Abstract: A time-triggered Ethernet (TTE)-based data transmission method and node device, solving the problem of wasting network bandwidth resources in the prior art during TTE-based data transmission; in the method, a main node determines a scheduling period table based on a time-triggered packet; when a node has a to-be-transmitted event-triggered packet, and the node determines, according to the information stored in the scheduling period table, that a physical link occupied by the event-triggered packet is not in conflict with a physical link corresponding to the current time slot, the node transmits the event-triggered packet in the current time slot. The main node does not need to separately allocate time for the event-triggered packet of each node. Therefore, when a node has a to-be-transmitted event-triggered packet, the node can transmit the event-triggered packet in the current time slot as long as the physical link occupied by the event-triggered packet is not in conflict with the physical link corresponding to the current time slot, thus effectively improving data transmission efficiency and network bandwidth utilization.
