Patent ID: 10205607

Abstract:
A method for transmitting messages in a computer network, e.g., a TTEthernet network, the network including nodes and at least one star coupler, which are connected in a multi-hop fashion, the nodes periodically exchanging time-triggered (TT) messages according to a pre-defined transmission schedule, and wherein nodes exchange, according to the schedule, messages via scheduled time-triggered flows, wherein adding a new time-triggered flow into the running computer network includes: 1. determining, for each hop in the new flow path of the new time-triggered flow, a free transmission gap in the transmission cycle of the corresponding port, 2. modifying, if a sufficiently long transmission gap is not free in a transmission cycle, said transmission cycle, wherein 3. modifying transmission cycles occurs iteratively, and 4. if a sufficient transmission gap is found in each transmission cycle along the flow path, the new transmission is incorporated into each of the cycles and executed periodically.
