Subscribers

A subscriber is an application that requests information about a specified topic from a publish/subscribe broker.

The application might be a WebSphere MQ, WebSphere Business Integration Message Broker, WebSphere MQ Everyplace, SCADA, or JMS/IP application.

The subscriber sends a subscription request to a broker to specify which publications it wants to receive. The request defines the topic, the filter, and the subscription point of each publication, and also specifies the name of a queue to which the publications should be sent. This queue is known as the subscriber queue.

Messages that are published by a publisher can be received by more than one subscriber, and a subscriber can receive messages, on the same or different topics, from more than one publisher.
