Message broker using tree structures

摘要

A message broker 12 provides for application integration amongst a plurality of data processing applications. The broker has a plurality of data processing nodes, where the data processing applications communicate by passing messages through data processing nodes of the broker. Messages received by the broker are transformed into a tree structure before being passed through data processing nodes of the broker. A list of destinations for a message is generated while a message passes through a data processing node of the broker. The list of destinations is also represented as a tree structure so that the list of destinations can be processed by the data processing nodes of the message broker.
