Abstract: A method, program and system for synchronizing a network manager to a network agent, wherein, in a communications network in which managers maintain data unit copies of data units of their agents, a unique first value, a second value for indicating the number of changes to the associated data unit and a third value for indicating who initiated the respective last change are stored for each data unit in the agent. A copy of the associated three values is stored for each data copy in the manager, and the copies are compared with the respectively associated three values which are stored in the agent. Each data copy whose copies of the three values which are stored in the manager do not match the associated three values which are stored in the agent A is synchronized to the associated data unit which is stored in the agent.
