Cluster system of SDN controllers and issuing configuration method

Abstract

The invention provides a cluster system of SDN controllers and an issuing configuration method. The issuing configuration method comprises the following steps of: A, receiving an execution message request; B, writing an execution message of the request into a message queue; C, distributing the execution message received in the step A to all the SDN controllers by means of a message queue; D, enabling each SDN controller to process the execution message request; E, enabling the SDN controllers to judge whether current equipment is managed by the SDN controllers or not, and if so, issuing configuration to the equipment; and if not, ending the operation. The issuing configuration method has the beneficial effects that the configuration issuing of all equipment is controlled by a certain SDN controller, thereby solving a problem that the configuration issuing of the equipment is mutually exclusive; each set of equipment is controlled by one SDN to be responsible for issuing configuration,so that the minimum ssh connection number is ensured; and consistency among the SDN controllers is ensured, and the pressure of the controllers for controlling the equipment is shared.

Description

Technical field [0001] The invention belongs to the technical field of SDN controller issuing configuration, and in particular relates to a cluster system issuing configuration method of an SDN controller. Background technique [0002] SDN (Software Defined Network) network is a new type of network architecture that centralizes control of the resources of the entire network, which is of great significance for improving the delivery of network resources. Some manufacturers use a single SDN controller, which has the advantage of simple control. But there are also fatal shortcomings. The current controller is down, causing the entire network to be in an unmanaged state. Most manufacturers use cluster SDN controllers to solve the problems of controller stability and poor control efficiency. The number of SDN controllers is the base. The purpose of the base number of controllers is to quickly elect the main controller. The data synchronization method of the SDN controller is as fol...

AI Technical Summary

Problems solved by technology

If each SDN controller sends the configuration to the device, there will be the following problems: the situation that the two controllers operate the device are mutually exclusive. For example, there are two operations, one is to delete the configuration, and the other is to modify the configuration. If It is to delete the configuration first, and modifying the configuration will report an error and cannot be executed; each device is issued by the SDN controller. When the number of SDN controllers increases, there are multiple SDN controllers to send configurations to the device. , the distribution of configuration requires ssh connection, and the number of ssh connections of the device is limited.
