A method of distributing messages from a server system to a plurality of client systems comprises defining, for each client system, a quality of service (QoS) level for messages provided by the messaging system to the client system; defining, as between the messaging system and each client system, a message processing capacity provided by a client to the messaging system; and degrading the QoS level of messages in the event that the client system does not provide the defined message processing capacity to the messaging system. |
