You can connect several service integration buses in a
network directly, or indirectly, by creating and configuring foreign
bus connections. You can connect a service integration bus and a WebSphere
MQ queue manager or queue-sharing group in a similar way. You can
enable point-to-point or publish/subscribe messaging across multiple
buses.
About this task
For a conceptual overview of connecting different service
integration buses, including security issues, see
Interconnected buses.
You can configure a bus to connect to, and exchange
messages with, other messaging networks. To do this, you must configure
a foreign bus connection. A foreign bus connection encapsulates information
related to the remote messaging network, such as the type of the foreign
bus and whether messaging applications are allowed to send messages
to the foreign bus. Messages route
to a foreign bus either directly through a link between the local
bus and the foreign bus, or indirectly through one or more intermediate
buses.
