Abstract: A routing method and a device to provide a routing path that satisfies a quality of service (QoS) requirement, where the routing method includes performing QoS measurement on a path between the first routing node and a reachable adjacent routing node, to obtain a QoS parameter set of the path between every two adjacent routing nodes, reporting the QoS parameter set to the control node, receiving one or more routing tables of routing performed from the first routing node to the other routing node that are delivered by the control node, and receiving a packet, determining, from the one or more routing tables, a routing table corresponding to an identifier of the packet, and forwarding the received packet based on the routing table.
