[ntp:questions] NTP and asymetric delay

[emmanuel.python at bluewin.ch]

Hello

I use the version 3 of NTP on cisco routers and I see that if the 
delay between the NTP server and the client (my cisco router) is not 
symetrical (like for example 20ms in one direction and 40ms in the 
other direction) then the time is not very well synchronized on the 
router => There is an error of 10ms ((40-20)/2). After reading the 
NTP algorithm, I see that it uses the round trip time to compute the 
clock offset. So my question is the following: How to configure or 
use NTP if there are asymetrical delays or jitter?

Thank you for your help
