Generalized Reliability Assessment and Redundant Routing for Safety-Critical Traffic in Time-Sensitive Networking

In safety-critical domains such as avionics and industrial automation, the transmission of network traffic may be affected by transient failures that result in data errors. Time-Sensitive Networking (TSN) enhances traffic reliability through mechanisms like Frame Replication and Elimination for Reliability (FRER), which enables traffic to be multipath through the network by providing link redundancy. However, FRER does not provide a method for assessing reliability and redundant routing. In exis
