Abstract
A system and method of replicating changed data between an active process and a standby process is provided. The active and standby processes each include an application and a processor having memory. The method includes organizing active and standby processor memories into regions, with each region including one or more tuples, datamarking the tuples having changed data in the active processor corresponding to the active application, and transferring copies of the changed data from the active process to the standby process to replicate data between the active and standby processors. The system includes means for datamarking changed data and transferring copies of the changed data between active and standby processes having active and standby processors configured as mated pairs. The system can include a wireless cellular communication network having an active process including an active radio control software application running on an active processor and a standby process including a standby radio control software application running on a standby processor.
