Embodiment Construction

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] In the embodiment of the present invention, the designated forwarding device refers to the forwarding device on which the SDN controller intends to create a port group or perform port group-related operations; the first SDN controller refers to the SDN controller that indirectly controls the designated forwarding device ; The second SDN controller refers to the SDN controller that directly controls the designated forwarding device.

[0046] For example, in the...

Abstract

The invention discloses a method of creating a port group in SDN, SDN controllers, and a network system. The method is characterized in that a first SDN controller is used to generate a specified identification according to a device identification of a first forwarding device of a default route, a device identification of a last forwarding device, and a device identification of a specified forwarding device; the first SDN controller is used to transmit the specified identification to a second SDN controller, and then the second SDN controller is used to create the specified port group corresponding to the specified identification on the specified forwarding device. By adopting the embodiment provided by the invention, the first SDN controller is only required to be interacted with the second SDN controller once to create the port group on the specified forwarding device, which is directly controlled by the second SDN controller, and therefore the number of the times of the interaction between the SDN controllers during the port group creating process is less, and the port group creating process is simple.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for creating a port group in SDN, an SDN controller and a network system. Background technique [0002] A Software Defined Network (SDN for short) is a network composed of an SDN controller and a forwarding device, wherein the forwarding device accesses the SDN through the SDN controller. In SDN, the forwarding plane is separated from the control plane. The forwarding device accesses the SDN through the SDN controller and is used to complete data transfer. The SDN controller controls the forwarding process and forwarding rules of the forwarding device connected to the SDN, and the forwarding After the device completes data forwarding, other SDN controllers can also control the forwarding devices connected to the SDN through the SDN controller through the SDN controller. When there are multiple SDN controllers in the SDN, each SDN controller can directly control the forwarding ...
