[cisco-voip] Presence Rebalance Users Specific Nodes

[Wes Sisk]

Jaime,

Agreed, Cisco's current approach to load balancing across the UC portfolio pretty much requires manual assignment.  Even in CUCM where load balancers and firewalls can redirect UDP/TCP sessions this causes problems in the backend call processing as the server side includes some assumptions as where sessions should be.

There is great interest in changing this architecture to enable more automation. For now manual is the requirement.

Regards,
Wes

Hi Wes,

Yeah this is the only way I know to balance the users just in the desired nodes, but it has to be performed by hand while with rebalance, users are being assigned automatically.

Thank you anyway!
