Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element. Referring to fig. 1, fig. 1 is a schematic view of an implementation flow of a virtual network creating method according to an embodiment of the present invention, as shown in fig. 1, the method mainly includes the following steps:

step 101, creating a virtual cloud computing platform in a data center cluster environment.

In some embodiments, the data center cluster environment includes at least 2 computing devices, and the computing devices are connected by a network to form the data center cluster environment, the data center cluster including computing resources, storage resources, and network resources.

Creating a virtual cloud computing platform in the data center cluster environment comprises virtualizing each computing device of the data center cluster into at least 2 nodes, and connecting each node through a network to form the virtual cloud computing platform.

For example, the data center cluster environment includes three computers, each of which is connected to each other through a switch, a router, and a firewall to form the data center cluster environment, and a central processing unit of each computer supports a virtualization function. And virtualizing each computer into nodes by a virtualization technology, and connecting the nodes to form a virtual cloud computing platform.

Computing resources, storage resources and network resources of a data center cluster environment are abstracted into a computing resource pool, a storage resource pool and a network resource pool by creating a virtual cloud computing platform. When computing resources, storage resources and network resources are allocated to create virtual nodes in a virtual network, the computing resources, the storage resources and the network resources can be directly allocated from a computing resource pool, a storage resource pool and a network resource pool through the computing cloud platform, without concern about which computing devices in a data center cluster environment the computing resources and the storage resources are specifically distributed in and how the network address information is allocated.

And 102, storing routing service software in the virtual cloud computing platform.

In some embodiments, the routing service software is software that can implement the functionality of a router.

The routing service software is stored in the virtual cloud computing platform, so that the virtual cloud computing platform has the function of creating the virtual router node.

Step 103, creating a virtual node and a virtual router node in the virtual cloud computing platform based on the configuration file, and mounting the routing service software into the virtual router node.

In some embodiments, the configuration file includes node parameters based on which virtual nodes and virtual router nodes are created.

For example, the node parameters include the number of virtual nodes and virtual router nodes in the virtual network, and each virtual node and each virtual router node may invoke computing resources and storage resources of the virtual cloud computing platform.

The method comprises the steps that virtual nodes and virtual router nodes in corresponding quantities are created in a virtual cloud computing platform based on the quantities of the virtual nodes and the virtual router nodes in a virtual network, computing resources and storage resources of the virtual cloud computing platform can be called based on the virtual nodes and the virtual router nodes, and the computing resources and the storage resources of the virtual cloud computing platform are respectively configured to the virtual nodes and the virtual router nodes.

And each virtual node and each virtual router node call the computing resources and the storage resources of the virtual cloud computing platform to execute computing tasks. The routing service software is mounted in the virtual router node, and the virtual router node can realize the function of the router by running the routing service software.

And 104, connecting the virtual router nodes in the virtual cloud computing platform with the virtual nodes based on the configuration file to form a virtual network comprising the virtual nodes and the virtual router nodes.

In some embodiments, the configuration file further includes network parameters, and the virtual router nodes in the virtual cloud computing platform are connected with the virtual nodes based on the network parameters of the virtual network to form a virtual network including the virtual nodes and the virtual router nodes.

For example, the network parameters include the network address of each virtual node and the network address of each virtual router node connection. And based on the network address of the virtual node, distributing the network address to each corresponding virtual node, and based on the network address connected with the virtual router, connecting the virtual router node and the corresponding virtual node to form a virtual network comprising the virtual node and the virtual router node, wherein the topological structure of the virtual network corresponds to the network parameter.

Because the virtual router nodes are introduced into the virtual network, a three-layer virtual network comprising the virtual nodes, the switch and the virtual router nodes can be established, and the established virtual network can have a differential network structure, so that the diversity requirement of network simulation is met.

According to the virtual network creating method provided by the embodiment of the invention, the virtual nodes and the virtual router nodes are created in the virtual cloud computing platform based on the configuration file, the routing service software is mounted in the virtual router nodes, and the virtual router nodes in the virtual cloud computing platform are connected with the virtual nodes based on the configuration file to form the virtual network comprising the virtual nodes and the virtual router nodes.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating an implementation of a virtual network creating method according to an embodiment of the present invention, as shown in fig. 2, the method mainly includes the following steps:

In some embodiments, the computing nodes invoke computing resources and storage resources of the data center cluster environment to perform computing tasks, the control nodes allocate the computing resources and storage resources of the data center cluster environment, and the network nodes allocate network resources of the data center cluster environment.

Step 202, connecting the control node and the computing node through a management network, and connecting the network node and the computing node through the management network to form a virtual cloud computing platform comprising the computing node, the control node and the network node.

In some embodiments, the management network is used for internal communication between nodes in the virtual cloud computing platform.

The data transmission between the control node and the computing node is realized by connecting the control node and the computing node through the management network, and the data transmission between the management network and the computing node is realized by connecting the network node and the computing node through the management network.

And step 203, storing the routing service software in the virtual cloud computing platform.

The execution process of step 203 is completely the same as that of step 102, and therefore is not described herein again.

And step 204, creating a virtual node in the computing node of the virtual cloud computing platform through the control node of the virtual cloud computing platform based on the virtual node information in the configuration file.

In some embodiments, the configuration file includes virtual node information.

Based on the virtual node information, a virtual node is created in a computing node of the virtual cloud computing platform through a control node of the virtual cloud computing platform, the virtual node calls computing resources of the computing node to execute computing tasks, and the size of the computing resources which can be called by the virtual node corresponds to the virtual node information of the virtual node.

For example, the virtual node information includes: a virtual node A having 3 computing processes; virtual node B, with 2 computation processes.

And creating a virtual node A and a virtual node B in the computing nodes of the virtual cloud computing platform through the control nodes of the virtual cloud computing platform based on the virtual node information. The virtual node A can call 3 computing processes of the computing node to execute computing tasks, and the virtual node B can call 2 computing processes of the computing node to execute computing tasks.

Step 205, based on the virtual router node information in the configuration file, creating a virtual router node in a computing node of the virtual cloud computing platform through a control node of the virtual cloud computing platform, and mounting the routing service software into the virtual router node.

In some embodiments, the configuration file includes virtual router node information.

Based on the virtual router node information, a virtual router node is created in a computing node of the virtual cloud computing platform through a control node of the virtual cloud computing platform, and routing service software is mounted into the virtual router node.

The virtual router node calls the computing resource of the computing node to run the routing service software to realize the function of the router, and the size of the computing resource which can be called by the virtual router node corresponds to the virtual router node information of the virtual router node.

For example, the virtual router node information includes: virtual router node a, has 2 computing processes.

And based on the virtual router node information, creating a virtual router node A in the computing nodes of the virtual cloud computing platform, and mounting the routing service software into the virtual router node A. The virtual router node a can invoke 2 processes of the compute node to run the routing service software, implementing the function of the virtual router.

And step 206, allocating the network address in the network address range corresponding to the virtual subnet name to the virtual node through the network node of the virtual cloud computing platform based on the virtual subnet name accessed by the virtual node in the configuration file.

In some embodiments, the virtual network includes at least one virtual subnet, at least one virtual node accesses to one virtual subnet, and the configuration file includes a virtual subnet name accessed by the virtual node and a network address range corresponding to the virtual subnet name.

And based on the virtual subnet names accessed by the virtual nodes, allocating the network addresses in the network address range corresponding to the virtual subnet to the virtual nodes through the network nodes of the virtual cloud computing platform.

For example, the virtual network includes a virtual subnet 1 and a virtual subnet 2, the network address range of the virtual subnet 1 is 192.168.1.1 to 192.168.1.24, and the network address range of the virtual subnet 2 is 192.168.2.1 to 192.168.2.24.

The virtual node a is accessed into the virtual subnet 1 and the virtual node B is accessed into the virtual subnet 2. One network address in the network address range 192.168.1.1 to 192.168.1.24 is assigned to virtual node a and one network address in the network address range 192.168.2.1 to 192.168.2.24 is assigned to virtual node B. For example, virtual node a is assigned network address 192.168.1.1 and virtual node B is assigned network address 192.168.2.3.

Step 207, connecting the virtual router node with the virtual node through the network node of the virtual cloud computing platform based on the name of the subnet connected with the virtual router node in the configuration file to form a virtual network comprising the virtual node and the virtual router node.

In some embodiments, the configuration file includes the sub-network names to which the virtual router nodes are connected.

And based on the subnet name connected with the virtual router node, connecting the virtual router node with the virtual node in the subnet corresponding to the subnet name through the network node of the virtual cloud computing platform.

Based on the name of the sub-network connected with the virtual router node, network addresses of network cards of the virtual router node A and the virtual router node B are configured through a network node of the virtual cloud computing platform, so that the virtual router node A is connected with the virtual node A and the virtual node B, the virtual router node A is connected with the virtual node A and the virtual node C, the virtual router node B is connected with the virtual node B and the virtual node D, and the virtual router node B is connected with the virtual node C and the virtual node D, so that a virtual network comprising the virtual node A, the virtual node B, the virtual node C, the virtual node D, the virtual router node A and the virtual router node B is formed.

For example, the routing table of the virtual router node is queried through the incrementally configured API or static routing management and packet filtering management are performed on the virtual router node.

In some embodiments, after a virtual router node is introduced into an OpenStack platform, the virtual router node may be started in a manner of starting the virtual node, with a difference that the virtual router node needs to mount a plurality of network interfaces.

And step 14, starting the automatic virtual network deployment system.

In some embodiments, the virtual network automatic deployment system authenticates the user identity, and automatically analyzes the virtual network topology configuration file after authentication to obtain parameters required for building the virtual network.

For example, automatically parsing the network topology configuration file shown in fig. 12 includes initializing a data structure of the network topology configuration file, and constructing a root node through a topo (root) tag, where a specific procedure may be, for example:

from xml.etree import ElementTree as ET

tree＝ET.parse(“./topo.xml”)

root＝tree.getroot(tree)

after the root node is constructed, parameters required for constructing the virtual network are obtained from the virtual network topology file through the query tag, for example, virtual router node information and virtual node information are obtained through a root.

Referring to fig. 14, fig. 14 is a topology structure diagram of a virtual network, as shown in fig. 14, the virtual network includes 6 virtual subnets, a virtual node H1 is connected to a virtual subnet net1, a virtual node H2 is connected to a virtual subnet net2, and a virtual router node R1 is connected to a virtual node H1 and a virtual node H2.

And step 15, testing the virtual network.

In some embodiments, each virtual router node is logged in through an incrementally configured API, a routing table of each virtual router node is checked, each virtual node is logged in, and a network connectivity condition of the virtual node is tested.

For example, the virtual router node is registered through the API configured in increments, please refer to fig. 15, fig. 15 is a routing table of the virtual router node, as shown in fig. 15, the routing table is automatically formed in the virtual router node.

Then, the virtual nodes are logged in, and the communication between each virtual node and other virtual nodes or virtual router nodes is tested through a ping command, please refer to fig. 16, where fig. 16 is a schematic diagram of a test result of a virtual node, as shown in fig. 16, the virtual node seamlessly communicates with another virtual node in a network, and is connected with another virtual node through a three-hop virtual router.

In some embodiments, the virtual network creating method further includes logging in each virtual router node through an incrementally configured API, and incrementally configuring the virtual router node, referring to fig. 17, fig. 17 is a schematic diagram of a part of a program for incrementally configuring the virtual router node, as shown in fig. 17, incrementally configuring the virtual router node through the incrementally configured API includes querying a router table of the virtual router node, and adding a static routing path to the routing table.

In some embodiments, the virtual network creating method further includes, when the user needs to change the network scenario, modifying the virtual network topology configuration file, and performing the foregoing step 14 based on the modified virtual network topology configuration file to reconstruct the virtual network.

In some embodiments, the reconfiguration of the virtual network includes creating a network and deleting a network, and the method of creating a network may be, for example, by commanding: create _ network (body) calls a neutron _ client (object entity of network virtualization, meaning of neutron _ client in the following is the same) service module of the OpenStack platform to operate network resources of the OpenStack platform to create a virtual network, wherein the body is a specific network to be created. The method for deleting the network may be, for example, invoking the neutron _ client of the OpenStack platform by a command to operate the network resource of the OpenStack platform to delete the specified virtual network, where the body is a specific network that needs to be deleted.

For example, a virtual subnet needs to be created in a virtual network, and network information of the virtual subnet needs to be created is obtained after parsing, where the network information of the virtual subnet includes: the name of the virtual subnet and the network address range of the virtual subnet. The name of the virtual subnet is net1, and the network address range of the virtual subnet is 192.168.1.0 to 192.168.1.24.

After the network information of the virtual subnet is transmitted to the OpenStack platform, the validity of the virtual subnet is checked first, for example, whether the network address range of the virtual subnet is valid or not and whether the subnet conflicts with the existing virtual network or not is checked. And after legal check is passed, starting the multiple processes to send a network creation request to the OpenStack platform, and creating the virtual subnet by utilizing the neutron _ client multiple processes of the OpenStack platform.

In some embodiments, reconstructing the virtual network further includes creating and deleting virtual nodes, and the method for creating the virtual nodes may be, for example, creating virtual nodes by instructing nova _ client.servers.create (body) to invoke nova _ client of the OpenStack platform (calculating a virtualized object entity, and meaning of the nova _ client in the following description is the same), where the body is specific configuration information of the virtual nodes that need to be created. The method for deleting the virtual node may be, for example, invoking the nova _ client of the OpenStack platform by commanding the nova _ client.servers.delete (body) to delete the virtual node, where the body is specific configuration information of the virtual node to be deleted.

For example, a virtual node needs to be created in a virtual network, where the configuration of the virtual node includes a node name Router1, a mirror name Router _3nic _ configfile _ v2, a configuration size m1.medium, a mount network net1 and net2, and a deployment domain computer1 node, and first, the virtual node is determined to be a virtual Router node according to the mirror name, and then, whether the virtual Router node is a fully virtualized virtual Router node or a lightweight virtual node is determined according to the comparison between the mirror name and a mirror image in a mirror image repository of an OpenStack platform, and then, a creation command of the virtual node is sent to the OpenStack platform in batch, so that the OpenStack platform calls a nova _ client or a docker container, and the virtual node is created in a multi-process manner.

And 24, judging whether the authentication is passed or not.

In some embodiments, the keystone service module of the OpenStack platform determines whether the operation of the deployment system is authenticated according to whether user authentication information exists in the network description file.

For example, the keystone service module performs identity authentication according to identity information in the OpenStack platform, including a user name, a password, and the like. Only through the authenticated user, the calculation virtualization object entity nova _ client and the network virtualization object entity neutron _ client can be obtained, so that the nova _ client is called to operate the calculation resource, and the neutron _ client is called to operate the virtual network resource.

If the operation of the deployment system is authenticated, step 25 is performed.

If the operation of the deployment system is not authenticated, step 211 is executed.

And step 25, topology analysis.

In some embodiments, the configuration information in the network description file is parsed by the deployment system.

And step 26, acquiring the virtual network information.
