Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0048] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuitry may be a single independent processing module, or may be incorporated in whole or in part into any of the other components of the computer terminal 10 (or mobile device). As described in the embodiments of the present application, the data processing circuitry serves as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0049] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the communication method between virtual machine instances across cloud servers in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, implementing the communication method between virtual machine instances across cloud servers of the above-mentioned application.

[0050] The transmission device is used to receive or send data via a network.

In one embodiment, the transmission device includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet.

[0051] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 (or mobile device).

[0052] Under the above operating environment, this application provides Figure 2 The communication method between virtual machine instances across cloud servers is shown. Figure 2 4 is a flow chart of a method for communicating between virtual machine instances across cloud servers according to a first embodiment of the present invention.

[0053] Step S201: When detecting that virtual machine instance 1 sends data information, the data is processed by virtual Ethernet network card 1 corresponding to virtual machine instance 1 to obtain processed data information, wherein virtual Ethernet network card 1 is pre-built in virtual machine instance 1.

[0054] The virtual Ethernet network card 1 mentioned above can be Figure 3As shown, virtual Ethernet network card 1 packages the data to be sent by virtual machine instance 1, and the processed data is then sent through eth0 of virtual machine instance 1. Using the pre-built virtual Ethernet network card in the cloud server's virtual machine instance, you can send communication data from the cloud server's virtual machine instance or receive communication data from virtual machine instances on other cloud servers.

[0055] It should be noted that in the embodiments of the present application, ECS is used as the basic resource to create virtual machine instances normally. These virtual machines have normal management-level network cards inside. The IP addresses of these network cards are automatically allocated and configured internally by ECS. These network cards are recorded as eth0.

[0056] In step S202, the processed data information is sent to the target virtual Ethernet network card of the target virtual machine instance, wherein the target virtual machine instance and the virtual machine instance 1 are set in different cloud servers.

[0057] The target virtual machine instance of the data recipient also pre-configures a target virtual Ethernet network card. Therefore, when the processed data is sent to the target virtual Ethernet network card of the target virtual machine instance, the target virtual Ethernet network card of the target virtual machine instance can receive the data sent by virtual Ethernet network card 1. Therefore, to achieve communication between virtual machine instances of different cloud servers, upon detecting that virtual machine instance 1 is sending data, before sending the processed data to the target virtual Ethernet network card of the target virtual machine instance, the method further includes: constructing a target virtual Ethernet network card in the target virtual machine instance.

[0058] Step S203: The processed data information is parsed by the target virtual Ethernet network card of the target virtual machine instance to realize data information interaction between virtual machine instances in different cloud servers.

[0059] After the target virtual Ethernet network card of the target virtual machine instance receives the processed data information, it parses it to obtain the parsed data information, which can be recognized by the target virtual machine instance, thereby realizing communication between virtual machine instances in different cloud servers.

[0060] Through the above steps, the method of using virtual Ethernet cards for cross-cloud server communication is adopted to achieve the technical effect of using virtual Ethernet cards to realize data information interaction between virtual machine instances in different cloud servers, thereby solving the technical problem that the container running inside the virtual machine or the IP address of the virtual machine network card cannot be registered with the software-defined network of the cloud server, causing the virtual machine container or virtual machine network card to be unable to communicate with each other across cloud server virtual machine instances.

[0061] Optionally, in the communication method between virtual machine instances across cloud servers of embodiment one of the present invention, building a virtual Ethernet network card in the virtual machine instance of each cloud server includes: building a vxlan tunnel interface within the virtual machine instance; creating a first virtual switch within the virtual machine instance; creating a pair of virtual network cards within the virtual machine instance, wherein the pair of virtual network cards includes: virtual network card one and virtual network card two, adding virtual network card one to the first virtual switch, and using virtual network card two as the data interface of the virtual machine instance; setting the status of the vxlan tunnel interface, the first virtual switch, virtual network card one and virtual network card two to the on state; and using the link composed of the vxlan tunnel interface, the first virtual switch, virtual network card one and virtual network card two as the virtual Ethernet network card.

[0062] Optionally, in the communication method between virtual machine instances across cloud servers of the first embodiment of the present invention, the method further includes: configuring a forwarding database in the virtual machine instance, wherein the forwarding database is used to guide the first virtual switch to forward the first packet data information;

[0063] In an embodiment of the present application, a vxlan tunnel interface is created inside each virtual machine instance, denoted as: vxlan-0. A bridge based on openvswitch is created (corresponding to the first virtual switch mentioned above), denoted as: mock-br. An fdb table entry (corresponding to the forwarding database mentioned above) is configured to guide the forwarding of the first packet of data link layer broadcasts and unknown unicasts. A pair of veth network cards is created, one of which is denoted as veth-br (corresponding to the virtual network card one mentioned above), and the opposite end of network card one (corresponding to the virtual network card two mentioned above) can be named as the network card that the business wants to actually use, for example: eth1 (indicating the virtual network card two mentioned above). Add veth-br to mock-br; set the link status of all newly created network cards and bridge device interfaces to the open state. After the above construction is completed, the link consisting of the vxlan tunnel interface, the first virtual switch, virtual network card one and virtual network card two is the virtual Ethernet network card in this application, such as Figure 3 The virtual Ethernet NIC 1 and the target virtual Ethernet NIC are shown as follows.

[0064] Through the above solution, a virtual Ethernet network card is built in each virtual machine instance. The data to be sent in the virtual machine instance can be packaged and processed through the vxlan tunnel interface in the virtual Ethernet network card. The processed data information can then be sent through eht0 of the virtual machine instance. Alternatively, when eht0 of the virtual machine instance receives data information sent by virtual machine instances of other cloud servers, the received data information can be parsed through the vxlan tunnel interface in the virtual Ethernet network card. The parsed data information can be recognized by the virtual machine instance, thereby realizing communication between virtual machine instances in different cloud servers.

[0065] When used by the upper-layer business system, the virtual Ethernet network card running in the virtual machine can be completely regarded as the Ethernet card of an ordinary physical server. It can be used to create any VLAN sub-interface, which can be used as the uplink interface of the container network.

[0066] It should be noted that eth1 is a virtual Ethernet network card that can be used similarly to a regular physical server. VLAN subinterfaces can be created on this card, and the card itself or its subinterfaces can be added to the service bridge to meet various service requirements. The vxlan tunnel interface can be provided by Linux or Open vSwitch.

[0067] In addition, before constructing a virtual Ethernet network card in each virtual machine instance of the cloud server, the method further includes: reading the node IP list configuration file through the agent component running on each node in the virtual machine instance; and sending the read virtual switch IP information and forwarding database information. That is, the software structure in the virtual machine includes an agent component running on each node, such as Figure 4 As shown, it is responsible for the basic network configuration initialization and regular detection status maintenance functions in the process of building the virtual Ethernet network card, thereby ensuring the normal operation of the virtual Ethernet network card.

[0068] Optionally, in the communication method between virtual machine instances across cloud servers of embodiment one of the present invention, when virtual network card 2 is used as the uplink interface of multiple container networks within the virtual machine instance, before processing data through the virtual Ethernet network card 1 corresponding to the virtual machine instance 1 to obtain processed data information, the method also includes: creating a second virtual switch within the virtual machine instance, wherein the second virtual switch is used to receive data information sent by multiple container networks; adding virtual network card 2 to the second virtual switch; processing data through the virtual Ethernet network card 1 corresponding to the virtual machine instance 1 to obtain processed data information includes: transmitting the data information sent from the second virtual switch to the first virtual switch through virtual network card 2; and in the first virtual switch, packaging the data information through the vxlan tunnel interface to obtain the processed data information.

[0069] like Figure 5 As shown, eth1 (virtual network card 2) is used as the uplink interface of a large number of container networks, and a linux bridge (second virtual switch) is created in the virtual machine instance. The Linux bridge is used to receive data information sent by multiple container networks; eth1 is added to the linux bridge; when a container in multiple containers sends data to virtual network card 2, the data information sent from the second virtual switch is transmitted to the first virtual switch through virtual network card 2; in the first virtual switch, the data information is packaged and processed through the vxlan tunnel interface to obtain the processed data information, thereby sending the data information sent by the container in the virtual machine instance, thereby realizing communication between virtual machine instances in different cloud servers.

[0070] Optionally, in the communication method between virtual machine instances across cloud servers of embodiment 1 of the present invention, virtual network card 2 extends multiple VLAN sub-interfaces, wherein the multiple VLAN sub-interfaces include virtual network card 21 and virtual network card 22, and before processing data through virtual Ethernet network card 1 corresponding to virtual machine instance 1 to obtain processed data information, the method further includes: creating multiple virtual switches within the virtual machine instance, wherein the multiple virtual switches include at least a third virtual switch and a fourth virtual switch, the third virtual switch is used to receive data information sent by at least one container 1 network, and the fourth virtual switch is used to receive data information sent by at least one container 2 network data information sent; adding virtual network card 21 to the third virtual switch, and adding virtual network card 22 to the fourth virtual switch, wherein the data information sent in the third virtual switch is transmitted to virtual network card 2 through virtual network card 21, and the data information sent in the fourth virtual switch is transmitted to virtual network card 2 through virtual network card 22; processing the data through the virtual Ethernet network card 1 corresponding to the virtual machine instance 1, and obtaining the processed data information includes: virtual network card 2 transmits the received data information to the first virtual switch, and in the first virtual switch, the data information is packaged and processed through the vxlan tunnel interface to obtain the processed data information.

[0071] In order to ensure the security and confidentiality of communication data, VLAN is used to isolate the network within the virtual machine instance. Specifically, eth1 (corresponding to the virtual network card 2 mentioned above) extends multiple VLAN sub-interfaces, such as Figure 6As shown, multiple Linux bridges (virtual switches) are created in the virtual machine instance, wherein the multiple virtual switches include at least Linux Bridge 1 (corresponding to the third virtual switch mentioned above) and Linux Bridge 2 (corresponding to the third virtual switch mentioned above), Linux Bridge 1 is used to receive data information sent by the container 1 network, and Linux Bridge 2 is used to receive data information sent by the container 2, container 3 and container 4 networks; eth1.9 (corresponding to the virtual network card 21) is added to Linux Bridge 1, and eth1.11 (corresponding to the virtual network card 22) is added to Linux Bridge 2, wherein the data information sent from Linux Bridge 1 is transmitted to eth1 (corresponding to the virtual network card 2) through eth1.9, and the data information sent from Linux Bridge 2 is transmitted to eth1 (corresponding to the virtual network card 2) through eth1.11; eth1 transmits the received data information to OpenVSwitch Mock-BR (corresponding to the first virtual switch mentioned above), and in the first virtual switch, the data information is packaged and processed through the VXLAN tunnel interface to obtain the processed data information.

Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of various embodiments of the present invention.

[0076] Example 2

[0077] Under the above operating environment, this application provides Figure 8 The communication method between virtual machine instances across cloud servers is shown. Figure 8 4 is a flow chart of a method for communication between virtual machine instances across cloud servers according to a second embodiment of the present invention.

[0078] Step S801: Displaying processed data information on a target interface, wherein, upon detecting that virtual machine instance 1 sends data information, processing the data using virtual Ethernet network card 1 corresponding to virtual machine instance 1 to obtain processed data information, wherein virtual Ethernet network card 1 is pre-configured in virtual machine instance 1;

[0079] Step S802: Displaying sending information on the target interface, wherein the sending information is used to instruct to send the processed data information to the target virtual Ethernet network card of the target virtual machine instance, wherein the target virtual machine instance and virtual machine instance 1 are set in different cloud servers;

[0080] Step S802: Display the parsing result of the processed data information on the target interface, wherein the parsing result is obtained by parsing the processed data information through the target virtual Ethernet network card of the target virtual machine instance to realize data information interaction between virtual machine instances in different cloud servers.

[0081] Through the above steps, the data interaction of virtual machine instances across cloud servers is displayed on the target interface by using a virtual Ethernet card for cross-cloud server communication, thereby achieving the technical effect of using a virtual Ethernet card to realize data information interaction between virtual machine instances in different cloud servers, thereby solving the technical problem that the container or virtual machine network card running inside the virtual machine cannot be registered with the software-defined network of the cloud server, causing the virtual machine container or virtual machine network card to be unable to communicate with each other across cloud server virtual machine instances.

[0082] Optionally, in the communication method between virtual machine instances across cloud servers of the second embodiment of the present invention, the method further includes: displaying the vxlan tunnel interface constructed in the virtual machine instance on the target interface; displaying the first virtual switch created in the virtual machine instance on the target interface; displaying a pair of virtual network cards created in the virtual machine instance on the target interface, wherein the pair of virtual network cards includes: virtual network card one and virtual network card two, adding virtual network card one to the first virtual switch, and using virtual network card two as the data interface of the virtual machine instance; setting the status of the vxlan tunnel interface, the first virtual switch, virtual network card one and virtual network card two to the on state on the target interface, and using the link composed of the vxlan tunnel interface, the first virtual switch, virtual network card one and virtual network card two as a virtual Ethernet network card.

[0083] In an embodiment of the present application, the process of constructing a virtual Ethernet network card is displayed on the target display interface. Specifically, a vxlan tunnel interface is created inside each virtual machine instance, which is recorded as: vxlan-0. A bridge based on openvswitch is created (corresponding to the first virtual switch mentioned above), which is recorded as: mock-br. An fdb table entry (corresponding to the forwarding database mentioned above) is configured to guide the forwarding of the first packet of data link layer broadcast and unknown unicast. A pair of veth network cards is created, one of which is recorded as veth-br (corresponding to the virtual network card one mentioned above), and the other end of network card one (corresponding to the virtual network card two mentioned above) can be named as the network card name that the business wants to actually use, for example: eth1 (representing the virtual network card two mentioned above). Veth-br is added to mock-br; the link status of all newly created network cards and bridge device interfaces is set to the open state. After the above construction is completed, the link consisting of the vxlan tunnel interface, the first virtual switch, virtual network card one and virtual network card two is the virtual Ethernet network card in this application.

[0084] Through the above solution, a virtual Ethernet network card is built in each virtual machine instance. The data to be sent in the virtual machine instance can be packaged and processed through the vxlan tunnel interface in the virtual Ethernet network card. The processed data information can then be sent through eht0 of the virtual machine instance. Alternatively, when eht0 of the virtual machine instance receives data information sent by virtual machine instances of other cloud servers, the received data information can be parsed through the vxlan tunnel interface in the virtual Ethernet network card. The parsed data information can be recognized by the virtual machine instance, thereby realizing communication between virtual machine instances in different cloud servers.

[0085] When used by the upper-layer business system, the virtual Ethernet network card running in the virtual machine can be completely regarded as the Ethernet card of an ordinary physical server. It can be used to create any VLAN sub-interface, which can be used as the uplink interface of the container network.

[0086] It should be noted that eth1 is a virtual Ethernet network card that can be used similarly to a regular physical server. VLAN subinterfaces can be created on this card, and the card itself or its subinterfaces can be added to the service bridge to meet various service requirements. The vxlan tunnel interface can be provided by Linux or Open vSwitch.

[0087] Furthermore, before building a virtual Ethernet network card in each cloud server's virtual machine instance, the method further includes: reading a node IP list configuration file through an agent component running on each node in the virtual machine instance; and distributing the read virtual switch IP information and forwarding database information. Specifically, the software architecture within the virtual machine includes an agent component running on each node, responsible for initializing the basic network configuration and maintaining periodic network status during the virtual Ethernet network card building process, thereby ensuring the normal operation of the virtual Ethernet network card.

[0088] Optionally, in the communication method between virtual machine instances across cloud servers of the second embodiment of the present invention, when virtual network card 2 is used as the uplink interface of multiple container networks within the virtual machine instance, the method also includes: before processing data through virtual Ethernet network card 1 corresponding to virtual machine instance 1 to obtain processed data information, a second virtual switch created within the virtual machine instance is displayed on the target interface, wherein the second virtual switch is used to receive data information sent by multiple container networks, and virtual network card 2 is added to the second virtual switch; the data information sent from the second virtual switch is transmitted to the first virtual switch through virtual network card 2; and the processed data information is displayed on the target interface by packaging the data information through the vxlan tunnel interface in the first virtual switch.

[0089] For example, use eth1 (virtual network card 2) as the uplink interface of a large number of container networks, create a linux bridge (second virtual switch) in the virtual machine instance, and the Linux bridge is used to receive data information sent by multiple container networks; add eth1 to the linux bridge; when the container in multiple containers sends data to virtual network card 2, the data information sent from the second virtual switch is transmitted to the first virtual switch through virtual network card 2; in the first virtual switch, the data information is packaged and processed through the vxlan tunnel interface to obtain the processed data information, thereby sending the data information sent by the container in the virtual machine instance, thereby realizing communication between virtual machine instances in different cloud servers.

[0090] Optionally, in the communication method between virtual machine instances across cloud servers of embodiment 2 of the present invention, virtual network card 2 extends multiple vlan sub-interfaces, wherein the multiple vlan sub-interfaces include virtual network card 21 and virtual network card 22, and the method further includes: before processing data through virtual Ethernet network card 1 corresponding to virtual machine instance 1 and obtaining processed data information, multiple virtual switches created in the virtual machine instance are displayed on the target interface, wherein the multiple virtual switches include at least a third virtual switch and a fourth virtual switch, the third virtual switch is used to receive data information sent by at least one container 1 network, and the fourth virtual switch is used to receive data information sent by at least one container 1 network. The virtual switch is used to receive data information sent by at least one container 2 network; the target interface displays that virtual network card 21 is added to the third virtual switch, and virtual network card 22 is added to the fourth virtual switch, wherein the data information sent from the third virtual switch is transmitted to virtual network card 2 through virtual network card 21, and the data information sent from the fourth virtual switch is transmitted to virtual network card 2 through virtual network card 22; virtual network card 2 transmits the received data information to the first virtual switch, and in the first virtual switch, the processed data information obtained by packaging the data information through the vxlan tunnel interface is displayed on the target interface.

[0091] In order to ensure the security and confidentiality of communication data, VLAN is used to isolate the network in the virtual machine instance. Specifically, eth1 (corresponding to the above-mentioned virtual network card 2) extends multiple VLAN sub-interfaces, and creates multiple Linux bridges (virtual switches) in the virtual machine instance, wherein the multiple virtual switches include at least Linux bridge1 (corresponding to the above-mentioned third virtual switch) and Linux bridge2 (corresponding to the above-mentioned third virtual switch). Linux bridge1 is used to receive data information sent by the container 1 network, and Linux bridge2 is used to receive data information sent by the container 2, container 3 and container 4 networks; eth1.9 (corresponding to the above-mentioned virtual network card 21) is added to Linux bridge1, and eth1.11 (corresponding to the above-mentioned virtual network card 22) is added to Linux bridge2, wherein the data information sent from Linux bridge1 is transmitted to eth1 (corresponding to the above-mentioned virtual network card 2) through eth1.9, and the data information sent from Linux bridge2 is transmitted to eth1 (corresponding to the above-mentioned virtual network card 2) through eth1.11; eth1 transmits the received data information to openvswitch mock-br (corresponding to the first virtual switch mentioned above) packages the data information in the first virtual switch through the vxlan tunnel interface to obtain the processed data information.

[0092] Through the above solution, multiple eth1-based VLAN sub-interfaces are used within the virtual machine instance to carry out VLAN-based network communication, ensuring the security and confidentiality of communication data.

[0093] It should be noted that the processing method in the method for communicating between virtual machine instances across cloud servers in Example 2 of the present application is the same as the processing method in the method for communicating between virtual machine instances across cloud servers in Example 1. Other processing methods will not be described in detail here.
