Abstract
Methods and apparatus are provided for performing efficient transaction processing. A working system processes transactions associated with nodes in a data network. The working system can store information such as, for example call state, accounting, subscriber, and/or session information. The working system identifies characteristics and/or relationship information corresponding to the various transactions to modify transaction information into condensed transaction information. The condensed transaction information can be provided to the redundant system coupled to the working system. Upon failover, the redundant system can use the condensed transaction information to maintain flows, such as, for example voice calls between network nodes.
