Abstract:
This paper develops a performance model for a class of soft real time
systems. The incentive came from a specific commercial system; however the
resulting model can have other applications. The model incorporates a set of
properties that are not all common in prior models such as a queueing network
with a polled serving pattern, programmable priority levels, multiple message
classes, network-load-dependent multiple service, and a subset of queues with
direct feedback. The analytical model can estimate performance parameters for
both the overall queuing network and its specific queues. The model can be used
to aid design decisions at an early stage, and can be used for later system
calibration and diagnosis. Both the performance model and a sample application
are described.
