ms speed of light delay across the US (or equivalent across
Europe, for example) + 100ms at the receiving end....
Of course, it's even worse between continents, even without broken networks.
Not so nice....
Is this really the case? I interpret that the target (100 ms) refers to queueing delay, since LEDBAT tries to minimize target - queueing_delay, where queueing_delay = current_delay - base_delay. Could be wrong though.
Cheers,
Michael
