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: A packet transmission method and apparatus, and a system. The method includes: after receiving a first packet, a first device determines, based on a condition met by a first number carried in the first packet, a manner of sending the first packet. When the first number of the first packet meets a first condition, a second device determines a second cycle label corresponding to a first cycle label and sends the first packet to a third device in a cycle corresponding to the second cycle label. When the first number of the first packet meets a second condition, the second device determines a third cycle label corresponding to the first cycle label and sends the first packet to the third device in a cycle corresponding to the third cycle label.

Abstract: Embodiments of this application provide network traffic marking and measurement methods and a node, and relate to the field of communications technologies, and specifically, to network traffic measurement and network traffic distribution. The network traffic measurement method includes: receiving, by a second node, a data packet sent by another node in a network, where the data packet is periodically marked by the another node, and each node has a different period of marking a data packet. According to the application, the second node may distinguish, based on the period of marking the data packet, traffic sent by the another node in the network, to obtain network traffic sent by the another node in the network to the second node. Upon implementing the traffic measurement method, data plane overheads can be reduced, and a hardware implementation process is simplified.
