[0002] With the rapid development of information technology, the Internet has penetrated into all aspects of work and life, and the demand for IP addresses is also growing. In order to meet the needs of upgrading and transforming VLAN (Virtual Local Area Network) networks from IPv4 (Internet Protocol version 4) to IPv6 (Internet Protocol version 6) in cloud computing platforms, dual-stack technology is an effective transition technology. Dual-stack technology refers to running two sets of IPv4 and IPv6 protocol stacks on the same device at the same time, so that data packets of two different protocols, IPv4 and IPv6, can be processed at the same time to achieve intercommunication between IPv4 and IPv6 networks. However, the current implementation of dual-stack technology requires upgrading each IPv4 node, which is costly and does not solve the shortage of IPv4 addresses. It is highly dependent on a single physical hardware device, and the system flexibility and compatibility are poor, resulting in the inability of customers' virtual machine services to maintain efficient and stable communication capabilities during the upgrade process.

[0003] In summary, how to promote the smooth upgrade of VLAN network from IPv4 to IPv6 to ensure business continuity is an urgent problem to be solved. Summary of the invention

[0017] Verify whether the target virtual local area network exists on the target cloud computing platform based on the local area network ID of the target virtual local area network using the target dual-stack application programming interface;

[0018] If the target virtual local area network does not exist on the target cloud computing platform, it is prohibited to create a first cloud host and an elastic network card under the target virtual local area network.

[0019] Optionally, the virtual local area network cloud host dual stack communication method further includes:

[0020] If an exception occurs during the dual-stack communication process, the first cloud host and the elastic network card are restored using the target information stored in the target database to continue the dual-stack communication process.

[0021] Optionally, the preset dual-stack communication condition includes that a second target connection between the second cloud host and the target subnet is normal, and a third target connection between the second cloud host and the first cloud host is normal.

[0022] In a second aspect, the present application discloses a virtual local area network cloud host dual stack communication device, comprising:

[0023] A target subnet creation module is used to create a target virtual local area network on a target cloud computing platform by using a target dual-stack application programming interface and a dual-stack northbound interface through a dual-stack management and control center, and to create a target subnet in the target virtual local area network; the target subnet includes a first target subnet and a second target subnet, and the first target subnet and the second target subnet correspond to different Internet protocols;

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] At present, the implementation of dual-stack technology requires upgrading each IPv4 node, which is costly and does not solve the shortage of IPv4 addresses. It is highly dependent on a single physical hardware device, and the system flexibility and compatibility are poor, resulting in the inability of customers' virtual machine services to maintain efficient and stable communication capabilities during the upgrade process. In order to solve the above technical problems, the present application discloses a virtual local area network cloud host dual-stack communication method, which can promote the smooth upgrade of VLAN networks from IPv4 to IPv6 to ensure business continuity.

[0041] See also Figure 1 As shown, an embodiment of the present invention discloses a virtual local area network cloud host dual stack communication method, including:

[0042] Step S11: Create a target virtual local area network on a target cloud computing platform through a dual-stack management and control center using a target dual-stack application programming interface and a dual-stack northbound interface, and create a target subnet in the target virtual local area network; the target subnet includes a first target subnet and a second target subnet, and the first target subnet and the second target subnet have different Internet protocols corresponding to them.

[0043] In this embodiment, the implementation architecture of dual stack communication is as follows: Figure 2As shown in the figure, it mainly includes dual-stack northbound interface, dual-stack management control center, target database, dual-stack switch and Neutron dual-stack API (Application Programming Interface), etc. It is not dependent on the limitations of any single physical hardware device, thus enhancing the flexibility and compatibility of the system. Figure 3 As shown. The dual-stack northbound interface is mainly used to provide the upper-layer cloud management platform (including the target cloud computing platform) or third-party systems and third-party platforms with dual-stack interfaces. These interfaces include VLAN network query list, view details, and modify, subnet query list, view details, and modify, cloud host creation, deletion, modification, query list, and view details, network card creation, deletion, modification, query list, and view details. It is understandable that the creation and deletion of VLAN networks requires operation and maintenance personnel (i.e. Figure 3 The developer in the cloud management platform (in the developer terminal) operates through the developer terminal, so it is not allowed to create and delete on the product side. The VLAN list interface displays the network ID, name, network segment and other information, and the subnet list interface displays the subnet ID, name, IPv4 network segment, IPv6 network segment and other information, ensuring the accuracy and efficiency of the operation, and avoiding the security risks that may be introduced through the product interface, ensuring the network security of the cloud platform. The dual stack management control center is mainly responsible for the core business logic processing of the dual stack. When the user creates a cloud host and turns on the dual stack through the cloud management platform interface or API interface, the dual stack northbound interface will trigger the dual stack management control center to perform specific dual stack operations, such as creation, modification, and deletion. The dual stack management control center records the user's cloud host and dual stack network card information into the target database for persistence. The target dual stack application programming interface can be the Neutron dual stack API, which is responsible for the comprehensive management of the VLAN network life cycle (including creation, deletion, modification, query), as well as the corresponding operations of the cloud host and network card. Therefore, the creation of the VLAN network can be performed through the console interface or by using the OpenStack command line tool.

[0044] In this embodiment, the target cloud computing platform may be a cloud computing management platform based on OpenStack, and the VLAN number of the created target virtual local area network may be 2000. Figure 3VLAN2000 in the target virtual LAN is created; then create two target subnets under the VLAN network, where the IPv4 subnet segment can be 192.168.1.0 / 24, and the IPv6 subnet segment can be 2402:: / 64. After the target virtual LAN is created on the target cloud computing platform through the dual-stack management control center using the target dual-stack application programming interface and the dual-stack northbound interface, the target subnet can be created in the target virtual LAN; the target subnet includes a first target subnet and a second target subnet, and the first target subnet and the second target subnet have different Internet protocols. Specifically, the first target subnet is an IPv4 subnet (that is, Figure 3 subnet-1 in the second target subnet is the IPv6 subnet (that is, Figure 3 It is understandable that the number of the first target subnets is not less than one, and the number of the second target subnets is not less than one.

[0045] In this embodiment, when creating an IPv6 subnet, special attention should be paid to the settings of the two key attributes ipv6-ra-mode and ipv6-address-mode, that is, the specific process of creating a target subnet in the target virtual LAN may include: setting the target attribute of the second target subnet to the target mode to create the target subnet in the target virtual LAN. In this embodiment, these two key attributes (i.e., target attributes) can be set to dhcpv6-stateful to ensure the correct allocation of IPv6 addresses. Among them, ipv6_ra_mode determines how the router in the subnet notifies the client of its existence and configuration information through ICMPv6 messages (Router Advertisement of type 134, referred to as RA). RA is not only the key to network connectivity, but also carries the important notification function of network parameters. ipv6_address_mode determines how the client obtains the IPv6 address. It directly affects the mechanism and efficiency of address allocation and is the core link in IPv6 network configuration.

[0046] In this embodiment, if the target attribute is configured as dhcpv6-stateful, that is, stateful DHCPv6 (a network protocol used to configure the IP address, IP prefix and / or other configurations required by IPv6 hosts working on an IPv6 network) mode, in this mode, the IPv6 address and other network parameters (such as DNS server address) are dynamically allocated through the DHCPv6 server. It provides higher configuration flexibility and management capabilities, but requires additional DHCPv6 service support. It is understandable that the target attribute can also be configured as SLAAC (Stateless Address AutoConfiguration, stateless automatic configuration mode) or dhcpv6-stateless (that is, stateless DHCPv6 mode). In SLAAC mode, the client parses the prefix information in RA and combines its own interface identifier (such as EUI-64 or randomly generated) to independently complete the configuration of IPv6 address. This method does not rely on additional server resources and is efficient and flexible. In dhcpv6-stateless mode, the generation of IPv6 address still follows the SLAAC principle, but only other network configuration information (such as DNS (Domain Name System) resolver) is obtained through DHCPv6 service. This mode combines the efficiency of SLAAC and the flexibility of DHCPv6, and is suitable for scenarios that require additional configuration but automatic address allocation. By properly configuring ipv6-ra-mode and ipv6-address-mode, the OpenStack platform can flexibly and efficiently support IPv6 dual-stack networks to meet the diverse network application requirements.

[0047] Step S12: configure the target virtual local area network, the first target subnet and the second target subnet on the dual-stack switch, and create a first cloud host and an elastic network card under the target virtual local area network.

[0048] In this embodiment, the dual stack switch is mainly responsible for the configuration of the switch, including the VLAN number, the ipv4 subnet segment and mask, and the ipv6 subnet segment and mask. Therefore, the target virtual LAN, the first target subnet and the second target subnet are configured on the dual stack switch, which may specifically include: allocating a target port for the target virtual LAN on the dual stack switch, and allocating a first target address and a first subnet mask for the first target subnet, and allocating a second target address and a second subnet mask for the second target subnet; activating the target port corresponding to the target virtual LAN through a target command. For example, create a VLAN named VLAN2000, and assign the FastEthernet0 / 1 port to VLAN 2000, then configure an IPv4 address 192.168.1.1 / 24 for VLAN 2000, and a subnet mask of 24 bits, and configure an IPv6 address 2402::1 / 64 for VLAN 2000, and a subnet mask of 64 bits; finally, activate the VLAN interface through the no shutdown command. It is understandable that the specific commands and configurations may vary depending on the switch and operating system of different manufacturers (such as Cisco IOS, H3C, Foundry, etc.). The above examples are applicable to Cisco devices. Devices of other manufacturers may require different commands or configuration methods.

[0049] In this embodiment, Figure 4As shown, before creating the first cloud host and elastic network card under the target virtual LAN, it is also necessary to verify whether the target virtual LAN exists on the target cloud computing platform based on the LAN ID of the target virtual LAN through the dual stack management control center using the target dual stack application programming interface, that is, whether the VLAN is available; if the target virtual LAN does not exist on the target cloud computing platform, it is prohibited to create the first cloud host and elastic network card under the target virtual LAN, and a prompt message indicating that the network information does not exist is returned. When creating a cloud host, it is necessary to select a network and a subnet. If the target virtual LAN exists on the target cloud computing platform, the VLAN can be selected on the target cloud computing platform. The network number is 2000, and there are two subnets under the corresponding VLAN network. The IPv4 subnet segment is 192.168.1.0 / 24, and the IPv6 subnet segment is 2402:: / 64. Select the IPv4 subnet and check the button to enable IPv6 on the interface. You can see the IPv6 subnet segment under the current VLAN. At this time, you can check the IPv6 subnet and select the IPv4 subnet and IPv6 subnet to create the first cloud host. Since the interface of the elastic network card will be called when the dual stack is enabled when creating the cloud host, the dual stack northbound interface is called to create the elastic network card and encapsulate the parameters of the port creation. The IPv4 subnet can specify the IP address, and the IPv6 subnet's IP address is automatically assigned and cannot be specified. It is understandable that once the VLAN network dual stack is enabled, it is not allowed to be turned off. If the cloud host only needs to meet the IPv4 protocol stack, you can uncheck the button to enable IPv6 on the IPv4 subnet interface in the above steps. In this way, only the address of the IPv4 subnet will be assigned when creating the elastic network card, and the created cloud host will only have an IPv4 address. This embodiment not only simplifies the operation process and ensures the convenience of operation, but also allows users to freely configure the IPv4 and IPv6 network segments of the VLAN subnet according to the specific needs of the cloud center, greatly improving the flexibility and adaptability of network deployment and optimizing the adaptability and scalability of the network architecture. After IPv6 is enabled on the VLAN network, information exchange with IPv4 or IPv6 nodes is achieved, ensuring the normal communication of customer virtual machine services.

[0050] Step S13: store the target information of the first cloud host and the elastic network card in a target database, configure a target subnet address for the first cloud host, and determine whether the first target connection between the first cloud host and the target subnet is normal.

[0051] In this embodiment, the target information of the first cloud host and the elastic network card, such as network, subnet, eni (Elastic Network Interfaces, elastic network card), ecs (Elastic Compute Service, a simple, efficient, safe and reliable computing service with elastically scalable processing power), etc., is written into the target database, and then the IP address of the IPv6 subnet obtained in the above process is configured to the first cloud host. Taking the image type of Ubuntu 18 and above as an example, when configuring the target subnet address for the first cloud host, first enter the cd / etc / netplan directory, then configure the IP address, mask and gateway of the IPv6 subnet, and finally execute the netplan apply command to make the configuration effective. After the configuration is completed, in order to determine whether the first target connection between the first cloud host and the target subnet is normal, you can log in to the first cloud host and determine whether the first cloud host can ping the IPv4 gateway and the IPv6 gateway. If both can be pinged, it means that the first target connection is normal. Among them, there are two tables involving elastic network card information in the target database: the elastic network card table (port) and the elastic network card association table (port_reference_ip). The elastic network card table stores the network card ID, name, IPv4 address, MAC address, network ID, subnet ID, etc. The elastic network card association table stores the network card ID, IPv6 address, creation time, etc.

[0052] Step S14: If the first target connection between the first cloud host and the target subnet is normal, create a second cloud host under the target virtual local area network so that the second cloud host can perform dual-stack communication with the first cloud host when a preset dual-stack communication condition is met.

[0053] In this embodiment, if the first target connection is normal, a second cloud host can be created under the target virtual local area network, and it is determined whether the second cloud host meets the preset dual-stack communication conditions, that is, the second target connection between the second cloud host and the target subnet is normal, and the third target connection between the second cloud host and the first cloud host is normal, that is, the second cloud host can ping the intranet address of the first cloud host. If the second cloud host meets the preset dual-stack communication conditions, the second cloud host can perform dual-stack communication with the first cloud host. It is understandable that there is no less than one second cloud host, and a corresponding number of second cloud hosts can be created according to user needs to perform dual-stack communication with the first cloud host.

[0054] In addition, the target database is mainly responsible for the persistence of cloud host and dual-stack network card data. If an exception occurs during the dual-stack communication process, the target information stored in the target database can be used to restore the first cloud host and elastic network card to continue the dual-stack communication process, thereby ensuring the availability of the user's dual-stack business.

[0055] It can be seen that this application uses the target dual-stack application programming interface and the dual-stack northbound interface to create a target virtual LAN on the target cloud computing platform to create a target subnet through the dual-stack management and control center, ensuring that there are both IPv6 subnets and IPv4 subnets under the target virtual LAN; the dual-stack northbound interface is mainly used to provide an interface for enabling dual stacks to the upper-level platform or third-party system or platform. After the configuration of the VLAN network and each target subnet is completed, the interface can be used to enable the IPv6 dual-stack option corresponding to the IPv4 subnet when creating a cloud host. The dual-stack northbound interface will trigger the dual-stack management and control center to perform specific dual-stack operations. When the first target connection is normal and the second cloud host meets the preset dual-stack communication conditions, the first cloud host and the second cloud host can perform dual-stack communication, thereby realizing flexible and efficient planning of VLAN network segments, which not only simplifies the operation process, but also ensures the speed of operation, so that the target cloud computing platform can flexibly and efficiently support IPv6 dual-stack networks to meet diverse network application needs.
