Abstract: The present invention provides a packet processing method and system, and a network device. The method includes: receiving, by a first network device, a packet, where the packet includes match object information and match condition information; determining, by the first network device, a to-be-matched second network device according to the match object information, where the second network device includes one or more network devices; matching, by the first network device, device information of the second network device with the match condition information; and performing, by the first network device, forwarding processing or discarding processing on the packet according to a match result of matching the device information of the second network device with the match condition information. By using the method provided in the present invention, excessive occupation of network bandwidth can be reduced, and network resources can be saved.

Abstract: 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.

Abstract: A routing table creation method, an electronic device, and a network are provided. The method includes: generating a first probe packet, where the first probe packet has a source address and a destination address; sending, from a source node corresponding to the source address, the first probe packet on a network including at least two nodes, until the first probe packet reaches a destination node corresponding to the destination address, and recording addresses of nodes through which the first probe packet passes, to form a first path; generating a second path according to the first path, where the second path is a reverse path of the first path; generating a first response packet, sending the first response packet along a second path until the first response packet reaches the source node; and creating a routing table entry according to the second path.
