Abstract: According to an example of the present disclosure, in a method for calculating a spanning tree, a SDN controller virtualizes a plurality of SDN forwarding devices in a SDN as a virtual network bridge device, performs interaction of spanning tree protocol (STP) data unit packets with an external network device through the virtual network bridge device to calculate a spanning tree between the virtual network bridge device and the external network device according to a STP running on the SDN controller and information carried in a STP data unit packet from the external network device.
