Der Client erhält die gleichen Informationen von mehr als einem Server, indem er die Daten auf mehr als einem Server sammelt und veröffentlicht. Dieser Modus stellt sicher, dass es keine Unterbrechung des Datenstroms und keinen Datenverlust gibt. Der Client sollte gewährleisten, dass er doppelte Daten erkennt und zwei Datenströme verarbeiten muss.
