I have configured freediameter server and client application and exchanged messages using test app. I would like to know how High availability or fault tolerance is supported for sessions in Free diameter. I am planning to write Ro and Rf extensions over fd and would require some HA. Basically I am looking for a method to extract stack session states and store in in my app and during failover use this info to re-build the stack state in standby.
Any help would be highly appreciated
