Abstract
The application provides a cluster system of SDN controllers and a distribution configuration method, wherein the distribution configuration method comprises the following steps: A. receiving an execution message request; B. writing the requested execution message into a message queue; C. the message queue distributes the execution message received in the step A to all SDN controllers; D. each SDN controller processes the execution message request; e, judging whether the current equipment is managed by the SDN controller or not by the SDN controller, and if so, issuing configuration to the equipment; if not, the operation is ended. The application has the beneficial effects that: because the configuration issuing of all the devices is controlled by a certain SDN controller, the problem of mutual exclusion of the configuration issuing of the devices is solved; each device is responsible for issuing configuration by SDN control, so that the minimum ssh connection number is ensured; and consistency among SDN controllers is ensured, and pressure of control equipment of the controllers is shared.
Description
Technical Field
The application belongs to the technical field of issuing configuration of SDN controllers, and particularly relates to a cluster system issuing configuration method of an SDN controller.
Background
SDN (Software Defined Network, software defined networking) network is a novel network architecture, and has very important significance for improving network resource delivery by centrally controlling resources of the whole network. Some manufacturers use a single SDN controller, which has the advantage of simple control. But also has the fatal disadvantage that the current controller is down, resulting in the whole network being in an unmanaged state. Most manufacturers adopt cluster SDN controllers to solve the problem of poor stability and control efficiency of the controllers, and the number of the SDN controllers is a base number. The purpose of the radix number controllers is to rapidly elect the master controller. The manner of data synchronization of the SDN controller is as follows: externally provided with data is locally cached data, which is done to improve the performance of the controller. If each SDN controller performs a downstream configuration on a device, the following problems may exist: the situation that two controllers operate the mutual exclusion of equipment cannot be solved, for example, two operations exist, namely, one is deleting configuration and the other is modifying configuration, if the deleting configuration is executed first, the modifying configuration is reported to be wrong, and the deleting configuration cannot be executed; each device is configured by issuing an SDN controller, when the number of SDN controllers is increased, a plurality of SDN controllers exist for issuing the configuration to the devices, the issuing configuration needs to perform ssh connection, and the number of the ssh connections of the devices is limited.
Disclosure of Invention
In view of the above, the present application is directed to a cluster system and a distribution configuration method of an SDN controller, so as to solve the above-mentioned drawbacks.
In order to achieve the above purpose, the technical scheme of the application is realized as follows:
the cluster system of the SDN controllers comprises SDN cluster controllers, wherein each SDN cluster controller comprises a plurality of SDN controllers, and each SDN controller is connected with a plurality of devices.
The application also provides another embodiment, a cluster system issuing configuration method of the SDN controller, which comprises the following steps:
an SDN cluster controller receives an execution message request;
B. writing the requested execution message into a message queue;
C. the message queue distributes the execution message received in the step A to all SDN controllers;
D. each SDN controller processes the execution message request;
E. each SDN controller judges whether the current equipment is managed by the SDN controller, and if so, the configuration is issued to the equipment; if not, the operation is ended.
Compared with the prior art, the cluster system and the issuing configuration method of the SDN controller have the following advantages:
the cluster system and the issuing configuration method of the SDN controller solve the problem of mutual exclusion of the issuing configuration of the devices because the configuration issuing of all the devices is controlled by one SDN controller; each device is responsible for issuing configuration by SDN control, so that the minimum ssh connection number is ensured; and consistency among SDN controllers is ensured, and pressure of control equipment of the controllers is shared.

Detailed Description
The application will be described in detail below with reference to the drawings in connection with embodiments.
The cluster system of the SDN controllers comprises SDN cluster controllers, wherein each SDN cluster controller comprises a plurality of SDN controllers, and each SDN controller is connected with a plurality of devices.
The application also provides another embodiment, a cluster system issuing configuration method of the SDN controller, which comprises the following steps:
an SDN cluster controller receives an execution message request;
B. writing the requested execution message into a message queue;
C. the message queue distributes the execution message received in the step A to all SDN controllers;
D. each SDN controller processes the execution message request;
E. each SDN controller judges whether the current equipment is managed by the SDN controller, and if so, the configuration is issued to the equipment; if not, the operation is ended.
In order to solve the defect of cluster issuing configuration of SDN controllers existing at present, the application provides a regional load balancing method, wherein each SDN controller controls a part of devices, only the devices controlled by the SDN can issue configuration to the SDN controllers, and other SDN controllers cannot issue configuration to the SDN controllers. When there is an executed message, a request is stored in a message queue, the message queue distributes the request to all controllers, each controller executes the action, and when the configuration is issued, only the current SDN controller can issue the managed device.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
