Embodiment Construction

[0049] As mentioned in the background technology, the existing control configuration scheme is cumbersome and inconvenient to update. In order to solve this problem, the present invention proposes an automatic discovery and configuration method for the controller, enabling an automatic discovery control on the switch The ability of the controller, by sending free ARP packets to the automatically discovered controller, synchronize itself with the ARP entry on the controller, and establish an Openflow session based on the entry, and the controller automatically downloads to the switch through the Openflow session Send the information of the main controller and standby controller to which the switch should belong, and realize the automatic discovery function of the switch for the newly added controller and the automatic distribution function of the controller.

[0050] Such as Figure 6 As shown, it is a schematic flowchart of a method for automatic discovery and configuration of...

Abstract

The embodiment of the invention discloses an autodiscovery and configuration method for a controller, and equipment. Through adoption of the technical scheme provided by the embodiment of the invention, a switch added with a capability of discovering the controller automatically synchronizes address resolution protocol (ARP) table items of the switch and the controller through sending free ARP messages to the automatically discovered controller, and establishes an Openflow session according to the table items; the controller automatically sends information of a master controller and a standby controller to the switch through the Openflow session, wherein the switch is assigned to the master controller and the standby controller, so that the switch can automatically discover a newly added controller; furthermore, according to principles such as load share, the controller can adjust the master controller and the standby controller which the switch is assigned to, so that the automatic configuration function of assigning the switch to a backup set can be realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a controller automatic discovery and configuration method and equipment. Background technique [0002] OpenFlow is a communication interface standard between a controller and a forwarding layer defined in an SDN (Software Defined Network, software-defined network) architecture. OpenFlow allows direct access and manipulation of the forwarding plane of network devices, which may be physical or virtual. [0003] The idea of ​​OpenFlow is to separate the control plane and the data plane, and use standard protocols to communicate between the two; the data plane uses a flow-based method for forwarding. [0004] The OpenFlow network is composed of OpenFlow Switch (OpenFlow network device) and OpenFlow Controller (OpenFlow controller) through OpenFlow Channel (OpenFlow channel), such as figure 1 Shown is a schematic structural diagram of an OpenFlow network in the prior art. ...
