Description
Summary:Industrial automation networks are composed of cyber-physical systems where frame delays and jitter influence significantly the quality of communication between control and field devices. Due to these constraints, such systems are often served by dedicated Fieldbus networks which are different from networks for enterprise-level connectivity. However, with the introduction of Time-sensitive Networking standards which are already integrated into IEEE 802.1Q-2018 standards in essential parts, the long expected single converged network for any-type communication in the field, control, and enterprise level is within reach. With it, comes the challenge of synthesizing schedules to obtain parameters for configuring the network bridges for time-triggered communication services.This paper provides a scheduling verification, and Gate Control event computation algorithm focused on asserting the viability of scheduling communication services for multiple independent periodic Talker applications on IEEE 802.1Q- Time Sensitive Networks as well as the computation of Gate Control Lists for the bridges.
