Active Directory Replication Model Technical Reference
The Active Directory directory service replication model ensures that Active Directory data on one domain controller is consistent with the replica of the same data on other domain controllers in the same domain. The Active Directory replication model determines how changes to Active Directory data are propagated and tracked automatically between domain controllers. The replication model allows directory data on each domain controller to be updated directly. Each domain controller maintains replication metadata that indicates the update status both for itself and relative to other domain controllers. In addition, the replication model allows each domain controller to request (pull) only changes that need to be replicated and to forward changes to other domain controllers that need them.
