Design of a QoS-aware framework for industrial CAMX systems

This work introduces a quality of service (QoS) framework for CAMX systems in electronics production. The proposed QoS scheme incorporates elements from the design of the DiffServ architecture, but focuses on server-side processing. An ad-hoc simulator has been produced to validate the expected benefits of QoS discrimination. The results suggest improved performance by over 2 orders of magnitude for signal-carrying data that has direct relationship to process cycles, even during periods of high traffic load and congestion. The performance for non-critical data is not significantly affected and degrades gracefully under increased loads.
