Selected sections of this report were presented at the Ersads 2001, European Research Seminar on Advances in Distributed Systems, 14-18 May 2001, Bertinoro (Forlì), Italy.
This paper outlines an architecture that intends to ensure Quality of Service (QoS) to applications using the publisher-subscriber paradigm. The key idea is to subscribe information not only by subject and content but also according to QoS parameters. This must be done with cooperation of all intervenients: publishers, which should tag information they are producing with application-level QoS parameters; subscribers, that do content-based QoS addressing; and message brokers, which use a QoS based network infrastructure.
