Abstract

The invention provides a cross-regional connection method and device for SDN controllers and forwarding equipment. The method includes: obtaining region information of all SDC controllers and all forwarding equipment in multiple regions, wherein all the SDC controllers include this equipment; determining target forwarding equipment matched with this equipment according to the region information; and establishing a connection with the target forwarding equipment. The technical scheme of the cross-regional connection method can configure the region information for the SDC controller and the forwarding equipment respectively, enabling the SDN controllers to determine the target forwarding equipment matched with this equipment according to the region information, avoiding occurrence of a situation of cross-regional control, reducing control risks, and thereby enhancing stability of a system.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and apparatus for connecting a cross-regional SDN controller and a forwarding device. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new type of network architecture, which adopts a new design concept, separates the control plane and data plane, and transfers the control plane that was previously solidified in the network equipment to the accessible computing equipment. In this way, the flexible control of network traffic is realized, which provides a good platform for the innovation of core network and application. [0003] SDN technology can well meet the needs of data center network centralized management, flexible forwarding, virtual machine deployment, and virtual machine migration. Therefore, SDN technology has been more and more applied in data centers. [0004] In a cross-regional networking en...
