Link transmitters [Collection]
A link can have multiple link transmitters. For applications that use point-to-point messaging, there is one link transmitter on each messaging engine in the source bus. For applications that use publish/subscribe messaging, there is one link transmitter for each topic space in the source bus. The link transmitter acts as a transmission queue where produced messages are persisted before transmission across the service integration bus link or IBM MQ link to the foreign bus.
