Autonomic control plane packet transmission method, apparatus, and system
A method includes: setting up, by a first network device, a MACSec channel to a second network device according to the MACSec protocol; and sending, by the first network device, an ACP packet to the second network device by using the MACSec channel, where the ACP packet is carried in a MACSec frame, and a frame header of the MACSec frame carries identification information used to identify the ACP packet. By means of the packet transmission method, a MACSec channel is set up between adjacent nodes in a self-organizing network according to the MACSec protocol, and an ACP packet is transmitted between the adjacent nodes by using the MACSec channel and processed.
1. A packet transmission method applied to a self-organizing network, the method comprising:

sending, by the first network device, a MACSec frame, to the second network device by using the MACSec channel, wherein the MACSec frame comprises an autonomic control plane (ACP) packet,
wherein the MACSec frame comprises a frame header containing identification information and the identification information is configured to indicate that the MACSec frame carries an ACP packet,
wherein the identification information is carried in an Ethernet type field in the frame header of the MACSec frame; or
wherein the identification information is carried in a flag bit field in the frame header of the MACSec frame; or
wherein the identification information is carried in a MAC address field in the frame header of the MACSec frame.
2. The method according to claim 1 , wherein the flag bit field is an additional field or a version field.
3. A first network device for packet transmission applied to a self-organizing network, the first network device comprising:
a memory comprising instructions; and
one or more processors coupled to the memory and configured to execute the instructions to:
set up, according to a Media Access Control Security (MACSec) protocol, a MACSec channel to a second network device; and
send a MACSec frame to the second network device by using the MACSec channel, wherein the MACSec frame comprises an autonomic control plane (ACP) packet,
wherein the MACSec frame comprises a frame header containing identification information and the identification information is configured to indicate that the MACSec frame carries an ACP packet,
wherein the identification information is carried in an Ethernet type field in the frame header of the MACSec frame; or
wherein the identification information is carried in a flag bit field in the frame header of the MACSec frame; or
wherein the identification information is carried in a MAC address field in the frame header of the MACSec frame.
4. The first network device according to claim 3 , wherein the flag bit field is an additional field or a version field.
5. A second network device for packet transmission applied to a self-organizing network, the second network device comprising:
a memory comprising instructions; and
one or more processors coupled to the memory and configured to execute the instructions to:
set up, according to a Media Access Control Security (MACSec) protocol, a MACSec channel to a first network device; and
receive, by using the MACSec channel, a MACSec frame, sent by the first network device, wherein the MACSec frame comprises an autonomic control plane (ACP) packet,
wherein the MACSec frame comprises a frame header containing identification information and the identification information is configured to indicate that the MACSec frame carries an ACP packet,
wherein the identification information is carried in an Ethernet type field in the frame header of the MACSec frame; or
wherein the identification information is carried in a flag bit field in the frame header of the MACSec frame; or
wherein the identification information is carried in a MAC address field in the frame header of the MACSec frame.
