WAN message routing

Non-gateway replication servers forward update messages from replicas to co-located replication servers only. It is the responsibility of the WAN gateway server to forward these messages to WAN gateway servers at other locations.

The following figure illustrates how an update message is routed from a non-gateway server to a remote location.

A workflow diagram showing the WAN gateway message routing between 3 servers/data stores: Identity Data Store 1/ReplicationServer 1/NORTH location, Identity Data Store 2/Replication Server 2/NORTH location, and Identity Data Store 3/Replication Server 3/SOUTH location. The internal routing and replication workflow between the 3 Data Stores are described in 4 steps.

Processing steps

  1. Update received at Identity Datastore 1 at the north location is sent to the embedded Replication Server.

  2. Replication Server 1 routes message to the WAN Gateway only.

  3. The WAN Gateway at the North location (Identity Data Store 2) routes message to Replica 2 and to the WAN Gateway at the south location.

  4. Replication Server 3, which is the WAN Gateway at the south location, routes the message to Replica 3.
