The hardware block diagram shown in fig. 1 may be used not only as an exemplary block diagram of the computer terminal 10 (or mobile device) described above, but also as an exemplary block diagram of the server described above, and in an alternative embodiment, fig. 2 shows, in block diagram form, one embodiment of using the computer terminal 10 (or mobile device) shown in fig. 1 described above as a computing node in a computing environment 201.

Each computing node contains local processing and memory resources and end user 202 may run applications or store data remotely in computing environment 201. The application may be provided as a plurality of services 220-1, 220-2, 220-3, and 220-4 in computing environment 201, representing services "A", "D", "E", and "H", respectively.

Ingress gateway 230 may include a corresponding agent to handle provisioning and/or request for service 220 (one or more services provided in computing environment 201).

Services 220 are provided or deployed in accordance with various virtualization techniques supported by computing environment 201. In some embodiments, service 220 may be provided in accordance with Virtual Machine (VM) based virtualization, container based virtualization, and/or the like. Virtual machine-based virtualization may be the emulation of a real computer by initializing a virtual machine, executing programs and applications without directly touching any real hardware resources. While a virtual machine virtualizes a machine, according to container-based virtualization, a container may be started to virtualize the entire Operating System (OS) so that multiple workloads may run on a single operating system instance.

In one embodiment based on container virtualization, several containers of service 220 may be assembled into one POD (e.g., kubernetes POD). For example, as shown in FIG. 2, the service 220-2 may be equipped with one or more PODs 240-1, 240-2, …,240-N (collectively PODs 240).

The computing environment may be a cloud computing environment, and the allocation of resources is managed by a cloud service provider, allowing the development of functions without considering the implementation, adjustment or expansion of the server. The computing environment allows developers to execute code that responds to events without building or maintaining a complex infrastructure. Instead of expanding a single hardware device to handle the potential load, the service may be partitioned to a set of functions that can be automatically scaled independently.

Grid agent 303 and grid agent 305 form a data plane layer (dataplane) of service grid 300. Wherein grid agent 303 and grid agent 305 are each in the form of a container/process 304, container/process 304 may receive a request 312 for conducting a commodity query service, grid agent 306 is running, and grid agent 303 and application service instance a may communicate bi-directionally, and grid agent 305 and application service instance B may communicate bi-directionally. In addition, two-way communication is also possible between the grid agent 303 and the grid agent 305.

In the above operating environment, the present application provides an SDN-based network configuration information issuing method as shown in fig. 4. Fig. 4 is a flowchart of a network configuration information issuing method based on SDN according to an embodiment of the present invention, as shown in fig. 4, the method may include the following steps:

Step S402, acquiring multiple sets of network configuration information from the software defined network SDN, where the network configuration information is used to characterize operations performed on the SDN.

In the technical solution provided in the above step S402 of the present invention, when the network is changed, the software defined network SDN generates the change configuration information, and obtains multiple sets of network change configuration information from the software defined network SDN, where the network change configuration information is used to characterize an operation performed on the SDN and may be used to represent an operation performed on the network by a user, for example, creating a virtual machine, adding a route, and so on.

Optionally, in a large-scale SDN network scenario (e.g., VPC network), a large amount of network reconfiguration information is generated every second, where the network reconfiguration information may be used to perform operations on its network by a user, such as creating a virtual machine, adding a route, etc., because the network reconfiguration information is functionally programmed by the SDN controller at the center, so that multiple sets of network reconfiguration information are obtained from the software defined network SDN.

Step S404, adding network feature data to each set of network configuration information to generate a plurality of sets of network configuration information, wherein the network configuration information is used for characterizing SDN network configuration enabling the operation to be effective in the SDN.

In the technical solution provided in the step S404 of the present invention, the network characteristic data at least includes: the network feature type is used for representing the type of the SDN network configuration, and the feature value is used for representing the attribute value of the SDN network configuration.

In this embodiment, a network feature type may be specified for different types of network configuration information, and the network feature type may be a non-duplicate value, such as 1,2,3, etc.; a non-repeating string is also possible, such as a flexible internet protocol address (Elastic IP Address, abbreviated as eip), a tunnel protocol (tunnel), etc.; for the network configuration information, a specific characteristic value calculation method is used according to the specified network characteristic type.

For example, in creating network configuration information under the network configuration information such as VPC, the network configuration information to be generated may be the VPC configuration of the VPC may be the address (vxlan id) of the virtual extended lan, where the network feature type of the VPC configuration is "VPC", and the feature value is vxlan id, for example, in a multi-tenant network (for example, VPC network) scenario, different VPCs of different tenants are isolated by using the virtual extended lan (virtual extensible local area network, abbreviated as vxlan) technology, and each VPC has a unique address of the virtual extended lan.

For another example, in the network on the cloud, the PUBLIC network address is a globally unique address, and in the network reconfiguration scenario that the user binds the PUBLIC network address to his virtual machine, the network configuration information to be generated is the binding relationship between the virtual machine and the PUBLIC network IP, which may be called PUBLIC network address configuration, and the network feature type of the PUBLIC network address configuration may be specified as "public_address" (for example, "public_ip"), and the feature value of the PUBLIC network address configuration is a value after the address is converted into integer.

After acquiring the plurality of sets of network configuration information, network feature data may be added to each set of network configuration information to generate a plurality of sets of network configuration information, where the network configuration information may be used to characterize an SDN network configuration that validates the operation in the SDN, where the network configuration information may include: protocol number (protocol number), protocol content (fields), network feature type (key type) and feature value (key value), which may be virtual private cloud (Vitual Private Cloud, simply referred to as VPC) configuration information, public network address configuration information, may be used to enable network configuration information of a user network to be actually validated, and configuration items generated on a device.

Optionally, in a large-scale SDN network scenario, a large amount of network reconfiguration information is generated every second, and the network reconfiguration information is functionally programmed by an SDN controller in the center, so as to generate network configuration information and send the network configuration information to the forwarding device through a protocol.

For example, the network configuration information under creation of the VPC network configuration information may be the VPC configuration information of the VPC, and the generated network configuration information may be an address (vxlan id) of the virtual extended lan.

Step S406, obtaining the network characteristic types and the characteristic values under the network characteristic types in the mutually independent multiple groups of network configuration information.

In the technical solution provided in the above step S406 of the present invention, when the network is changed, the SDN controller generates network configuration information, adds network feature data to each set of network configuration information, generates multiple sets of network configuration information, obtains the network feature types and feature values under the network feature types in the multiple sets of network configuration information that are independent of each other,

step S408, corresponding network configuration information is issued to the associated network equipment based on the acquired network feature type and the feature value under the network feature type.

In the technical solution provided in the above step S408 of the present invention, the SDN issues configurations having the same feature value and feature type, and issues network configuration information in batches to the associated network device, where the associated network device may be a cloud gateway device.

Optionally, the SDN obtains network configuration information to be issued, issues configurations with the same feature value and network feature type, and issues the configurations to the cloud gateway device in batches, where the issuing content may include the network configuration information and a version number of the configuration.

Acquiring multiple sets of network configuration information from the software defined network SDN through steps S402 to S408 in the present application, where the network configuration information is used to characterize operations performed on the SDN; adding network feature data to each set of network configuration information to generate a plurality of sets of network configuration information, wherein the network configuration information is used for characterizing SDN network configuration enabling the operation to be effective in the SDN, and the network feature data at least comprises: the network feature type is used for representing the type of SDN network configuration, and the feature value is used for representing the attribute value of the SDN network configuration; acquiring network feature types and feature values under the network feature types in mutually independent multiple groups of network configuration information; and issuing corresponding network configuration information to the associated network equipment based on the acquired network characteristic type and the characteristic value under the network characteristic type. That is, by adding the network feature type and the feature value to the network configuration information, the network configuration information of different feature values and network feature types are mutually independent, and when the network configuration information of a certain feature value fails to be issued, the issuing of the network configuration information of other feature values is not influenced, so that the reliability of issuing the network configuration information is ensured, the technical problem that the reliability of issuing the network configuration information cannot be ensured is solved, and the technical effect that the reliability of issuing the network configuration information can be ensured is realized.

The above-described method of this embodiment is further described below.

As an optional implementation manner, step S408, based on the obtained network feature type and the feature value under the network feature type, issues corresponding network configuration information to the associated network device, including: ordering multiple groups of network configuration information with the same network characteristic type and the same characteristic value; and at least sequentially issuing the ordered multiple groups of network configuration information to the associated network equipment.

In this embodiment, the SDN obtains network configuration information, orders the network configuration information with the same feature value and network feature type, and then issues the network configuration information in batches onto the associated network device.

Optionally, the SDN may record version numbers of the generated network configuration information according to a time sequence, where the version numbers start from 1, the first generated configuration version number is 1, then the generated configuration version numbers are sequentially 2,3,4, and so on, sort the network configuration information with the same feature value and network feature type according to the size of the version number (version), and sequentially issue the sorted multiple groups of network configuration information to the associated network device.

As an alternative embodiment, ordering multiple sets of network configuration information having the same network feature type and the same feature value includes: and ordering the multiple groups of network configuration information according to the version numbers of the multiple groups of network configuration information.

In this embodiment, the SDN obtains network configuration information, orders the network configuration information according to the order of version numbers from small to large for the network configuration information with the same feature value and network feature type, and then issues the network configuration information to the associated network device in batches, where the issue content includes the network configuration information and the version number of the network configuration information, and the version number is used to indicate what version the network configuration information is.

Optionally, the sequentially increasing version numbers are maintained for the configuration with the same network feature type and feature value, so as to achieve the purpose that different tenant configuration issues have no influence on each other.

Fig. 5 is a flowchart of a network configuration information issuing method based on SDN according to an embodiment of the present invention, as shown in fig. 5, the method may include the following steps:

step S502, acquiring multiple sets of network configuration information from the software defined network SDN by calling a first interface, where the first interface includes a first parameter, a parameter value of the first parameter is network configuration information, and the network configuration information is used to characterize an operation performed on the SDN.

In the technical solution provided in the above step S502 of the present invention, the first interface may be an interface for performing data interaction between the server and the client. The client may obtain multiple sets of network configuration information from the software defined network SDN by calling the first interface, where the network configuration information may be used to characterize an operation performed on the SDN, as a first parameter of the first interface to achieve the purpose of determining the network configuration information.

Step S504, adding network feature data to each set of network configuration information, and generating multiple sets of network configuration information, where the network configuration information is used to characterize SDN network configuration that makes the above operations take effect in the SDN.

Step S508, corresponding network configuration information is issued to the associated network equipment based on the obtained network feature type and the feature value under the network feature type, and an issuing result is obtained.

In the technical solution provided in the above step S506 of the present invention, the SDN issues configurations having the same feature value and network feature type, and issues network configuration information to the associated network device in batches, where the associated network device obtains an issue result, and the associated network device may be a cloud gateway device.

Optionally, the SDN obtains network configuration information to be issued, issues configurations with the same feature value and network feature type, issues the configurations to the cloud gateway device in batches, and the cloud gateway device obtains an issue result, where the issue result may include the network configuration information and a version number of the configuration.

Optionally, the platform outputs the issuing result by calling a second interface, where the second interface is used to output data of the issuing result.

In the embodiment of the invention, a plurality of groups of network transformation information are acquired from a Software Defined Network (SDN) by calling a first interface, wherein the first interface comprises a first parameter, the parameter value of the first parameter is network transformation information, and the network transformation information is used for representing the operation performed on the SDN; adding network feature data to each set of network configuration information to generate a plurality of sets of network configuration information, wherein the network configuration information is used for characterizing SDN network configuration enabling the operation to be effective in the SDN, and the network feature data at least comprises: the network feature type is used for representing the type of SDN network configuration, and the feature value is used for representing the attribute value of the SDN network configuration; acquiring network feature types and feature values under the network feature types in mutually independent multiple groups of network configuration information; based on the obtained network characteristic type and the characteristic value under the network characteristic type, corresponding network configuration information is issued to the associated network equipment, and an issuing result is obtained; and outputting the issuing result by calling a second interface, wherein the second interface comprises a second parameter, and the parameter value of the second parameter is the issuing result.

Example 2

The following describes further a preferred implementation manner of the foregoing method of this embodiment, specifically, an implementation method based on an SDN network configuration issue based on a feature value is illustrated.

In the related art, in a large-scale SDN network scenario (e.g., VPC network), a large amount of network configuration information is generated every second, where the network configuration information may be an operation performed on a network by a user, for example, a virtual machine is created, a route is added, and the network configuration information is functionally programmed by a central SDN controller, so as to generate network configuration information and send the network configuration information to a forwarding device through a protocol, for example, an OpenFlow protocol specifies a manner and a message format for the SDN controller to send configuration to the OpenFlow device.

When an SDN network generates a large number of network changes in a short time, an SDN controller needs to quickly send these configurations to a forwarding device, but the above method cannot ensure the reliability of the configuration delivery.

In order to solve the problems, the application provides a method for realizing SDN network configuration issuing based on characteristic values, wherein the network characteristic types and the characteristic values are added to the network configuration, the configurations with different characteristic values respectively maintain an independent version number which is gradually increased, the configuration can be issued to forwarding equipment through a version number mechanism, and when the configuration issuing of a certain characteristic value fails, the issuing of other characteristic value configurations is not influenced, so that the reliability of the network configuration issuing is realized.

In this embodiment, when the network changes, the SDN controller generates a network configuration, and when the network configuration is generated, the SDN controller maintains a version number (version) that is sequentially incremented for configurations having the same network feature type and feature value, where a piece of network configuration information may include: protocol number, protocol content, network feature type and feature value, wherein one network feature type can be specified for different types of network configuration information, and the network feature type can be a non-repeated numerical value (such as 1,2,3, etc.), or a non-repeated character string (such as eip, tunnel, etc.); for the network configuration information, a specific characteristic value calculation method is used according to the specified network characteristic type.

Optionally, in this embodiment, sequentially increasing version numbers are maintained by the configuration with the same network feature type and feature value, so as to achieve the purpose that different tenant configuration issues do not affect each other, where the SDN controller records the version numbers of the generated network configuration information according to time sequence, the version number starts from 1, the first generated configuration version number is 1, then the generated configuration version number is sequentially 2,3,4, and so on, so as to maintain one sequentially increasing version number for the network configuration information.

For example, in creating network configuration information under the network configuration information such as VPC, the network configuration information to be generated may be configured for the VPC of the VPC and may be an address (vxlan id) of a virtual extended lan, where the network feature type of the VPC configuration is "VPC", and the feature value is vxlan id, for example, in a multi-tenant network (e.g., VPC network) scenario, different VPCs of different tenants are isolated by using a virtual extended lan technology, and each VPC has a unique address of the virtual extended lan.

For example, in a network-on-cloud network, only one PUBLIC network address is used, and in a network reconfiguration scenario that a user binds a PUBLIC network address to a virtual machine of the PUBLIC network address, the network configuration information to be generated is a binding relationship between the virtual machine and a PUBLIC network IP, which may be called PUBLIC network address configuration, and a network feature type of the PUBLIC network address configuration may be defined as a "public_address" (for example, "public_ip"), and a feature value of the PUBLIC network address configuration is a value after the address is converted into an integer.

In this embodiment, the SDN controller obtains the configuration that is not yet issued, orders the network configuration information according to the order of the version numbers from small to large for the network configuration information with the same feature value and network feature type, and then issues the network configuration information to the gateway device in batches, where the issue content may include the network configuration information and the version number of the configuration.

In this embodiment, after receiving the configuration, the cloud gateway proxy (XGWAgent) sequentially parses the configuration content, and for each configuration, the cloud gateway proxy uses the network feature type and the feature value as indexes to find out whether a version number record exists locally, if not, the version number of the current configuration is stored as an initial version number, if so, whether the version number of the current configuration is equal to the local version number plus 1 is judged, if so, the configuration is received so that the local version number is plus 1, and the correctness is returned, otherwise, the error is directly returned.

Optionally, various message formats can be adopted between the SDN controller and the cloud gateway proxy, for example, the SDN controller adopts a message format of serializing the configuration into binary, and when the cloud gateway proxy receives the binary sequence, the SDN controller can deserialize according to a protocol format to obtain configuration content which can be identified by a program, so that the cloud gateway proxy (XGWAgent) can sequentially analyze the configuration content after receiving the configuration.

Optionally, storing the currently effective maximum version number by taking the network feature type and the feature value as a unique index at the local of the cloud gateway proxy end so as to realize that the cloud gateway proxy end uses the network feature type and the feature value as indexes to search whether a version number record exists locally.

In this embodiment, the SDN controller analyzes the result returned by the cloud gateway proxy, obtains the configuration of successful delivery and failure, marks the configuration of successful delivery as completed, and does not process the configuration of failed delivery, waiting for the next retry to send.

Optionally, when the configuration is issued, the configuration is issued sequentially from small to large according to the version number, and when the configuration of a certain version number fails to be issued, the configuration with a version number larger than the version number cannot be successful.

Optionally, the SDN controller maintains a sequentially increasing version number for configurations having the same network feature type and feature value, where the configuration version numbers of different feature values and network feature types are independent of each other and therefore do not affect each other.

In this embodiment, the network feature type and the feature value are added to the network configuration, and the SDN controller maintains an independent sequentially increasing version number for the configuration with different network feature types and feature values, and ensures that the configuration can be issued to the forwarding device through a version number mechanism. When the configuration of a certain characteristic value fails to be issued, the configuration of other characteristic values is not affected, so that the reliability of the network configuration issuing is realized, the technical problem that the reliability of the network configuration information issuing cannot be ensured is solved, and the technical effect that the reliability of the network configuration information issuing can be ensured is realized.
