    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.

    Abstract: Provided are a transparent clock passive port election method and device based on the PTP protocol. In the method, by extracting the TLV field of a received announce message, a first port of a network device acquires the clock identification information, forwarding times information and port identification information carried in the TLV field, and then compares the forwarding times information and clock identification information carried in the TLV field to the forwarding times information carried in the TLV field contained in a received announce message from a port by itself, and its own clock identification information, so as to select a port as a passive port. Therefore, by adding the comparison factors, such as clock identification information, forwarding times information and port identification information, in the TLV field of an announce message, a transparent clock is allowed to support the PTP protocol, thus avoiding a protocol storm formed by a PTP message in a complex topology network and a ring network constituted by the transparent clock to improve the stability of the network.
