Disclosed is a method of fast path configuration and fault recovery in a software-defined networking environment. A software-defined networking controller can be configured to determine the path of flow from a first host to a second host and to transmit information on the path of flow to a first networking device on the path of flow. Meanwhile, the networking device can be configured to receive a packet from a preceding networking device on the path and to add a flow entry to a flow table, which is managed by the networking device, by referring to path information of the flow included in the packet. Also, the networking device can be configured to update the path information of the flow by removing items corresponding to the networking device from the path information of the flow included in the packet and transmit, to the next networking device on the path, the packet including the updated path information of the flow. |
