ABSTRACT:
A method comprises estimating a performance of a processing system using queuing theory wherein the processing system comprises a network that accepts at least one input message stream from a plurality of publishing clients, transforms the at least one input message stream into at least one output message stream utilizing the plurality of transforms distributed in a first assignment among the plurality of brokers, and delivers the at least one output message stream to at least one of the plurality of subscribing clients, performing optimization upon the assignment of the plurality of transforms using the estimated performance to produce a second assignment, and reassigning the plurality of transforms in accordance with the second assignment.
