Abstract: Disclosed are a communication system. All nodes in the communication system belong to a same layer 2 network. Well-known information of the layer 2 network can be obtained by the node. The node obtains the well-known information and forms a well-known key based on the well-known information and a preset key derivation algorithm; obtains a local MAC address of a first node and forms a first random number; forms first plaintext data based on the local MAC address and the first random number; and encrypts the first plaintext data based on the well-known key and a symmetric encryption algorithm, to form a first network layer address. Each node forms the well-known key based on the well-known information and the key derivation algorithm, and forms the network layer address based on the well-known key, the local MAC address, and the symmetric encryption algorithm.

Abstract: This application provides wireless communications configuration methods and apparatuses. One method includes: receiving, by a service node of a server, a first packet sent by a client device, wherein a destination address of the first packet is an internet protocol (IP) address of the server; sending, by the service node, a second packet to the client device, wherein the second packet comprises the IP address of the service node; and receiving, by the service node, a third packet sent by the client device, wherein a destination address of the third packet is the IP address of the service node that is different from the destination address of the first packet.

Abstract: This application provides a secure route identification method and an apparatus. A first AS node receives a first message. The first message is used to indicate a target path for reaching a first route prefix, and the target path is used to indicate a first neighboring relationship between AS nodes on the target path. Then, the first AS node determines, based on the first neighboring relationship and neighbor information of an AS node on the target path that is stored in a blockchain, whether a security threat exists on the target path. The neighbor information of the AS node on the target path includes a second neighboring relationship between the AS node on the target path and another AS node.

Abstract: This application discloses a packet transmission method, an apparatus, a device, and a readable storage medium, and relates to the field of communication technologies. The method applied to a second network device includes: First, a first packet sent by a first network device is received, and then a second packet, a first dwell time period, and a second dwell time period are obtained based on the first packet. Then, a time difference between the second dwell time period and the first dwell time period is determined. Then, a third dwell time period and a fourth dwell time period are determined, to encapsulate the third dwell time period, the fourth dwell time period, and the second packet to obtain a third packet.
