Connect buses
We can connect several service integration buses in a network directly, or indirectly, by creating and configuring foreign bus connections. We can connect a service integration bus and a WebSphere MQ queue manager or queue-sharing group in a similar way. We can enable point-to-point or publish/subscribe messaging across multiple buses.
For a conceptual overview of connecting different service integration buses, including security issues, see Interconnected buses. We can configure a bus to connect to, and exchange messages with, other messaging networks. To do this, 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.

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.
- Manage messages that use foreign bus connections
Manage messages that use a foreign bus connection.
- Modify a routing definition
We can view or change the routing definition of an existing foreign bus connection between a local bus and a foreign bus. The routing definition defines the virtual link between two buses that enables them to exchange messages. The routing definition can define properties for a virtual service integration bus link, a virtual WebSphere MQ link, or an indirect foreign bus connection.
- Configure service integration bus links
We can configure service integration bus links on messaging engines in a variety of ways. For example, we can start, stop, or remove links.
- Configure topic space mappings between service integration buses
A topic space mapping allows subscribers on the local topic space to receive messages published in the foreign topic space. We can configure topic space mappings between a local service integration bus and a foreign service integration bus.
- Topic names and use of wildcard characters in topic expressions
Wildcard characters can be used in topic expressions to retrieve topics provided by the default messaging provider and service integration technologies.
