The webMethods Broker systems allows two or more Brokers to share information about their event type definitions and client groups. This sharing of information enables communication between Broker clients connected to different Brokers. The next figure shows how an event published by a client program connected to Broker_1 can be received by a client program connected to either Broker_1, Broker_2, or Broker_3.

In order to share information and forward events, Brokers must join a territory. All Brokers within the same territory have knowledge of one another's event type definitions and client groups. For more information on this feature, see Administering webMethods Broker.
