Bus destinations

A bus destination is a virtual location within a service integration bus, to which applications attach as producers, consumers, or both to exchange messages.

This topic provides a brief description of general destination concepts. For more detailed descriptions of specific types of destinations, see Learning about bus destinations.

Bus destinations can be either "permanent" or "temporary":
The following are the main types of destination:
Queue
A destination for point-to-point messaging.
Topic space
A destination for publish/subscribe messaging.
Alias
An alias destination makes a destination available by another name and, optionally, overrides the parameters of the destination. Applications can use an alias destination to route messages to another destination in the same bus or in another (foreign) bus.
Foreign
A foreign destination provides a mapping to a destination of the same name on a different bus and enables applications on one bus to access directly the destination on another bus. You can set its own destination properties which will override the destination defaults.

You can configure queue, topic space, and alias destinations with one or more mediations that refine how messages are handled by the destination.

You can configure queue, topic space, and alias destinations with routing paths.

Applications use API-specific artifacts like a JMS queue, which is associated with a queue destination.

The mediations, default forward routing path, and reply destination are all mechanisms that the administrator can use to modify the flow of messages through the service integration bus. The administrator can create and modify these mechanisms without the sending and receiving applications having to be aware or without any need for the applications to be modified.
