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.
