<div dir="ltr">server1 has 100 online users server2 has 100 online users the servers are disconnected. Now the servers connect. The online users won't send probes so they won't know about users on the other server until they sign out and login again. It might be acceptable but it's not completely in sync unless the server send probe on behalf of already online users. <div class="gmail_quote">On Sun, Oct 31, 2010 at 3:00 AM, Matthew Wild <<a href="mailto:mwild1@gmail.com">mwild1@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div class="im">On 30 October 2010 19:23, pablo platt <<a href="mailto:pablo.platt@gmail.com">pablo.platt@gmail.com</a>> wrote: > There is still an uncovered point > where both servers have online users and they connect. > </div>XMPP isn't IRC :) Don't think in terms of servers, think it terms of users and subscriptions. If there is a subscription then the user's server will do everything necessary to notify the contacts' servers of their presence, and vice versa. If the contact's server is offline, that presence isn't of any use anyway - the contact is offline. When the server is online again, and the contact signs in, the contact's server sends probes out to discover the status of our user. This way everything stays in sync.
