摘要： This application relates to the field of communications technologies, and provides a multicast packet sending method and an apparatus. In the method, a first node obtains a first multicast packet including multicast routing information of a second node, and sends the first multicast packet to the second node. The second node is a non-leaf subnode of the first node in a multicast tree. Multicast routing information of a node includes a multicast routing identifier of the node and multicast routing information of a non-leaf subnode of the node in the multicast tree. A multicast routing identifier of a node is used by the node to determine a subnode of the node in the multicast tree. The multicast routing information is embedded in the multicast packet, and multicast routing information of a tree recursive structure included in the multicast packet can describe packet forwarding information of the multicast tree or a subtree of the multicast tree. Therefore, scalability is good, and a forwarding path can be conveniently planned and specified based on a requirement.

摘要： Embodiments of this application provide a method for sending a data packet. The method includes: A second network device may determine a remaining processing time of a data packet on a first network device based on a predefined first delay. When the remaining processing time is greater than 0, a moment at which the data packet enters a queue on the second network device serves as a start moment, and after a period of time, the remaining processing time ends at a second reference moment corresponding to the data packet. The remaining processing time is consumed on the second network device.

摘要： 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. After the received first packet reaches the time difference and is queued in a queuing system of the second network device, the third packet is sent to a next-hop network device of the second network device. By actively delaying a to-be-transmitted packet, a deterministic delay of the to-be-transmitted packet in a transmission process is ensured. This method is applicable to IP networks of various scales.

摘要： This application provides a resource reservation method and an apparatus. The method includes: receiving, by a node, a first message, where the first message carries a bandwidth value r1 of a resource requested to be reserved and a quantity Q1 of cycles occupied by the resource, the node maintains resource reservation states in K cycles, K is a positive integer, and Q1 is less than or equal to K; and updating, by the node, resource reservation states in Q1 of the K cycles based on the bandwidth value r1 and the quantity Q1. The node maintains the resource reservation states at a granularity of cycles. Therefore, the resource reservation states that need to be maintained by the node do not depend on a quantity of data flows processed by the node, and a performance requirement of a resource reservation for the node can be lowered.

摘要： An access control method and a related apparatus are provided. The method includes: A computer device sends a source identifier and a target identifier to a first network device; and the first network device determines, based on the source identifier, the target identifier, and an access control list, an association attribute and a first target constraint item corresponding to the association attribute, determines a first verification code based on the association attribute and the first target constraint item corresponding to the association attribute, and then sends, to the computer device, first indication information that includes at least the first verification code. Then, the computer device determines the association attribute and first target information corresponding to the association attribute, adds, to a packet for accessing a target resource, the association attribute and the first target information corresponding to the association attribute, and sends the packet, where the packet further includes at least the first indication information. In addition, a third network device verifies the packet based on the association attribute and the first target information corresponding to the association attribute in the received packet, and sends or discards the packet based on a verification result. Verifying the packet based on the association attribute and related information of the association attribute reduces operation and maintenance costs of an ACL, and improves network security.

摘要： Embodiments of this application disclose an identity authentication system, method, apparatus, and device, and a computer-readable storage medium, and belong to the field of security technologies. In an embodiment of this application, a symmetric key based identity verification method is implemented by sharing the first symmetric key between the terminal device and the authorization device. In this way, when confidentiality of the symmetric key is ensured, authentication code generated based on the symmetric key in an entire identity authentication process is not easily forged, so that security and reliability of identity authentication can be ensured. In addition, in this solution, bidirectional identity authentication of the terminal device and a registration device is implemented by using the authorization device, to avoid a security issue of unidirectional identity authentication. That is, security of this solution is higher.

摘要： Embodiments of the present invention provide a packet processing method, including: receiving, by a first node, a first packet, where the first packet carries a first bit string, the first bit string includes M bit sets, each bit set corresponds to one node group, a value of the bit set is used to indicate whether one or more target nodes of the first packet include the corresponding node group, and M is an integer greater than or equal to 1; and determining, by the first node based on the first bit string and a second bit string, whether to send the first packet to a second node, where the second bit string includes N bit sets, each bit set corresponds to one node group, a value of the bit set is used to indicate whether a node belonging to the corresponding node group exists in one or more related nodes of the first node, and N is an integer greater than or equal to 1. The node needs to store only the second bit string, without storing a complex forwarding entry, and determines, based on the first bit string and the second bit string, whether to forward the packet. This does not require a high computing capability of the node.
