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.

Abstract: 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.
