Embodiment
[0023] The following will refer to Figure 1-6 Embodiments of the present invention will be described.
[0024] Such as figure 1 As shown, this embodiment proposes a real-time Ethernet scheduling method for transmitting real-time data, including the following steps:
[0025] Step 10, generate an offline scheduling table according to the network topology and the real-time message to be transmitted;
[0026] Further, before step 10, a real-time message to be transmitted is generated according to the received real-time message and data to be inserted, wherein the data to be inserted includes an identification bit, a message sequence number and a data payload length.
[0027] Specifically, such as figure 2 As shown, three new data are added in the real-time message: the is-copy flag in the unique data identifier flow-id, the sequence number of the message, and the length of the data payload. Among them, flow-id and length each account for 16 The sequence occupies 32 bits, and...
