Abstract:
Distributing the right information at the right
time is an apparent need of the fast moving globe. Publishsubscribe
communication paradigm plays a major role in the
systems built to accomplish this need. It has been adopted in
variety of today’s business domains such as mobile
communication, database integration, road traffic visualization
etc. With large-scaled, distributed and heterogeneous nature of
these systems, there is a high demand for an efficient, scalable
and interoperable messaging middleware which is capable of
handling the increasing load of messages. As discussed in
earlier works, network of messaging brokers that
collaboratively act as a single entity provides a scalable
architecture for such publish-subscribe middleware. This
paper describes two algorithms named tree and cluster that we
designed which are used as two approaches for topology of the
broker network and evaluates the performance of the
distributed publish-subscribe middleware with respect to those
two topologies.
