Abstract
The method is applied to an SDN network, where the SDN network includes one target computing apparatus and a plurality of openflow switches. The target computing apparatus communicates with the plurality of openflow switches. The method includes: receiving, by the target computing apparatus, a first bridge protocol data unit (BPDU) packet sent by a first openflow switch, where the first BPDU packet carries a device identifier and a port identifier; generating, by the target computing apparatus, a feedback packet based on the first BPDU packet, where the feedback packet includes spanning tree protocol information of a conventional switching device, and carries the port identifier; and sending, by the target computing apparatus, the feedback packet to the first openflow switch based on the device identifier.
