Abstract

A system and method for buffering messages between at least two applications over a network implementing a Quality of Service (QoS) framework. Messages are transmitted from a source application to an intermediary message queue for message buffering. A message queue QoS is imparted at the message queue to the flow of the messages traversing the message queue, and the end-to-end QoS can then be provided for the flow of messages over the network.
