Abstract: 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.

Abstract: Embodiments of this application provide a method and an apparatus for establishing a blockchain node connection, and a device. The method is applied to a blockchain system, and includes: A first node obtains address information of a second node from a first router. The first router and the first node are located in a first autonomous system. The second node is located in a second autonomous system. The first autonomous system and the second autonomous system are neighboring autonomous systems. The first node establishes a connection to the second node based on the address information of the second node. This improves blockchain communication security.

Abstract: This application provides a packet sending method. The method includes: receiving, by a target service node, a first packet sent by a client, where a destination address of the first packet is an IP address of a server; sending, by the target service node, a second packet to the client, where the second packet includes an IP address of the target service node; and receiving, by the target service node, a third packet sent by the client, where a destination address of the third packet is the IP address of the target service node. The client changes a destination address from the IP address of the server to the IP address of the target service node to send the third packet, and the server directly forwards the third packet to the target service node with no need to record a correspondence between the client and the target service node.

Abstract: This application provides service obtaining and providing methods, user equipment, and a management server. The service obtaining method includes: determining, by user equipment, a first Internet protocol IP address by using a preset algorithm based on a service name of a to-be-accessed service; sending, by the user equipment, a communication data packet by using the first IP address as a destination address; and receiving, by the user equipment, the service provided by a serving-end device.

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 link-state advertisement LSA sending method, an apparatus, and a system, to reduce a quantity of LSA sending times. The method includes: generating, by a first router, a first path table based on level location information of the first router, level location information of a second router, and level location information of at least one third router; sending, by the first router, a first link state update LSU message to the second router; receiving, by the second router, the first link state update LSU message from the first router; updating, by the second router, a link state database LSDB of the second router based on a first LSA; and sending, by the second router, the first LSA to a router corresponding to an identifier in the first path table.
