摘要： Embodiments of this application disclose a packet processing method and a related device. When determining a first network resource based on dynamic information, a network device performs in-band flow measurement in a network domain in which the first network resource is used, to detect actual transmission quality of a packet of an application in the network domain. By comprehensively considering dynamic information, of the application, used when the packet of the application is forwarded by using the first network resource and a detection result of in-band flow measurement in the network domain, the network device obtains a second network resource for forwarding a packet of the application, and forwards a subsequent packet of the application for the application in the network domain by using the second network resource. In this way, a more proper second network resource can be determined based on the dynamic information of the application and the detection result of in-band flow measurement in the network domain, to implement an objective of adaptively and properly planning a network resource used in the network domain, and ensure that the application brings good QoE to a user.

摘要： Embodiments of this application disclose a data packet forwarding method and system, a network node, and a storage medium, and belong to the field of communication technologies. In embodiments of this application, the network node may receive a first data packet, where the first data packet carries first traffic feature data of a first data flow to which the first data packet belongs. The network node may determine a data forwarding policy based on the first traffic feature data. Because the data forwarding policy includes a policy used when the network node forwards a data packet included in the first data flow, the network node may forward the data packet based on the data forwarding policy. It may be learned that, in this solution, there is no need for a controller to determine the forwarding policy and the network node to execute the forwarding policy. Instead, the network node may learn of the traffic feature data of the transmitted data flow in real time, and determine and use the data forwarding policy in a timely manner. In other words, in this solution, real-time performance of determining the data forwarding policy is high, and an emergency in a network can be better coped with in a timely manner.

摘要： This application provides a terminal identification method and an apparatus, and relates to the communications field. The terminal identification method includes: A communications device generates and sends a data packet; and after receiving the data packet, a network device determines, based on terminal information included in an IP packet header of the data packet, a terminal type of a terminal corresponding to the terminal information. Compared with the conventional technology in which terminal information is covered in a process of transmitting a data packet by a network device, and the network device cannot obtain the terminal information, in the technical solution provided in embodiments of this application, the IP packet header of the data packet includes the terminal information. This prevents the terminal information from being overwritten by other information from a network device that forwards the data packet, so that the network device that receives the data packet can obtain the terminal information, and obtain the terminal type of the terminal based on the terminal information.

摘要： A packet sending method, apparatus, and system are disclosed, and belong to the communications field. The method includes: A first device receives a first packet including a network identifier of a virtual local area network and an original packet, where the virtual local area network includes a first host and a second host. The first device obtains a first identifier based on an identifier of the second host and the network identifier, where the first identifier is used to identify a second device, an SRv6 tunnel exists between the first device and the second device, the first identifier includes an indication identifier used to indicate the second device to convert a format of a packet forwarded through the SRv6 tunnel into a format of a packet forwarded through a first NVO3 tunnel. The first device sends an SRv6 packet including the first identifier and the original packet to the second device through the SRv6 tunnel. The method can ensure normal communication between hosts located in a same virtual local area network but in different physical local area networks.

摘要： This application provides a packet processing method, a device, a system, and a storage medium, and belongs to the field of communication technologies. This application provides a method for implementing micro-segmentation in an IPv6 network. An IPv6 extension header of an IPv6 packet carries EPG information, so that the EPG information is visible to a receive end of the IPv6 packet, and the receive end of the IPv6 packet executes a group based policy based on the EPG information in the IPv6 extension header, thereby implementing a micro-segmentation function. Since the IPv6 extension header is more extensible, the problem that a VXLAN header carrying the EPG information is less extensible is resolved, and new functions can be obtained through further extension. In addition, because a packet encapsulation format is simpler, and a header occupies fewer bytes, overheads caused by packet transmission are reduced.

摘要： This application discloses a method and an apparatus for providing a service for a traffic flow. The method includes: A network device receives a first packet; and if a packet feature of the first packet matches a packet feature of the traffic flow, the network device encapsulates an indication identifier of the traffic flow into the first packet to obtain a second packet, and sends the second packet. The second packet is an IPv6 packet or an MPLS packet. The indication identifier of the traffic flow is used to indicate the service provided for the traffic flow. The indication identifier of the traffic flow is encapsulated into the first packet to obtain the second packet. Even if cross-domain transmission needs to be implemented for the second packet, format conversion does not need to be performed on the encapsulated indication identifier, and redundant encapsulation of indication identifiers in a plurality of formats does not need to be performed. The network device in each domain may identify the indication identifier and perform an operation of a corresponding service, to provide the corresponding service.
