Craciunas Wilfried Steiner TTTech Computertechnik AG, Vienna, Austria {rse,scr,wst}@tttech.com Abstract—Time Sensitive Networks (TSN) emerge as the set of sub-standards incorporating real-time support as an extension of standard Ethernet. WebWe consider that the tasks are scheduled using static cyclic scheduling and that the messages use the time-sensitive traffic class in TSN, which relies on schedule tables (called Gate Control Lists, GCLs) in the network switches. A configuration consists of the schedule tables for tasks as well as the disjoint routes and GCLs for messages.
