The SDN (Software Defined Network) technology separates functions of Network control and Network forwarding by a distributed architecture concept, and this way makes Network control programmable and can more flexibly control Network traffic. Specifically, the SDN strips the control plane in each device and puts the control plane into an SDN controller, and the controller centrally manages all devices on the forwarding path through a unified instruction. The controller knows the topology of the whole network, knows all necessary information in the forwarding process, and upper layer Application programs can also be controlled in a programmable mode through an Application Programming Interface (API) Interface provided by the controller, so that a large amount of manual configuration can be eliminated.
The current SDN vendors are many, such as SDN, tsntd, open source OVN (OpenVirtual Networking, openVirtual network), OVN is a light SDN controller, ICE in the shovers, and so on.

Detailed Description
The core of the invention is to provide a network control method based on a cloud platform, which supports a network virtualization component to adapt to different SDN controllers and can normally complete network function control.
In order that those skilled in the art will better understand the disclosure, reference will now be made in detail to the embodiments of the disclosure as illustrated in the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a cloud platform-based network control method according to the present invention, where the cloud platform-based network control method can be applied to an SDN adapter, and includes the following steps:
step S101: and receiving a network function control instruction.
Specifically, the user may send the network function control instruction to the cloud platform as needed. The specific content of the network function control instruction may be selected as needed, and may be various instructions related to network control, for example, in a specific occasion, a user needs to create a network on the cloud platform, and the network function control instruction is specifically a network creation instruction. Of course, in other specific cases, there may be other types of network creation instructions.
Considering that the cloud platform generally provides a front-end page for the user, the user can send the network function control instruction to the front-end page, and the operation is convenient. Correspondingly, the SDN adapter may receive the network function control instruction based on the front-end page, that is, step S101 may specifically be: and receiving a network function control instruction issued by a front-end page. For example, in the above example, when the network function control instruction is specifically a network creation instruction, the front end may call the cloud platform to create a network interface, and further send the network creation instruction to the SDN adapter.
Step S102: determining each SDN implementation class in the cloud platform; wherein the SDN implementation class is used for performing instruction conversion to obtain instruction contents identified by a corresponding SDN controller.
According to the application, a plurality of SDN implementation classes are required to be set in a cloud platform, wherein the SDN implementation classes can also be called SDN processing modules and can be used for instruction conversion. Fig. 2 of the present application is an architecture diagram of adapting 2 SDN controllers in a specific embodiment, where SDN implementation classes in fig. 2 specifically include 2, that is, OVN implementation classes and ICE implementation classes.
Because the network function control instruction cannot be directly identified by the SDN controller, and for the same network function control instruction, there is a certain difference in processing logic of different SDN controllers, it is necessary to implement instruction conversion by the SDN implementation class. That is, after instruction conversion by the SDN implementation class, instruction content that can be recognized by the corresponding SDN controller may be obtained. Certainly, since the scheme of the application needs to support multiple SDN controllers, different SDN controllers have different processing logics, multiple SDN implementation classes also need to be set, and different SDN implementation classes adopt different processing logics, that is, for a specific SDN implementation class, the SDN implementation class has a code logic of its own, and the instruction content obtained after conversion by the SDN implementation class can be identified by a corresponding SDN controller.
Step S103: and inquiring the type of the SDN controller currently adapted to the network virtualization component, and selecting the SDN implementation class corresponding to the type based on the type of the SDN controller.
The network virtualization component may implement virtualization of a network, and a specific type of the network virtualization component may be set and selected according to a need, for example, in the embodiment of fig. 2, the network virtualization component is a neutron. neutron is a network virtualization component of Open Stack, responsible for the virtualization of network parts. For the adaptation work of the SDN controller, the adaptation work is completed in neutron, and after the adaptation is completed, the network control function is taken over by the SDN controller.
The Open Stack is an Open-source cloud computing management platform project, is a combination of a series of software Open-source projects, and can provide extensible and elastic cloud computing services for private clouds and public clouds. In other specific situations, other types of cloud computing management platforms besides Open Stack may be used without affecting the implementation of the present invention. OpenStack supports virtual machine software or containers such as KVM, xen, lvc, docker, etc., and defaults to KVM. Other types of virtual machine software or containers may also be supported by the installation driver. OpenStack is developed by adopting Python language and follows Apache open source protocol, so that compared with Cloud Stack, the OpenStack is lighter in weight and higher in efficiency.
It should be noted that the present application allows network virtualization components to adapt to different SDN controllers, for example, in fig. 2, a network virtualization component neutron may adapt to OVN controller or ICE controller, but in a specific case, the SDN controller currently adapted by a network virtualization component is determined, that is, in fig. 2, either OVN controller or ICE controller is currently adapted.
Further, in one embodiment of the present invention. The cloud platform comprises 1 or more network virtualization components, and each network virtualization component is provided with a type of an SDN controller which is adapted to the network virtualization component.
As described above, in a particular scenario, the SDN controller to which a network virtualization component is currently adapted is determined. In the embodiment, 1 or more network virtualization components are allowed to be arranged in the cloud platform and are uniformly managed by the cloud platform.
For example, in a specific case, 3 network virtualization components are provided, which are called neutron-1, neutron-2 and neutron-3, respectively, and for the 3 network virtualization components, the types of SDN controllers respectively adapted to the 3 network virtualization components may not be limited, for example, neutron-1 is adapted to be OVN controller, neutron-2 is adapted to be ICE controller, and neutron-3 is adapted to be OVN controller.
In a specific embodiment of the present invention, the determining of each SDN implementation class in the cloud platform described in step S102 may specifically include:
determining each SDN implementation class in the cloud platform, and constructing a map comprising each SDN implementation class;
correspondingly, the selecting of the SDN implementation class corresponding to the type described in step S103 may specifically include:
and selecting the SDN implementation class matched with the type from the map.
In this practical application, after verification and participation, the SDN adapter may determine each SDN implementation class in the cloud platform, and then process the SDN implementation classes, that is, may construct a map including each SDN implementation class, so that retrieval may be performed in the map subsequently. For example, for the example of fig. 2, the key in the map is OVN and ICE, and the Value corresponding to each key is OVN implementation class and ICE implementation class, which indicates that 2 SDN implementation classes are set in the cloud platform.
And subsequently querying the type of the SDN controller currently adapted to the network virtualization component, for example, querying that the type of the SDN controller currently adapted to the network virtualization component is ICE, and then selecting an SDN implementation class matched with the type from the map based on the type of the SDN controller. Namely, an ICE is input and matched with a map, and an SDN implementation class matched with the type is determined to be the ICE implementation class.
Step S104: and sending the network function control instruction to the selected SDN implementation class, so that the SDN implementation class sends the instruction content obtained after instruction conversion to the SDN controller through a network virtualization component, and the SDN controller executes the instruction content.
Since in step S103, the SDN implementation class corresponding to the type of the SDN controller currently adapted by the network virtualization component is selected, the received network function control instruction may be sent to this SDN implementation class.
For example, in the above example, the type of the SDN controller currently adapted by the network virtualization component is an ICE controller, and therefore, the SDN implementation class matching the type is determined to be specifically the ICE implementation class. Then in the example of fig. 2, the network function control instructions may be sent to the right ICE implementation class.
In a specific embodiment of the present invention, the sending the network function control instruction to the selected SDN implementation class described in step S104 may specifically include:
and sending the network function control instruction to the selected SDN implementation classes based on the annotation identification of each SDN implementation class in the cloud platform.
In the implementation manner, a user-defined annotation can be set for each SDN implementation class in the cloud platform, so as to play a role of identification, and identify which SDN each SDN implementation class is respectively adapted to. The code of the specific annotation identifier can be set and adjusted as required.
And after the network function control instruction is sent to the selected SDN implementation class, the SDN implementation class performs instruction conversion. For example, in the above example, the network function control instruction is sent to the ICE implementation class on the right side of fig. 2. The ICE implementation class may perform instruction translation and the resulting instruction content may be recognized by the ICE controller. The network virtualization component may send the instructional content to the ICE controller to cause the ICE controller to execute the instructional content. For example, in the above example, the network function control instruction is specifically a network creation instruction, and at this time, the ICE controller may create a network according to the instruction content.
In addition, in practical application, after the SDN controller executes the instruction content, the execution result may be fed back to the cloud platform through the network virtualization component, so that a user may know whether the network function control instruction issued before is successfully executed through the cloud platform.
According to the scheme, 1 network virtualization component of the cloud platform can adapt to SDN controllers of different types, namely, an adaptation scheme of 1 to multiple SDNs is achieved, and therefore the cloud platform can adapt to different SDN controllers only by setting one set of codes. That is, for 1 network virtualization component, no matter what is deployed at the bottom layer is OVN controller, ICE controller, or what is called SND controller, hua san SDN controller, etc., the function from the front end page to the network can be operated normally.
In an embodiment of the present invention, the method may further include:
after querying the type of the SDN controller currently adapted by the network virtualization component, when the SDN implementation class corresponding to the type is not matched, returning to perform the operation of step S102.
In this embodiment, it is considered that in some cases, after querying the type of SDN controller currently adapted by the network virtualization component, a situation that the SDN implementation class corresponding to the type cannot be matched may occur.
For example, after querying the map in the above example, it is found that any 1 key in the map is not consistent with the type of SDN controller currently adapted by the network virtualization component. The reason for this may be that the SDN implementation classes set up in the cloud platform do not cover the SDN controller that the network virtualization component is currently adapted to. Of course, the abnormal reasons may also be caused, for example, when the operation of step S102 is performed, the determined SDN implementation classes in the cloud platform are incomplete, and when the operation of step S103 is performed, a type of an SDN controller currently adapted to the network virtualization component is queried to be incorrect.
For this reason, in this embodiment, when a mismatch is found, the operation in step S102 is returned to determine each SDN implementation class in the cloud platform again, and then, when step S103 is executed, the type of the SDN controller currently adapted to the network virtualization component may be queried again. It can be seen that in the embodiment, matching failure caused by partial abnormal conditions can be dealt with, and the reliability of the scheme is improved.
Further, in a specific embodiment of the present invention, after the operation of determining each SDN implementation class in the cloud platform is returned, and the type of the SDN controller currently adapted to the network virtualization component is re-queried, when the SDN implementation class corresponding to the type is not yet matched, the network control process based on the cloud platform is ended, and an error prompt is returned.
In this embodiment, after the operations of step S102 and step S103 are re-executed, if the SDN implementation class corresponding to the type of the SDN controller currently adapted to the network virtualization component is still not matched, each SDN implementation class set in the cloud platform may be generally described, and the SDN controller currently adapted to the network virtualization component is not actually covered, so that the network control process based on the cloud platform at this time may be performed, and an error prompt is returned.
In practical application, the returned error prompt may carry a specific error reason, for example, in this embodiment, it may be prompted that each SDN implementation class set in the cloud platform may not cover an SDN controller currently adapted to the network virtualization component, thereby causing an error. The staff may perform corresponding adjustment according to the error prompt, for example, adjust an SDN controller adapted to the network virtualization component, that is, select an SDN controller that can be supported by the cloud platform. As another example, add the SDN implementation class required by the SDN controller in the cloud platform.
By applying the cloud platform-based network control method provided by the embodiment of the invention, each SDN implementation class is set in the cloud platform, and the SDN implementation class can perform instruction conversion to obtain the instruction content identified by the corresponding SDN controller, namely the SDN implementation class can perform instruction conversion so that the obtained instruction content can be identified by the corresponding SDN controller. The SDN adapter can inquire the type of the SDN controller currently adapted to the network virtualization component, and select the SDN implementation class corresponding to the type based on the type of the SDN controller, that is, the SDN implementation classes selected by the SDN adapter are different when the types of the SDN controller currently adapted to the network virtualization component are different, and the different SDN implementation classes have respective processing logic. After an SDN implementation class corresponding to the SDN controller type is selected, the received network function control instruction is sent to the SDN implementation class, so that the SDN implementation class sends the instruction content obtained after instruction conversion to an SDN controller through a network virtualization component, and the SDN controller can execute the instruction content, namely, the requirement of the network function control instruction is completed. To sum up, the scheme of the application supports the network virtualization component to adapt to different SDN controllers, and can normally complete network function control.
