A method according to an embodiment of the present invention is directed to solving a related virtual network frame in a related art. It is unable to meet the technical problems of the deployment of complex and diverse telecommunication mobile networks.

The technical solutions of the present application are described in detail below through various embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

FIG. 1 is a schematic flowchart diagram of Embodiment 1 of a method for generating a virtual network according to the present application. This embodiment relates to a specific process for implementing virtual network generation. As shown in Figure 1, the method includes:

S101. Generate a virtual network template, where the virtual network template includes a visualization chart composed of a plurality of nodes by connecting lines.

The template generation module generates a virtual network template, and the generated virtual network template may include a connection between an external network node, a routing node, a network node, a load balancing node, a virtual host node, a firewall node, a security group node, and a node. A visual chart of the composition. The external network node is a channel between the internal virtual network and the external physical network, and the host host of the external physical network accesses the device of the internal virtual network through a floating Internet Protocol (IP) assigned to the internal device. The routing node has the function of grouping and forwarding IP packets, and also functions of NAT (Network Address Translation) and VPN (Virtual Private Network). NAT is the mapping of internal and external IP addresses, and external physics. The network host device allocates a floating IP address to the internal virtual device through the NAT protocol. It should be noted that, for security reasons, the external physical network host device first logs in to the VPN server and then accesses the intranet virtual network device. The network node corresponds to the network and subnet resources. The subnet must exist in the network. A network can contain multiple subnets. The subnet contains one or more virtual hosts. The virtual hosts in the subnet can communicate with each other. Through the gateway. The load balancing node needs to be under the subnet. It can transmit TCP (Transmission Control Protocol) protocol, HTTP (HyperText Transfer Protocol) protocol, HTTPS (HyperText Transfer) to two or more servers that have been exposed. The protocol node of the Protocol over Secure Socket Layer protocol performs round_robin, least-connections, and source-ip policy load balancing, and can also support third-party service provider products, such as the a10 load balancing manufacturer. The firewall node and the security group node belong to the transparent node. The firewall node has no outgoing line, and the security group node has neither incoming nor outgoing. The function of the firewall and security group node is to allow or deny the function of the data packet. The firewall is allowed or denied through the router network:router_gateway and sub The data packets of the network can be filtered by the source IP address or the destination IP address. The firewall can introduce third-party service providers, such as the Hillstone Firewall and the Green League. The firewall technology of the third-party vendor can be used to enhance the firewall capability of the virtual network. The security group filters the network packets under the entire tenant, and can filter the packets through protocols or port ranges. Among them, nodes such as external network nodes, network nodes, routing nodes, firewall nodes, load balancing nodes, security group nodes, and virtual host nodes are visual components in the virtual network template, and these nodes can be connected by practice to form a visualization chart. The parameter information in the above node is included in the chart, and the virtual network template may be generated in the resource operation system (Iros), but is not limited thereto.

It should be noted that the virtual network template developer user enters the template editing interface, and according to the above node and node parameter requirements, a virtual network template is generated through the connection between multiple nodes and nodes, and is published on the Iros. Once the network template is released, it cannot be modified. If there is no instance installed, it can only be modified after the release, but it is not limited to this.

S102. Generate a corresponding virtual network according to the virtual network template.

The virtual network generating module creates a corresponding virtual network in a predetermined order according to the visualization chart in the virtual network template. The generating the virtual network may be performed on a service chain template generation system (Adtsc), and Adtsc sends a request to generate a corresponding virtual network to Opencos (secondary development system of OpenStack), and Opencos may call stack-create of heat to opencos. The stack is created, the initial state of the stack is in the creation, and the state of the stack becomes successful after the virtual network is created. If the virtual network creation fails, the state of the stack changes from being created to failing. If the virtual network template contains a green league or a firewall node, a service chain needs to be created on an SDN (Software Defined Network) controller, and the SDN controller exposes a classifier and a portchain. The rest interface is used to create and delete a service chain. After the service chain is created, the data packets that meet the service chain conditions in the subsequent virtual network are filtered, monitored, forwarded, and offloaded.

The method for generating a virtual network according to an embodiment of the present invention generates a virtual network template, where the virtual network template includes a visualization chart composed of a plurality of nodes through a connection, and generates a corresponding virtual according to the virtual network template. The network can generate a virtual network by visualizing the virtual network template of the chart, which can simplify the creation of the virtual network, and can provide various customized virtual network templates to meet the deployment requirements of complex and diverse telecommunication mobile networks.

In an exemplary embodiment, on the basis of the foregoing embodiment, generating a corresponding virtual network according to the virtual network template may include:

The virtual network template generates a corresponding virtual network according to a predetermined sequence. In the process of generating a virtual network, some resources in the virtual network are dependent. For example, the VPNService must wait for the creation of the RouterInterface and the RouterGateway to be created. You must wait for the creation of RouterGateway to be created, etc., but not limited to this.

Among them, a stack is created in the initial stage of generating the virtual network. For example, Opencos calls the stack-create of heat to create a stack on Opencos. Each stack corresponds to a unique encoding. The initial state of the general stack is in the process of creation. The state of the stack becomes successful after the creation of all the nodes of the virtual network template. If a node fails to be created, the state of the stack changes from being created to fail. Opencos will return the code of the stack to Adtsc. Adtsc returns the message to start the creation of the stack to Iros, but is not limited to this.

In an exemplary embodiment, after the creation of the stack according to the virtual network template and the generation of the corresponding virtual network in a predetermined order, the method may further include:

Among them, a stack is created in the initial stage of generating the virtual network. For example, Opencos calls the stack-create of heat to create a stack on Opencos. Each stack corresponds to a unique encoding. The initial state of the general stack is in the process of creation. Until the creation of all the nodes of the virtual network template is completed, the state of the stack becomes successful. If a node fails to be created, the state of the stack changes from being created to fail. Opencos will return the code of the stack to Adtsc, Adtsc. The message that starts to create the stack is returned to Iros, and Adtsc can query the state of the stack every other cycle. The cycle can be configured according to the actual situation. After the state of the query stack is successful or failed, the state of the stack is returned to Iros. The results of creating an instance can be viewed on Iros, but are not limited to this.

By periodically querying the status of the stack to reflect whether the virtual network is successfully created, it can be obtained in time. Know the progress of the virtual network generation.

In an exemplary embodiment, after the corresponding virtual network is generated according to the virtual network template, the method may further include:

Adjust the corresponding virtual network template and regenerate the virtual network according to the predetermined requirements or when it is determined that the parameters of the generated virtual network are incorrect.

Among them, after the virtual network is installed, it can be put into use. If the original virtual network architecture and parameters are found to be incorrect when it is put into use, the installed virtual network can be adjusted with the correct virtual network architecture and parameters. The predetermined requirement (the predetermined requirement is the requirement for adjustment in the virtual network and node parameters, which can be determined according to the actual situation), and the system administrator of Iros can enter the instance management to modify the virtual network architecture (addition, deletion Component node) and modify the component node parameters, Iros sends the modification message to Adtsc, Adtsc updates the template to Opencos to send the request, and queries the state of the update stack on Opencos every other cycle until the status of the stack is successful or failed. Iros, Opencos calls the function of the heat update stack to update the resource, and the state of the stack enters the update state. When the state of all the resources is updated successfully, the state of the stack changes from successful to successful; if a resource update fails, the state of the stack is updated. Becomes a failure. If you need to add, delete, modify, and adjust the service chain of the SDN controller (for example, the secondary traffic is in the service chain), you can enter the service chain management through the system administrator of Iros, and you can enter the tenant. When the service chain is viewed, added, deleted, and modified, the service chain sequence adjustment can also be performed when the template has secondary drainage.

In an exemplary embodiment, on the basis of the foregoing embodiment, before the generating the virtual network template, the foregoing method may further include:

Before the virtual network template is generated and deployed, the virtual network is first planned. The architecture of the virtual network can be planned. For example, the VLAN is decoupled to implement network communication isolation, and the third-party service provider products are introduced into the virtual network. Create a service chain to filter, monitor, forward, and offload data packets that meet the requirements of the service chain, and also set the usage rights through the system administrator user of Iros, which is used by the template developer to control the allocation. Virtual Whether a node in a proposed network template can be used as a development node.

In an exemplary embodiment, on the basis of the foregoing embodiment, planning the architecture of the virtual network may include:

Wherein, by delineating each virtual local area network (VLAN) of the virtual network in advance, the devices in the local area network are logically and not physically divided into one network segment, thereby realizing the virtual working group, and the network administrator will have a physical LAN logic. The ground is divided into different broadcast domains (or virtual LANs, ie VLANs). Each VLAN contains a set of computer workstations with the same requirements, which have the same properties as the physically formed LAN, but because it is logical rather than Physically divided, so each workstation in the same VLAN does not need to be placed in the same physical space, that is, these workstations do not necessarily belong to the same physical LAN segment, and broadcast and unicast traffic inside a VLAN are not forwarded to In other VLANs, it helps control traffic, reduce equipment investment, simplify network management, and improve network security.

When it is determined that a third-party service provider product enters the virtual network, a service chain is created on the software-defined network (SDN) controller, so that the data packets satisfying the service chain condition are filtered, monitored, forwarded, and offloaded, for example, there is a green league or a firewall. The node needs to create a service chain on the SDN controller. The SDN controller exposes the rest interface of the classfier and the portchain to create and delete the service chain. After the service chain is created, the data packets that meet the service chain conditions are used in the subsequent virtual network. Filter, monitor, forward, and offload.

In an exemplary embodiment, on the basis of the foregoing embodiment, the setting the usage rights of the virtual network may include:

The seven nodes on the virtual network template are edited by adding, deleting, and modifying, and the seven nodes include: an external network node, a network node, a routing node, a firewall node, a load balancing node, a security group node, and a virtual host node. Fill in the parameters in these nodes, and set the parameters of each node in the virtual network to control the usage rights of the nodes through the authority control allocation, so as to further improve the security of the network.

Secondary development system (for example, SDN system).

FIG. 3 is a schematic diagram of template generation of a method for generating a virtual network according to Embodiment 2 of the present application. As shown in Figure 3, before the virtual network is deployed, you must first plan the network, plan the network architecture, demarcate the VLAN to implement network communication isolation, introduce third-party service provider products into the virtual network, and create a service chain on the SDN controller. Filter, monitor, forward, and offload packets that meet the conditions of the service chain. After the basic network architecture is determined, the template developer interface from Iros enters the template editing interface, and 7 nodes (external network nodes, network nodes, routing nodes, firewall nodes, load balancing nodes, security groups) are edited by adding, deleting, and modifying. Node, virtual host node), fill in the parameters in the node, and save the template, thus generating a virtual network template, in which the system administrator user of Iros can assign the template development node usage authority to the template developer through the permission control, otherwise the template development You cannot use a template to develop a node.

FIG. 4 is a schematic diagram of virtual network generation of a method for generating a virtual network according to Embodiment 2 of the present application. As shown in Figure 4, after the virtual network template is generated, the template is published on the Iros. Once the template is published, it cannot be modified (if the instance is not installed, it can be modified after the release is released). After the template is released, enter the system administrator user to install the template. Iros sends a request to install the template to Adtsc. Adtsc sends a request to Opencos to install the template. Opencos calls heat's stack-create to create a stack on Opencos. The state of the stack is in the process of creation. The state of the stack becomes successful after the creation of all the components of the template. If a component fails to be created, The state of the stack changes from being created to failing. Opencos returns the stack ID to Adtsc, which returns the message to start the stack to Iros, and then Adtsc queries the stack every other cycle (configurable). The state of the stack is returned to Iros until the state of the query stack is successful or failed. The results of creating an instance can be viewed on Iros. If the template contains a Green League or firewall node, you need to create a service chain on the SDN controller. The SDN controller exposes the rest interface of the classfier and the portchain to create and delete the service chain. After the service chain is created, the data packets that meet the service chain conditions in the subsequent virtual network are filtered, monitored, forwarded, and offloaded. In the process of installing a virtual network, some resources of the virtual network are dependent. For example, the VPNService must wait for the creation of the RouterInterface and RouterGateway to be created. The Firewall must wait for the creation of the RouterGateway to be created.

As shown in Figure 5 and Figure 6, the service network of the virtual network and SDN controller can be put into use after it is successfully created. If the original virtual network architecture or parameters are found to be incorrect, you can use the system administrator of Iros. Enter the instance management to modify the virtual network architecture (add, delete component nodes) and modify the component node parameters, Iros send the modification message to Adtsc, Adtsc update template sends a request to Opencos, and query Opencos every other cycle (configurable) Update the state of the stack until the state of the stack is successful or failed before returning the result to iros. Opencos calls the function of the heat update stack to update the resource. The state of the stack enters the update state. When all resources are successfully updated, the state of the stack changes from successful to successful. If a resource update fails, the state of the stack changes from update to failure. The modification of the virtual network also includes the addition, deletion, modification, and sequence adjustment of the service chain (in the case of secondary traffic in the service chain). The system administrator of the Iros enters the service chain management, and the service chain under the tenant can be viewed. Add, delete, and modify operations. When the template has secondary drainage, the business chain order adjustment can be performed.
