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.
