[0002] With the rapid development of information technology, the internet has permeated every aspect of work and life, and the demand for IP addresses is growing. Dual-stack technology is an effective transitional technology for the migration of VLANs (Virtual Local Area Networks) from IPv4 (Internet Protocol version 4) to IPv6 (Internet Protocol version 6) in cloud computing platforms. Dual-stack technology involves running both IPv4 and IPv6 protocol stacks on the same device, enabling simultaneous processing of packets from both protocols and enabling interoperability between IPv4 and IPv6 networks. However, current implementation of dual-stack technology requires upgrading every IPv4 node, resulting in significant costs. It does not address the shortage of IPv4 addresses, is highly dependent on a single physical hardware device, and suffers from poor system flexibility and compatibility. This results in customers' virtual machine services being unable to maintain efficient and stable communication during the upgrade process.

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

[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 interface 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, configured to create a target virtual local area network on a target cloud computing platform 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 subnets include a first target subnet and a second target subnet, and the first target subnet and the second target subnet correspond to different Internet protocols;

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 the 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.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0040] Currently, the implementation of dual-stack technology requires upgrading every IPv4 node, which is costly and does not address the shortage of IPv4 addresses. Furthermore, it is highly dependent on a single physical hardware device, resulting in poor system flexibility and compatibility. This results in customers' virtual machine services being unable to maintain efficient and stable communication capabilities during the upgrade process. To address the above technical issues, this application discloses a dual-stack communication method for virtual local area network (VLAN) cloud hosts, which can facilitate the smooth upgrade of VLAN networks from IPv4 to IPv6, thereby ensuring service 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 the target cloud computing platform through the dual-stack management and control center using the target dual-stack application programming interface and the 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 Internet protocols corresponding to the first target subnet and the second target subnet are different.

[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) and other components. 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 querying the list, viewing details, and modifying VLAN networks; querying the list, viewing details, and modifying subnets; creating, deleting, modifying, querying the list, and viewing details of cloud hosts; and creating, deleting, modifying, querying the list, and viewing details of network cards. It is understandable that since the creation and deletion of VLAN networks requires operation and maintenance personnel (i.e. Figure 3 Developers in the cloud management platform (likely a developer) operate through the developer terminal, so creation and deletion on the product side is not allowed. The VLAN list interface displays information such as network ID, name, and network segment, while the subnet list interface displays information such as subnet ID, name, IPv4 network segment, and IPv6 network segment. This ensures accurate and efficient operation, avoids security risks that may be introduced through product interfaces, and ensures the network security of the cloud platform. The Dual Stack Management and Control Center is primarily responsible for processing the core business logic of the Dual Stack. When a user creates a cloud host and enables Dual Stack through the cloud management platform interface or API, the Dual Stack northbound interface triggers the Dual Stack Management and Control Center to perform specific Dual Stack operations, such as creation, modification, and deletion. The Dual Stack Management and Control Center records the user's cloud host and dual stack network interface information in a target database for persistence. The target Dual Stack Application Programming Interface (API), such as the Neutron Dual Stack API, is responsible for comprehensive management of the VLAN network lifecycle (including creation, deletion, modification, and query), as well as related operations on cloud hosts and network interfaces. Therefore, VLAN network creation can be performed through the console interface or using OpenStack command-line tools.

[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 creating the target virtual LAN 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, you can create a target subnet in the target virtual LAN; the target subnet includes the first target subnet and the second target subnet, and the Internet protocols corresponding to the first target subnet and the second target subnet are different. 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 first target subnets is not less than one, and the number of 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. Specifically, the specific process of creating a target subnet in a target virtual local area network (VLAN) may include setting the target attribute of the second target subnet to target-mode to create the target subnet in the target VLAN. In this embodiment, these two key attributes (i.e., target attributes) can be set to dhcpv6-stateful to ensure correct IPv6 address allocation. The ipv6_ra_mode attribute determines how routers within the subnet notify clients of their existence and configuration information via ICMPv6 messages (Type 134 Router Advertisement, or RA). RAs are not only critical for network connectivity but also carry the important function of notifying network parameters. The ipv6_address_mode attribute determines how clients obtain IPv6 addresses. It directly impacts the mechanism and efficiency of address allocation and is a core component of IPv6 network configuration.

[0046] In this embodiment, if the target attribute is configured as dhcpv6-stateful, which is stateful DHCPv6 (a network protocol used to configure the IP address, IP prefix, and / or other configuration required by IPv6 hosts operating on an IPv6 network), in this mode, IPv6 addresses and other network parameters (such as DNS server addresses) are dynamically allocated by a DHCPv6 server. This provides greater configuration flexibility and management capabilities, but requires additional DHCPv6 service support. It is understood that the target attribute can also be configured as SLAAC (Stateless Address AutoConfiguration) or dhcpv6-stateless (also known as stateless DHCPv6 mode). In SLAAC mode, clients independently configure IPv6 addresses by parsing prefix information from RAs and combining it with their own interface identifiers (such as EUI-64 or randomly generated). This method does not rely on additional server resources and is efficient and flexible. In DHCPv6-stateless mode, IPv6 address generation still follows SLAAC principles, but only obtains network configuration information other than the address (such as the DNS (Domain Name System) resolver) through the DHCPv6 service. This mode combines the efficiency of SLAAC with the flexibility of DHCPv6 and is suitable for scenarios where additional configuration is required but address allocation is automated. 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 needs of diverse network applications.

[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 primarily responsible for switch configuration, including VLAN numbers, IPv4 subnet segments and masks, and IPv6 subnet segments and masks. Therefore, configuring the target virtual local area network (VLAN), the first target subnet, and the second target subnet on the dual-stack switch may include: allocating a target port to the target virtual local area network, allocating a first target address and a first subnet mask to the first target subnet, and allocating a second target address and a second subnet mask to the second target subnet; and activating the target port corresponding to the target virtual local area network using a target command. For example, a VLAN named VLAN2000 is created, and FastEthernet0 / 1 port is assigned to VLAN 2000. VLAN 2000 is then configured with an IPv4 address of 192.168.1.1 / 24 with a 24-bit subnet mask, and an IPv6 address of 2402::1 / 64 with a 64-bit subnet mask. Finally, the VLAN interface is activated using the no shutdown command. It's understood that specific commands and configurations may vary depending on the switch and operating system (e.g., Cisco IOS, H3C, Foundry, etc.) from different vendors. The above examples apply to Cisco devices. Devices from other vendors may require different commands or configuration methods.

[0049] In this embodiment, Figure 4As shown, before creating the first cloud host and elastic network interface card (ENIC) under the target virtual local area network (VLAN), the dual-stack management and control center must verify the existence of the target VLAN on the target cloud computing platform using the target dual-stack application programming interface (API) based on the LAN ID of the target VLAN. In other words, whether the VLAN is available. If the target VLAN does not exist on the target cloud computing platform, the creation of the first cloud host and ENIC under the target VLAN is prohibited, and a prompt message indicating that the network information does not exist is returned. When creating a cloud host, you need to select a network and subnet. If the target VLAN exists on the target cloud computing platform, you can select the VLAN on the target cloud computing platform with the network number 2000. The corresponding VLAN network has two subnets: 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 "Enable IPv6" button 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 elastic network card interface will be called when the dual stack is enabled when creating the cloud host, the dual stack northbound interface will be called to create the elastic network card and encapsulate the parameters for creating the port. The IPv4 subnet can specify the IP address, while 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 cannot be turned off. If the cloud host only needs to meet the IPv4 protocol stack, you can uncheck the "Enable IPv6" button on the IPv4 subnet interface in the above steps. In this way, only the IPv4 subnet address will be assigned when creating the elastic network card, and the created cloud host will only have an IPv4 address. This implementation not only simplifies the operational process and ensures quick operation, but also allows users to freely configure the IPv4 and IPv6 segments of VLAN subnets based on 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. With IPv6 enabled on the VLAN network, information exchange with either IPv4 or IPv6 nodes is achieved, ensuring normal communication between 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, target information for the first cloud host and elastic network interface card (ENI), such as network, subnet, eni (Elastic Network Interfaces), and ecs (Elastic Compute Service, a simple, efficient, secure, reliable, and scalable computing service), is written to the target database. The IPv6 subnet IP address obtained in the preceding process is then configured for the first cloud host. For an Ubuntu 18 or later image, to configure the target subnet address for the first cloud host, first enter the cd / etc / netplan directory, then configure the IPv6 subnet IP address, mask, and gateway. Finally, execute the netplan apply command for the configuration to take effect. After the configuration is complete, to determine whether the first target connection between the first cloud host and the target subnet is functioning properly, log in to the first cloud host and determine whether the first cloud host can ping both the IPv4 gateway and the IPv6 gateway. If both can be pinged, the first target connection is functioning properly. The target database contains two tables containing ENI information: the ENI table (port) and the ENI association table (port_reference_ip). The ENI table stores the NI ID, name, IPv4 address, MAC address, network ID, and subnet ID. The ENI association table stores the NI ID, IPv6 address, and creation time.

[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 the preset dual-stack communication conditions are 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 a determination is made as to whether the second cloud host meets the preset dual-stack communication conditions. Specifically, 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, i.e., 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 then engage in dual-stack communication with the first cloud host. It is understood that there should be at least one second cloud host, and a corresponding number of second cloud hosts can be created based on user needs to enable 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, ensuring the availability of users' dual-stack services.

[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 local area network 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 local area network; the dual-stack northbound interface is mainly used to provide an interface for enabling dual stack to the upper 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 the 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.

[0061] 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 local area network 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 local area network; the dual-stack northbound interface is mainly used to provide an interface for enabling dual stack to the upper platform or third-party system or platform.
