store-and-forward (adj)~ A method of delivering transmissions in which messages are held temporarily by an intermediary before being sent on to their destination. Store and forward is used by some switches in delivering packets to their destinations. store-and-forward replication (n)~ A replication model used by Active Directory in which changes are not sent directly from one domain controller to all other domain controllers.

Replication through neighboring systems is also called transitive replication.
