Abstract: This application provide a data flow processing method and a device. A host determines a priority corresponding to a first data flow to be sent to a switch, and adds the priority to the first data flow to generate a second data flow that includes the priority. The host sends the second data flow to the switch, so that the switch processes the second data flow according to the priority of the second data flow. A host assigns a priority to a data flow, and the switch does not need to determine whether the data flow is an elephant flow or a mouse flow, thereby saving hardware resources of the switch. The switch does not need to determine the priority of the data flow, thereby processing the data flow in a timely manner.

Abstract: A network device checks forwarding tables of routers in a network by sending check packets designed to reach a target router via label-forwarding. The network device determines a forwarding path from itself to a destination IP address, with the target router on the forwarding path and at N hops from itself. The network device then generates and sends a check packet having a label stack with N link labels correspond to the hops and a TTL value set to N+1. When the check packet is routed by the target router to a next-hop node of the target router, the TTL value is deducted to 0, causing the next-hop node to send a notification message to the network device. Based on the identity of the next hop node, the network device determines whether the forwarding table of the target router is correct.

Abstract: In a fault root cause determining method, a management device obtains a fault feature of a target network in which a fault occurs. The fault feature is determined based on a knowledge graph of the target network in which the fault occurs. The knowledge graph includes a network entity and an abnormal event entity. The abnormal event entity is connected to an abnormal network entity. The abnormal network entity is a network entity that generates an abnormal event in the target network. The abnormal event entity is configured to indicate the abnormal event generated by the abnormal network entity. A type of the network entity is a network device, an interface, a protocol, or a service. The management device determines a fault root cause of the target network based on the fault feature.

Abstract: A network performance detection apparatus collects, based on identification information of a received data packet, statistics on data packets having the same identification information to obtain packet block information corresponding to the identification information and sends the packet block information to a second device when statistics collection of the packet block information corresponding to the identification information is completed to determine packet block quality information corresponding to the identification information. The identification information includes a flow identifier and a block identifier. The flow identifier includes a source Internet Protocol (IP) address, a source port, a destination IP address, and a destination port of the data packet. The block identifier is a higher N-bit value of an IP identity (IPID) field in the data packet.
