Packet transportation methods and configuration

The method you choose for transporting packets between replicas depends on connectivity. If your replicas do not have IP connectivity, you must use a file-based transport method. If your replicas have connectivity, you can use the store-and-forward facility.

Choosing a packet transport method lists the recommended methods for various situations.
