Abstract :
To guarantee a deterministic transfer delay for cyclic control data in switched industrial Ethernet, the IEEE 802.1p queuing feature is introduced into Ethernet switches and source nodes, which gives real-time data the priority to access network resources. And simultaneously a leaky bucket regulator is also introduced into source nodes to constrain the traffic entering into the network, which prevent acyclic data from deteriorating the switch temporal behavior. Then the maximum closed-loop control delay for cyclic control data is determined based on network calculus
