Disclosed are a method for creating a port group, an SDN controller and a network system. The method comprises: a first SDN controller generates a specified identifier according to a device identifier of a first forwarding device, a device identifier of a last forwarding device and a device identifier of a specified forwarding device in a preset path; and the first SDN controller sends the specified identifier to a second SDN controller, so that the second SDN controller creates, on the specified forwarding device, a specified port group corresponding to the specified identifier. According to this embodiment, the first SDN controller only needs to interact with the second SDN controller once, so as to create a port group on the specified forwarding device directly controlled by the second SDN controller, the number of interactions between the SDN controllers in the port creation process is reduced and the port group creation process is simple. |
