WebSphere MQ Multicast Transport

Start of changeWebSphere® MQ Multicast Transport is a service that connects dedicated JMS application clients and is optimized for high volume, one-to-many publish/subscribe topologies.End of change

Start of changeWebSphere Event Broker provides support to allow these clients to communicate with other applications through message flows in a broker.End of change

Applications that connect using WebSphere MQ Multicast Transport and the JMS API use predominantly the publish/subscribe model. The applications must be multicast-enabled to use this protocol.

Start of changeThe ability to communicate with a broker means that JMS application multicast clients can communicate with applications that use other supported protocols and transports.End of change

Start of changeTo use the WebSphere MQ Multicast Transport, you must deploy a message flow that contains a Real-timeOptimizedFlow node or a Real-timeInput node to your broker. The message flow can send output messages to other real-time applications, using either the Real-timeOptimizedFlow or the Publication node.End of change

This protocol is a non-queued transport: applications communicate with the broker by writing data directly to TCP/IP ports and the input nodes are configured with a TCP/IP port number on which the broker listens for incoming connections. Client applications that use the WebSphere MQ Multicast Transport connect to this port.

The following built-in nodes are provided to support this protocol:
