Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A cloud management platform and controller integration method according to an embodiment of the present invention is described below with reference to fig. 2.
Fig. 2 is a flowchart of an embodiment of a method for integrating a cloud management platform and a controller according to the present invention. As shown in fig. 2, the method of this embodiment includes:
step S202, the message queue module receives network change data sent by the cloud management platform.
The network operation of the user is oriented to the cloud management platform, and the network operation can be, for example, adding, moving network equipment, modifying network configuration and the like. The network operations of the user generate corresponding network change data.
After the cloud management platform generates the network change data, the data is sent to the controller through the message queue module.
The cloud management platform may be OpenStack, for example.
Step S204, the message queue module stores the network change data.
The message queue module is a container used for storing messages in the transmission process of the messages. The message queue module stores the network change data until it is ensured that the controller has received the network change data, so as to prevent the data from being lost during transmission.
In step S206, the message queue module sends network change data to the controller in response to the data acquisition request sent by the controller, so that the controller configures the network device according to the network change data.
The controller may periodically send a data acquisition request to the message queue module, or may send a data acquisition request to the message queue module according to other trigger conditions.
The controller may be an Opendaylight controller, for example.
Step S208, if the message queue module does not receive the receiving feedback sent by the controller, the message queue module sends the network change data to the controller again.
The cloud management platform and the controller communicate in a reliable mode through the message queue module. To ensure that the data is delivered, the message queue module waits for feedback from the controller after sending the data. For example, it may be set that, when the reception feedback sent by the controller is not received within a preset time, the message queue module resends the network change data to the controller.
In one embodiment, the message queue module may delete the transmitted network change data if the message queue module receives feedback from the controller. In addition, the message queue module may store network change data that has been successfully transmitted for a period of time and periodically delete the network change data.
By adopting the message queue module to receive and store the network change data sent by the cloud management platform and continuously retransmitting the network change data before the controller confirms the reception, the controller can be ensured to accurately and completely acquire the network change operation received by the cloud management platform, so that the controller can accurately configure the network, and the usability of the cloud management platform and the controller integration is improved.
In the above embodiment, the Message queue module may be implemented based on AMQP (Advanced Message Queuing Protocol). The AMQP is an open standard of an application layer protocol, is a message-oriented middleware design, is not limited by different development languages and product types of the middleware, and has high flexibility.
In one embodiment, the message queue module may receive network change data sent by the cloud management platform through the AMQP and send the network change data to the controller through the AMQP.
As shown in fig. 3, the cloud management platform writes network change data B generated by a network operation of a user into the tenant network database, and sends the network change data B to the controller through the AMQP-based message queue module. And when the controller is unavailable, the message queue module finds that network change data B cannot be delivered. At this time, the message queue module will continue to store the network change data and resend the data, and when the controller enters the available state and receives the network change data B resent by the message queue module, the controller will send a receiving feedback to the message queue module so that the message queue module does not resend the data any more.
Therefore, the content of the tenant network database corresponding to the cloud management platform is consistent with the content of the virtual/physical network database corresponding to the controller, and the controller can accurately and completely configure or change the network according to the operation of the user.
By adopting the method, the reliability of data transmission is improved, and the message queue module can quickly respond to the cloud management platform, so that the system efficiency is improved.
Between the cloud management platform and the controller, only one message queue module can be adopted for transferring information. In addition, in order to further improve the reliability of the system, a message queue system composed of a plurality of message queue modules can be used as a data channel to integrate the cloud management platform and the controller.
In one embodiment, the system is serviced by a master message queue module and a slave message queue module together. In a normal state, the main message queue module is adopted to receive network change data sent by the cloud management platform, store the network change data, and respond to a data acquisition request sent by the controller and send the network change data to the controller. The slave message queue module may periodically synchronize network change data in the master message queue module.
When the master message queue module is unavailable, the slave message queue module can be converted into the master message queue module in response to the switching instruction, and serves the cloud management platform and the controller, namely, the original slave cloud management platform is adopted to receive network change data sent by the cloud management platform, the network change data is stored, and the network change data is sent to the controller in response to a data acquisition request sent by the controller.
Thus, the reliability of data transmission can be further increased.
In another embodiment, the message queue module is deployed in a cluster manner, that is, the message queue cluster is used for serving the cloud management platform and the controller, and the message queue cluster is provided with a plurality of message queue modules and a load balancing module.
The load balancing module can receive the network change data sent by the cloud management platform and distribute the network change data to the message queue module in the cluster for processing.
The load balancing module may select the message queue module according to at least one of network change data, attributes of each message queue module in the message queue module cluster, and a current state of each message queue module in the message queue module cluster.
The attributes of the message queue module may be, for example, the computing power, the storage space of the message queue module, and the current state of the message queue module may be, for example, whether it is currently free, the number of message entries to be processed, and so on. Therefore, the network change data can be more efficiently transmitted to the controller, and the efficiency of the system is improved.
