You can implement the "publish/subscribe" messaging approach in MQSeries with the Pub-Sub SupportPac or with Integrator. To alleviate the complexity of a multiple queue manager topology, MQSeries introduced the concept of Message Brokers with the MQSeries Integrator product. The following graphic illustrates five queue managers configured to use a Message Broker:
In addition to the Message Broker, the Integrator product also supports a Message Repository Manager, and the publish and subscribe messaging approach.

Publishers only know of the topics they describe for their messages, and subscribers only know of the topics they requested.
