Provided are a routing method, and a relevant device and system, which are applied to a network with a separation of controlling and forwarding. The network with a separation of controlling and forwarding comprises a control device and a forwarding device, and the control device controls the forwarding device. The method comprises: configuring a first path and a second path in charge of load sharing to a data flow, configuring a third path in charge of rerouting protection, generating a first group of table items for instructing the forwarding device to use the first path and the second path as load sharing paths and use the third path to perform rerouting protection on the first path and the second path, and generating a flow table item for indicating the execution of going toward the first group of table items. The present invention can solve the problem that fast rerouting protection cannot be implemented when there are a plurality of load sharing paths in a network and any one of the load sharing paths has a fault, effectively reduce the lose rate of packets and improve the processing efficiency when there is a fault, thereby ensuring that the packets can be forwarded normally. |
