Hi Vincent,
skipping the fact that the pa module from OpenSER is still not mature and the presence encoding is not compatible between all SIP UA, in order to distribute the presence related traffic you may use several presence openser server; Based on static rules, the proxy may distribute the traffic among the presence servers - static load-balancing. Like the present of users from A to E will be kept on server1, for users from F to J will be kept on server2 and so on.....
just an idea....

Hi,
I need some advices about a design issue. I'm trying to figure out how to manage my presence information notifications, using RFC 3856.
I have a situation in which end-to-end presence management wouldn't be suitable.
Still I'm wondering if server based presence management is a good idea. My thought is that it present a scalability issue. The point is that having the presence server would have to handle every single SUBSCRIBE & PUBLISH request then sends NOTIFY to every watchers.
Is it an efficient way to handle presence in a network with hundreds online users, everyone having tens of contact on their list.
Thank you for your comments
