Multiple micro broker components can also connect and send messages between each other.
For example, a retail store application uses multiple micro broker components. Each micro broker handles messages from a set of RFID readers. A tag is read by the reader that it passes through as well as additional readers; hence, the tag is passed to multiple micro broker components. By linking micro broker components together, RFID tag messages are correlated across brokers.
