i need to loadbalance udp application from an appliance (Arbor). But this udp application is using same source port for every new sessions. The ACE sees this as a similar session and no loadbalacing is perform?

udp-fast-age is called 'per packet load balancing' in the manual. Actually, it is per-packet provided there is a response to each UDP packet as the response makes the connection to be flushed.

The UDP idle connection timeout is 120 s by default. I think the continuous stream maintains a single connection permanently even if you decrease that value (set timeout inactivity command) but it may be worth a test.
Per-packet LB can be done by a CEF router. ACE is connection-oriented - as far as I know.

embedded databases synchronized in real time. Therefore, when the active
DCNM is not functioning, the standby DCNM will...
