A packet transmission method is applied to a communication device including a first MPU, a second MPU, and an LPU. The first MPU is connected to the LPU through a first transmission channel. The second MPU is connected to the LPU through a second transmission channel. During packet transmission, a service flow packet is transmitted through the first transmission channel, and a non-service flow packet is transmitted through the second transmission channel. Therefore, the service flow packet and the non-service flow packet are processed by different MPUs, so that the service flow packet and the non-service flow packet do not compete with each other. In this way, transmission efficiency of the non-service flow packet is improved. In addition, when the first MPU is attacked by an abnormal service flow packet, the second MPU is not affected, and may normally perform operation and maintenance management.

Techniques are disclosed for the identification of applications from communication sessions of network traffic between client devices and the generation of application-specific metrics for network traffic associated with the applications. In one example, a router obtains metrics for a plurality of packets. The router determines a session of a plurality of sessions associated with each packet. For each determined session, the router generates metrics for the session from the metrics of the packets associated with the session and determines an application of a plurality of applications associated with the session. For each determined application, the router generates metrics for the application from the metrics of the sessions associated with the application and transmits, to a device, the metrics for the application. In some examples, the router generates the metrics for each application on a per-client, per-next-hop, or per-traffic class basis.

This application discloses a packet transmission method, an apparatus, a device, and a computer-readable storage medium, and belongs to the field of communication technologies. For example, the method is applied to a first device. The method includes: The first device receives a first packet, where the first packet includes quality guarantee indication information and information about a first application, and the first packet belongs to the first application for which quality guarantee needs to be provided. The first device stores a correspondence between the information about the first application and the quality guarantee indication information based on the received first packet. After receiving a second packet including the information about the first application, the first device provides quality guarantee for the second packet based on the stored correspondence.

In one embodiment, a method includes determining, by a first router, service level agreement (SLA) requirements for an application and generating, by the first router, first SLA characteristics for the first router. The first router is in an active mode within a network. The method also includes comparing, by the first router, the first SLA characteristics for the first router to the SLA requirements and determining, by the first router, second SLA characteristics for a second router. The second router is in a standby mode within the network. The method further includes comparing, by the first router, the second SLA characteristics for the second router to the SLA requirements and determining, by the first router, whether to lower a first hop redundancy protocol (FHRP) priority of the first router.

A service execution method and apparatus, a system, and a storage medium related to the communications field are provided. The method includes: a first network device generates a first packet, where the first packet includes a segment routing header (SRH), the SRH includes a service identifier, and the service identifier is related to first service information and second service information. The first network device sends the first packet to a second network device, wherein the service identifier indicates the second network device to execute at least one service based on the first service information, the second service information, and the first packet. According to this application, a problem that a network service cannot be provided for an actual service packet in an SRv6 network can be resolved.

A method for managing network connections includes steps of: in response to receipt of a request for establishing a new network connection, storing in a connection-tracking (Conntrack) table an entry of tracked connection data that is related to the new network connection to be established, and updating a current tracked-connection count by adding one thereto; determining a priority level of the new network connection according to a data packet transmitted through the new network connection; and determining whether to output data packets that are received through the new network connection based at least on the current tracked-connection count and the priority level of the new network connection.

In general, the disclosure describes techniques for measuring edge-based quality of experience (QoE) metrics. For instance, a network device may construct a topological representation of a network, including indications of nodes and links connecting the nodes within the network. For each of the links, the network device may select a node device of the two node devices connected by the respective link to measure one or more QoE metrics for the respective link, with the non-selected node device not measuring the QoE metrics. In response to selecting the selected node device, the network device may receive a set of one or more QoE metrics for the respective link for data flows flowing from the selected node device to the non-selected node device. The network device may store the QoE metrics and determine counter QoE metrics for data flows flowing from the non-selected node device to the selected node device.
