Thanks for your reply,
I agree with you.
Duration and quality of links are more qualified.
The TTL value is more qualified to grant transaction.
I needed to know if some other solution could be envisaged.
Your answer confirms my view.
Thanks a lot

Objet : Re: [389-users] Table of duration and acceptable distance between two
(removing 389-devel list from reply, this is probably better on the 389-users list :) )
We don't have tables per-say. We don't have these because there are many factors
involved that you need to consider when designing this kind of topology.
For example, what rate of changes do you expect to be incoming? How much latency and
bandwidth exists between the replicas? How many replicas do you want to deploy? How much
latency are you willing to tolerate between the nodes becoming consistent?
We are aware of a number of deployments that have high rates of change (thousands of
writes per second) that are replicating between continents (ie US/EU). However they also
have high bandwidth/low latency links between these locations to assist this.
So I think there are more questions to answer here about your potential deployment and
your specific concerns you have.
