Hazelcast supports different implementations for WAN replication through its WanPublisher and WanConsumer interfaces.

By default Hazelcast uses WanBatchReplication implementation which creates TCP connections to target members and send the WAN events in batches. This implementation also has in-memory (replicated) queues to send events asynchronously and to deal with differences of WAN link throughput.

You can replace this implementation with SolaceWanPublisher which publishes WAN events to Solace queues and doesn't use the direct TCP link approach used by WanBatchReplication. Replication of WAN events are provided by Solace and target members consumes events from that queues. So source and target members are unaware of each others network topology.

You may want to check Hazelcast Documentation or this white paper for details.
