TTEthernet is a novel communication infrastructures that allows using a single physical communication infrastructure for distributed applications with mixed-criticality requirements, e.g. the command and control systems and audio/video systems. This is achieved via a fault-tolerant self-stabilizing synchronization strategy, which establishes temporal partitioning and, hence, ensures isolation of the critical dataflows from the non-critical dataflows.The focus in this paper is on the dataflow in TTEthernet. For this we take the synchronization as a given and discuss from a TTEthernet user perspective which communication options TTEthernet provides and how they are aligned and realized. While this paper uses TTEthernet as reference communication infrastructure, the methods and strategies presented are valid for any message-based network.
