Scalable QoS-Based Event Routing in Publish-Subscribe Systems

This paper proposes a distributed and scalable publish-subscribe broker with support for QoS. The broker, called “IndiQoS”, leverages on existing mechanisms to reserve resources in the underlying network and on an overlay network of peer-to-peer rendezvous nodes, to automatically select QoS-capable paths. By avoiding flooding of either QoS reservations or link-state information, IndiQoS is able to scale with respect to network size and number of reservations. Experimental results show the validity of our approach.
